Washington DC - Sikorsky has attached main rotor blades to its CH-53K ground test vehicle (GTV) and will soon attach the tail rotor blades, according to officials from the company and the US Marine Corps.


The programme is on track to turn the rotors using the aircraft's GE38-1B turboshaft engines – the so-called "shakedown light-off" tests — by the end of the month, says Michael Torok, Sikorsky’s vice president of the programme.


Torok made his comments during a press briefing at the Navy League's Sea-Air-Space Exposition near Washington, DC, on 9 April.


He adds that development is progressing well on the heavy-lift helicopter, with first flight still scheduled for sometime near the end of this year.


The aircraft that will be making the first flight is nearly completed, though the company must still conduct tests of the main gear box, says Torok.


USMC Col Robert Pridgen, CH-53K programme manager, says Sikorsky and the military are seeking foreign customers, with potential customers including Germany and Israel, and he predicts interest will further materialise following first flight and as the company moves to production.


Officials say they have also received interest from international partners in the Asia Pacific region.


"Build it and they will come," Pridgen says.


The company has been testing the CH-53K’s seven main all-composite rotor blades and its four tail rotor blades at its headquarters in Stratford, Connecticut.


In December 2013, Sikorsky first powered up the GTV’s auxiliary power unit in Florida as part of the “bare-head light-off” tests of the engines and rotor without blades.


The GTV’s three main engines were started in January.


Despite similarities to the CH-53E Super Stallion, the CH-53K's three turbines can crank out 7,500shp each, compared with the 4,380shp GE T64 powerplants on the legacy platform.


The main and rail rotors have more surface area than the E-model, and a newly designed gearbox will allow the CH-53K to carry an external load of more than 12,200kg (26,900lb) over a mission radius of 110nm (204km).


That is triple the capacity of the E-model, according to Sikorsky.

VTOL X-Plane Program Takes Off



March 20th, 2014 By US Department of Defense  - defencetalk.com


For generations, new designs for vertical takeoff and landing aircraft have remained unable to increase top speed without sacrificing range, efficiency or the ability to do useful work. DARPA’s VTOL Experimental Plane (VTOL X-Plane) program seeks to overcome these challenges through innovative cross-pollination between the fixed-wing and rotary-wing worlds, to enable radical improvements in vertical and cruise flight capabilities.


In an important step toward that goal, DARPA has awarded prime contracts for Phase 1 of VTOL X-Plane to four companies: Aurora Flight Sciences Corporation; The Boeing Company; Karem Aircraft, Inc; Sikorsky Aircraft Corporation.


“We were looking for different approaches to solve this extremely challenging problem, and we got them,” said Ashish Bagai, DARPA program manager.


“The proposals we’ve chosen aim to create new technologies and incorporate existing ones that VTOL designs so far have not succeeded in developing. We’re eager to see if the performers can integrate their ideas into designs that could potentially achieve the performance goals we’ve set.”


VTOL X-Plane seeks to develop a technology demonstrator that could:

    Achieve a top sustained flight speed of 300 kt-400 kt

    Raise aircraft hover efficiency from 60 percent to at least 75 percent

    Present a more favorable cruise lift-to-drag ratio of at least 10, up from 5-6

    Carry a useful load of at least 40 percent of the vehicle’s projected gross weight of 10,000-12,000 pounds


All four winning companies proposed designs for unmanned vehicles, but the technologies that VTOL X-Plane intends to develop could apply equally well to manned aircraft. Another common element among the designs is that they all incorporate multipurpose technologies to varying degrees.


Multipurpose technologies decrease the number of systems in a vehicle and its overall mechanical complexity. Multipurpose technologies also use space and weight more efficiently to improve performance and enable new and improved capabilities.


The next major milestone for VTOL X-Plane is scheduled for late 2015, when the four performers are required to submit preliminary designs. At that point, DARPA plans to review the designs to decide which to build as a technology demonstrator, with the goal of performing flight tests in the 2017-18 timeframe.

Sikorsky And Turkey Sign Deal On Building Variant of Black Hawk Helicopter


March 5, 2014. David Pugliese Defence Watch


News release from Sikorsky:


Sikorsky Aircraft Corp., a subsidiary of United Technologies Corp. (NYSE: UTX), has signed agreements with the Turkish government and key Turkish aerospace contractors that license Turkey’s aerospace industry to manufacture 109 T-70 helicopters (Turkish variants of Sikorsky’s S-70i™ International BLACK HAWK helicopter) for operation by the Turkish Government, and to assemble 109 S-70i™ helicopters for Sikorsky.


The agreements license the transfer of certain manufacturing technology to Turkish industry, and provide for the potential to produce up to a total of 600 aircraft, including both T-70 units for Turkish indigenous use and S-70i™ aircraft for export over the next 30 years. The agreements are subject to requisite export approvals.


“This program is unprecedented in Sikorsky’s 90-year history,” said Sikorsky President Mick Maurer. “We have signed contracts that collectively will raise our already strong supplier and customer relationships in Turkey to levels that we expect will endure for decades. We are very pleased that these agreements also will potentially open additional markets for the world’s leading utility military helicopter while strengthening Turkish industry’s position as a world-class aerospace provider.”


Under the program, known as the Turkish Utility Helicopter Program, Sikorsky has signed agreements with the Turkish Undersecretariat for Defence Industries (SSM) and two Turkish defense contractors, Turkish Aerospace Industries, Inc. (TAI) and Aselsan A.S. TAI is the prime contractor for T-70 licensed production and assembly in Turkey for multi-mission use by the Turkish government. The aircraft will be assembled in Turkey by TAI and will include components supplied by Sikorsky and other American and Turkish companies. Aselsan will develop a new cockpit avionics system that will be featured in the T-70 aircraft.


Turkey’s Defence Industry Executive Committee has reported a total program value of $3.5 billion, inclusive of the work to be performed by Sikorsky, TAI and other TUHP suppliers. In addition to the work with TAI and Aselsan, Sikorsky will expand the manufacturing capability of Alp Aviation, which is 50 percent owned by Sikorsky.

Sikorsky Says It Will Deliver Eight More Cyclone Helicopters To Canada By The End of December


November 2, 2013. David Pugliese Defence Watch


Sikorsky’s chief financial officer says the company plans to deliver eight more Cyclone helicopters to Canada by the end of December.


Greg Hayes discussed the move during a third-quarter earnings phone call a couple of days ago with analysts. His statement is similar to what Sikorsky has been stating over the last little while.


The 8 Cyclones are in addition to the four already at Shearwater and being used for training….but not formally accepted by the Canadian government.


“Good news is the aircraft are up in Shearwater,” Hayes said. “They are flying. We’re getting traction with the customer. I think everybody recognizes they want to find a solution here, both at the Sikorsky and at the Canadian government level.”

Public Works has stated, however, that “training does not constitute acceptance of an interim helicopter.”


Dominic Perry of Flight Global has also noted that Hayes has hinted that contract negotiations with Canada could be imminent. “I’m going to be very cautious here. That’s atypical with me. I would say that we’re making progress, although it’s slow. And I think again, we haven’t really started formal contract negotiations,” said Hayes.

Sikorsky Completes Initial Tests of 1st Rotor Blades for CH-53K Helicopter


Nov 1, 2013 ASDNews Source : Sikorsky Aircraft, A United Technologies Company


Sikorsky Aircraft has successfully completed the initial phase of testing for the first-ever main and tail rotor blades manufactured for the U.S. Marine Corps' CH-53K heavy lift helicopter program. Designed specially to help meet the Marine Corps requirement to lift the aircraft's maximum gross weight of 88,000 pounds, the all-composite blades are the largest and most technologically advanced ever produced by Sikorsky, a subsidiary of United Technologies Corp. (NYSE: UTX).


"These new blades are an important feature of the CH-53K helicopter's ability to lift almost three times the payload compared to the CH-53E Super Stallion™ aircraft it will replace later this decade," said Mike Torok Sikorsky's CH-53K Program Vice President. "Advanced geometric shaping, high strength composite materials and a flaw tolerant design all come into play to provide unmatched performance, reliability, and survivability."

Le Brésil va recevoir deux S-70B


31.10.2013 Helen Chachaty - journal-aviation.com



L’US Navy a notifié à Sikorsky un contrat de 86,7 millions de dollars pour la fourniture de deux hélicoptères S-70B destinés au Brésil, par le biais du programme FMS (Foreign Military Sales). Les deux appareils devraient être livrés au plus tard en juin 2017 et viendront compléter la flotte de la marine brésilienne, qui avait réceptionné ses deux premiers hélicoptères en août 2012, selon deux commandes passées en 2009 et 2011. Les S-70B Seahawk sont destinés aux missions de surveillance et de lutte anti-sous-marine et de lutte en surface.

Le remplacement des hélicoptères maritime ou l’ABC d’un échec

Un hélicoptère CH-124 Sea King Canadien effectue des exercices d'appontage sur le USS Pearl Harbor (LSD 52) pendant PANAMAX 2007 (Photo: Archives/US Navy)


29/10/2013 par Jacques N. Godbout – 45eNord.ca


L’affaire du retard de Sikorsky dans la livraison de l’hélicoptère maritime, c’est l’ABC d’un échec. Après l’échec du plan «A», et en l’absence d’un plan «B» crédible, on semble en être arrivé à un plan «C» qui ne serait rien d’autre que le plan «A» modifié une énième fois.


Après tout le bruit autour de l’idée d’un plan «B» qu’il y a eu cet automne et de la possible rupture du contrat avec Sikorsky, les fonctionnaires du ministère de la Défense nationale s’attendent maintenant à ce que le gouvernement donne une fois de plus une nouvelle chance à l’entreprise aérospatiale américaine d’enfin livrer ses hélicoptères Cyclones pour remplacer les vieux Sea Kings.


Sikorsky avait signé en 2004 un contrat pour livrer 28 hélicoptères pour remplacer nos vénérables Sea Kings, qui ont fêté leur 50e anniversaire cette année, mais le fournisseur a maintenant cinq ans de retard et a seulement construit quatre appareils d’«essai», refusés d’ailleurs par le gouvernement.


Au printemps dernier, la ministre des Travaux publics de l’époque Rona Ambrose avait réclamé une analyse indépendante pour savoir si Sikorsky pouvait respecter son engagement et, au début du mois d’octobre, de hauts responsables de la Défense nationale et des Travaux publics s’étaient réunis à huis clos avec des rivaux de Sikorsky pour préparer un plan «B».


Mais, attention, une annulation du contrat pourrait coûter très cher, prévenait l’expert en matière de défense de l’Université Dalhousie, Jean-Christophe Boucher lors d’une entrevue à 45eNord.ca.


Devant le coût élevé d’une annulation, le gouvernement pourrait aussi acheter des appareils déjà éprouvés, comme ceux d’Augusta Westland, pour faire le pont entre nos vieux Sea Kings et les nouveaux Cyclones qui tardent à arriver.


Les responsables au ministère de la Défense voudraient maintenant, semble-t-il, que leurs collègues de Travaux publics et Services gouvernementaux Canada avalisent les changements nécessaires pour pouvoir enfin la livraison accepter des hélicoptères Cyclone provisoires de Sikorsky.


Sikorsky propose en effet de fournir au Canada ce que l’entreprise appelle des hélicoptères provisoires pas entièrement équipés avec tout le matériel nécessaire, tout en affirmant qu’il serait alors en mesure des aéronefs entièrement conformes à partir de 2015.


Publiquement, le gouvernement conservateur a adopté une ligne dure – déclarant qu’il n’acceptera pas les hélicoptères provisoires parce qu’ils ne répondent pas aux spécifications, et ne s’est pas fait prier pour dévoiler qu’il examinait sérieusement un plan «B». Comme on l’a vu précédemment.


Toutefois, de hauts responsables gouvernementaux , y compris les sous-ministres à la Défense et aux Travaux publics, ont eu plusieurs rencontres depuis décembre 2011 avec des représentants de Sikorsky pour paver la voie à la livraison des hélicoptères provisoires.


Travaux publics avait d’ailleurs déjà modifié le contrat de Cyclone deux fois dans le passé afin de donner à Sikorsky plus de temps pour livrer l’hélicoptère.


Aujourd’hui, malgré les dénégations du gouvernement Harper, des sources au sein de l’industrie disent qu’il y a effectivement des discussions sur d’autres modifications au contrat.


Par ailleurs, Sikorsky a livré quatre Cyclones à la base de Shearwater en Nouvelle-Écosse , mais ils restent toujours la propriété de l’entreprise.


On ne sait pas si cela peut être indicatif de ce que fera finalement le gouvernement dans cette histoire, mais le gouvernement conservateur a annoncé cet été qu’il allait permettre aux pilotes et aux techniciens de se former sur les hélicoptères Cyclone, bien qu’il en ait refusé officiellement la livraison parce qu’ils ne répondent du contrat.


Alors, si on résume, A=B=C=A, ou quelque chose comme ça…

21 octobre 2013 par Thierry Dubois – Aerobuzz.fr


Dernier développement en date dans les hélicoptères sans pilote, le programme Matrix de Sikorsky, qui vise à rendre l’appareil plus autonome jusqu’à l’automatisation complète. AgustaWestland travaille sur un petit SW-4 militaire « dronisé » pour le Royaume-Uni.

L’hélicoptériste Sikorsky s’apprête à procéder aux premiers décollage et atterrissage entièrement autonomes de son démonstrateur Sara, un S-76 modifié en vue d’une automatisation graduelle. Le programme de recherche et développement Matrix vise à assister ou remplacer le pilote, suivant la mission.

Sikorsky a jusqu’ici fait voler le Sara sur des trajectoires qui débutent et se terminent par un stationnaire. Les commandes de vol électriques étaient le principal changement sur le S-76. Avec les atterrissage et décollage, les ingénieurs et pilote d’essai passent la vitesse supérieure. Ils vont ensuite intégrer un logiciel capable de prendre des décisions. Ils ajouteront simultanément des capteurs – lidar, caméras, radar et autres.

En exploitation civile, le concept offre plusieurs degrés d’autonomie. Il pourrait fournir au pilote une aide à la décision – afin de choisir de poursuivre la mission ou non. Il pourrait être utile lors d’une autorotation, qui deviendrait automatique, avance-t-on chez Sikorsky. Il pourrait aussi assurer un retour automatique à la base en cas de difficulté météo. Un hélicoptère sans pilote pourrait livrer du fret sur une plate-forme pétrolière. Le programme Matrix de Sikorsky a commencé il y a deux ans et se poursuivra pendant encore trois ans.

De son côté, AgustaWestland a présenté au salon DSEI un concept de drone « pour être prêt en 2020 », explique un porte-parole. Plus précisément, il s’agit de développer les technologies qui permettent à un même hélicoptère d’être piloté ou non. Le constructeur compte tirer parti des compétences d’autres sociétés du groupe Finmeccanica, comme l’électronicien Selex.

AgustaWestland travaille à plus court terme, dans le cadre d’un contrat avec le ministère britannique de la défense, sur la « dronisation » d’un SW-4 pour la Royal Navy. Eurocopter avait fait voler un EC145 sans pilote en avril dernier.

Sikorsky S-97 Raider Begins Final Assembly

Sep. 23, 2013 - By AARON MEHTA – Defense News


WASHINGTON — Sikorsky will begin final assembly of its S-97 Raider helicopter prototype this week, according to company officials.


That puts the helicopter manufacturer — which is competing for the US Army’s Armed Aerial Scout program — on track for a first flight at the end of 2014.


“It’s just a really exciting foundational milestone for us, and it’s great to be leaving the design phase of Raider and getting into the build phase,” Chris Van Buiten, Sikorsky Innovations vice president, said.


The Raider is based on the X-2 technology developed by Sikorsky in the late 2000s, but grows the size and weight significantly. Where the X-2 demonstrator was a one-person, 5,000-pound platform, the Raider will be roughly 11,000 pounds with room for six troops in its combat assault mode. In reconnaissance mode, that space could be used for extra equipment or ammunition.


Despite that growth, Sikorsky executives are confident the design will bring a mix of speed and maneuverability that helicopters have not yet achieved.


“This thing has to fly faster than 220 knots” at cruising speed, Van Buiten said when asked about key performance targets. “It has got to do more than a 3G turn at speed. It has to demonstrate hover at 10,000 feet and 95 degrees. Those are the non-negotiables.”


The fuselage, assembled by Aurora Flight Sciences in a West Virginia facility, arrived at Sikorsky’s West Palm Beach, Fla., facility Sept. 20. A composite airframe, the fuselage has been tested to tolerate bird strikes at 230 knots and has shown very low drag, according to the company.


The Armed Aerial Scout program aims to replace the Army’s fleet of OH-58 Kiowa Warriors, in use since the late 1960s. The winner of the program is expected to last well past 2050, meaning the competition would be a long-term windfall for the winner.


Army officials visited with competitors AgustaWestland, Boeing, EADS and Bell Helicopter during the summer of 2012, but the top acquisition adviser to the secretary of the Army told a congressional hearing in May that “we didn’t find a single aircraft that was out there that could meet the Army’s requirements.”


Sikorsky is confident is can fill that role — assuming the replacement program can get funding.


As with all programs in the Pentagon, the Armed Aerial Scout is facing budget challenges. Speaking Sept. 19 on the Hill, Army Chief of Staff Gen. Ray Odierno indicated the program is at risk if sequestration continues.


“In the event sequestration-level discretionary caps continue into FY14, we will assume significant risk in our combat vehicle development,” Odierno said. “In our aviation program, we cannot afford to procure a new Armed Aerial Scout program and we will be forced to reduce the production and modernization of 25 helicopters.”


Despite such warnings, Sikorsky remains confident the Army will find the money to fund the program, according to Steve Engebretson, the company’s Advanced Military Programs director.


“It’s a tough financial environment, but the fact Odierno highlighted this program reflects the level of importance the Army has in that mission,” he said. “To me, it’s at least a sign that if there is a way the Army can get that program going, they will find a way to do that.”


“We understand the climate we’re operating in,” added Van Buiten. “We’re committed to demonstrating this technology, but we understand the customer has a lot of priorities to balance. Our job is to open up the aperture of what’s possible with them.”


Both men can be sanguine, in part, because the development of the Raider has been entirely funded by Sikorsky and its industry partners. While the S-97 is being designed with Armed Aerial Scout in mind, it will also serve as a test bed for further X-2 technologies, which could then go onto future Sikorsky products. Additionally, the company sees the Raider as a demonstrator for a larger machine that would fit the Army’s Joint Multi-Role helicopter replacement program for the service’s Blackhawk fleet.


In other words, the company sees ways to recoup its investment in the prototype even if the program never comes through. That company investment is a point of pride for Van Buiten, whose team was responsible for the design and creation of the Raider.


“We’ve created this innovations group, and one of our charters is to demonstrate differentiating technology that creates competitive advantages for us or all new capability for our customers,” he said. “We don’t have the luxury of using traditional timelines and budgets to do it.”


If the project continues on target, the Raider prototype’s first flight will take place roughly 48 months after its clean-sheet design, a much faster pace than the defense industry normally sees. While costs are not set, the company has estimated it could produce the platform in production quantities for as little as $15 million a copy, including mission system packages.


There is also a potential international market for the technology through the Foreign Military Sales program. The company has been in contact with “several very close allies of the US” about the technology, Engebretson said.


While declining to name which countries might be interested, he said the “international interest roughly equals the quantities the US government is thinking about, in the hundreds.”

Hélicoptère Sikorsky CH-148 Cyclone



5 septembre 2013 radio-canada.ca – (La Presse Canadienne)



Le gouvernement Harper pourrait être prêt à jeter l'éponge dans le projet d'achat des hélicoptères CH-148 Cyclone, retardé depuis des lunes, et a même dépêché en Grande-Bretagne des représentants du secteur militaire pour évaluer d'autres appareils.


Selon des sources du ministère de la Défense, l'équipe, qui inclut un officier de la division des besoins en ressources aériennes des Forces aériennes, a visité une base située dans le sud du Royaume-Uni, récemment, pour jeter un coup d'oeil aux hélicoptères HM-1 Merlin de la Royal Navy.


Une porte-parole de la ministre des Travaux publics, Diane Finley, a confirmé que le gouvernement étudiait des options « autres » que les hélicoptères Cyclone, qui accusent un retard de plusieurs années et dont les coûts ont largement dépassé les estimations budgétaires.

July 25, 2013. David Pugliese - Defence Watch


News release from Sikorsky:


Sikorsky Aircraft Corp., a subsidiary of United Technologies Corp. (NYSE:UTX), has delivered the 400th MH-60 SEAHAWK helicopter to the U.S. Navy. The milestone consists of 166 MH-60R anti-submarine and anti-surface warfare helicopters, and 234 MH-60S utility/armed helicopters. The Navy took possession of the 400th, an MH-60R aircraft, on June 24.


“MH-60 multi-mission aircraft are among the most reliable and sophisticated maritime helicopters in the world,” said Capt. James Glass, Navy Program Manager, H-60 Programs. “The Navy intends to continue flying these helicopters well into the 2030s.”


MH-60S (“Sierra”) helicopters carry supplies and sailors between ships, and protect U.S. ships from surface threats in an armed configuration. Sierra aircraft are expected to take on an airborne mine countermeasures role starting in 2014.




MH-60R (“Romeo”) helicopters employ radar, acoustic sonar, communications links, torpedoes and air-to-surface missiles for the anti-surface and anti-submarine warfare roles.


Sierra aircraft, which entered U.S. Navy service in 2002, will remain in full rate production through 2015 as part of a currently planned production run of 275 aircraft. Romeo helicopters, operational since 2006, are currently scheduled to remain in production through 2017 to meet the Navy’s 291 intended aircraft buy. The two aircraft models have accumulated a combined 660,000 flight hours to date.


“Mission success in the harsh maritime environment is a testament to the men and women of the U.S. Navy who fly and maintain these SEAHAWK aircraft,” said Dave Zack, Sikorsky Maritime Programs Director. “The skilled workforce at Sikorsky, and our supplier teammates, remains committed to building and supporting the world’s most reliable, durable and operationally effective maritime helicopter.”


All but two of the 400 MH-60 SEAHAWK aircraft delivered to date are operated by the U.S. Navy. In 2011, the Royal Thai Navy took delivery of two MH-60S helicopters via the U.S. Government’s Foreign Military Sales (FMS) program.


The U.S. Navy has acquired all MH-60 SEAHAWK aircraft since 2002 via five-year contracts. The current 2012-2017 contract funds 193 MH-60R/S SEAHAWK helicopters, plus another 24 Romeo helicopters for the Royal Australian Navy. Actual production quantities will be determined year-by-year over the life of the program based on funding allocations set by Congress and Pentagon acquisition priorities.


Sikorsky will deliver the first four RAN aircraft (before mission systems integration) during 2013. Additionally, Sikorsky will deliver the first two (of nine) Romeo aircraft for the Royal Danish Navy during 2014.


Sikorsky produces the MH-60R/S SEAHAWK aircraft models on separate production lines at its final assembly facility in Stratford, Conn. Avionics prime contractor Lockheed Martin performs all mission systems integration for Romeo aircraft at its Mission Systems and Training facility in Owego, N.Y., and also produces the digital cockpit common to both Romeo and Sierra models.

09/07/2013 par Nicolas Laffont – 45eNord.ca


Dans le cadre d’un plan à long terme du Département américain de la Défense, l’US Army a produit une vidéo pour attirer des soumissionnaires et les inciter à repousser les limites de la technologie dans le développement d’un hélicoptère de nouvelle génération et de ses flottes utilisant les rotors basculants.


«J’ai besoin de visionnaires de l’aviation», lance ainsi Bill Lewis, directeur de la Direction du développement de l’aviation de l’armée de terre, dans la vidéo de 7 minutes. «Le seul facteur limitant est votre imagination.»


En réponse à la vidéo, la société Hurst, basée au Texas (et faisant partie de Bell), a produit sa propre vidéo mettant en vedette des acteurs qui défoncent rapidement des portes et «accomplissent leur mission» avec l’aide du V-280 Valor, la version du rotor basculant de Bell pour un avion conjoint multi-rôle.


La production de Bell, mettant en valeur le Valor, commence avec deux enfants jetant leurs cartables pour voir la vidéo. «Chouette appareil du futur» , dit un gamin. «J’ai bien hâte de voler avec ce bad boy.»

Dans les deux vidéos, le thème semble être le pouvoir de transformation de la technologie pour façonner les futures guerres en des jeux de clic de souris dans lesquels les gentils ne meurent jamais, et avec encore moins de sang.


Bell Helicopter, AVX Aircraft Co. et une coentreprise de Boeing Co. et Sikorsky Aircraft Corp. ont d’ores et déjà soumis leur concept à l’armée américaine d’un Démonstrateur de technologie conjoint multi-rôle.


L’armée envisage de prendre une décision initiale sur le démonstrateur en septembre, avec un prototype volant prêt pour 2017.


Les propositions de Bell, AVX et Boeing-Sikorsky pour le Démonstrateur de technologie conjoint multi-rôle ne sont qu’un premier pas dans le plan global du Pentagone annoncé en 2011 d’avoir l’armée prendre l’initiative des prototypes pour remplacer la flotte vieillissante de plus de 4000 hélicoptères dans toutes les armes.


«L’avion de nouvelle génération devra être un ensemble beaucoup moins coûteux à exploiter que la flotte actuelle» et être prêt à entrer sur la ligne de front dans les années 2020, a déclaré le major-général William Crosby, responsable du programme de l’aviation pour l’armée.


«Même avec tout l’excellent travail que nous faisons pour la mise à niveau et le soutien de la flotte actuelle, il est maintenant temps d’investir dans la science et la technologie nécessaires pour développer la future flotte», a dit William Crosby.


«Nous avons encore des plates-formes élévatrices verticales de troisième génération conçues pendant la période de la guerre du Vietnam, il y a près de 50 ans», a-t-il dit. «Notre flotte actuelle ne durera pas éternellement et il y a des limites à notre capacité d’améliorer les modèles actuels pour répondre aux besoins futurs.»

Le premier hélicoptère MH-60R Seahawk Romeo de la Royal Australian Navy a effectué son premier vol d’essai à l’usine de Sikorsky, dans le Connecticut, le 26 juin dernier. L’appareil, immatriculé N48-001, est resté une heure et vingt minutes dans les airs, pour effectuer toute une série de tests tels que la performance des moteurs, l’analyse des vibrations et la navigation.


L’hélicoptère multimissions va à présent être transféré à l’usine de Lockheed Martin d’Owego, afin de procéder à l’intégration de ses systèmes de mission et de ses capteurs. Les deux premiers MH-60R devraient être livrés à la marine australienne en décembre 2013 et seront notamment déployés pour des missions de lutte anti-sous-marine et de lutte anti-surface.


L’Australie s’était décidée pour les MH-60R de Sikorsky en juin 2011, au détriment du NH90 NFH. Le contrat initial portait sur 24 exemplaires, destinés à remplacer les S-70B Seahawk. La vente à l’Australie est la première exportation de l’hélicoptère multimissions. La nouvelle flotte devrait être équipée de torpilles MK54 (Raytheon), de missiles AGM-14 Hellfire (Lockheed Martin) et de mitrailleuses.

  STRATFORD, Connecticut - Sikorsky Aircraft Corp. has received a $435 million U.S. Navy contract to build four production-representative CH-53K heavy lift helicopters for the U.S. Marine Corps. Designated as System Demonstration Test Articles (SDTA), the four aircraft will enable the Marines to conduct operational evaluation of the new helicopter system in support of Initial Operational Capability in 2019.



“The four SDTA aircraft are based on the configuration of the fourth and final flight test aircraft currently being assembled on the prototype production line,” said Dr. Michael Torok, Sikorsky’s CH-53K Program Vice President. “We truly appreciate the high level of confidence the Navy and Marine Corps have shown to the CH-53K team as we move forward with this important next phase of the program.”


The Navy has included the SDTA helicopters as an additional line item under the existing $3.5 billion System Development and Demonstration (SDD) contract initially awarded to Sikorsky in April 2006. The contract schedule requires that Sikorsky deliver the first SDTA aircraft in 39 months, and the fourth by the end of March 2017, when the Marines will begin operational evaluation. The contract’s cost-plus-incentive fee arrangement incentivizes Sikorsky to deliver early. Sikorsky will perform final assembly of the SDTA aircraft at the company’s Florida Assembly and Flight Operations facility in West Palm Beach.


To date, Sikorsky has delivered two of the seven SDD CH-53K aircraft – the Ground Test Vehicle and the Static Test Article – into the test program, and is finalizing assembly of the four flight test aircraft and the Fatigue Test Article. First flight of a CH-53K prototype aircraft is expected in late 2014.


Once the SDTA aircraft enter operational evaluation in 2017, the Marine Corps will verify the CH-53K helicopter’s capability to carry 27,000 pounds over 110 nautical miles under “high hot” ambient conditions, nearly tripling the external load carrying capacity of the current CH-53E Super Stallion™ helicopter.


Technology enablers for increased lift include three 7,500-shaft-horsepower GE38-1B engines; a split torque transmission design that more efficiently distributes engine power to the main rotors; fourth-generation composite rotor blades for enhanced lift; and a composite airframe structure for reduced weight.


"The SDTA contract represents an exciting and significant milestone in our program," said Col. Robert Pridgen, the Heavy Lift Helicopters program manager for the Naval Air Systems Command. "We are well on our way to making the CH-53K a reality for our Marines and our Naval fleet. The capability this aircraft brings, in every clime and place, is critical to sustaining the future missions of the Marine Air/Ground Task Force. The future of heavy lift is bright."


Per the current program of record, the Navy intends to order an additional 196 CH-53K aircraft as part of a separate production contract to stand up eight operational squadrons and one training squadron to support the Marine Corps’ operational requirements. Eventual production quantities would be determined year-by-year over the life of the program based on funding allocations set by Congress and the U.S. Department of Defense acquisition priorities.


Sikorsky Aircraft Corp., based in Stratford, Conn., is a world leader in helicopter design, manufacture, and service. United Technologies Corp., based in Hartford, Conn., provides a broad range of high technology products and support services to the aerospace and building systems industries.

Bell Helicopter V-280 Valor tiltrotor design

Bell Helicopter V-280 Valor tiltrotor design

Jun. 6, 2013 by Dave Majumdar – FG


Washington DC - Bell Helicopter says that its V-280 Valor third-generation tiltrotor design has been selected by the US Army for its Joint Multi-Role technology demonstrator (JMR-TD) programme.


"The V-280 Valor will provide the army's most sought-after capability, with a cruise speed of 280kt [519km/h]," says Keith Flail, director of Bell's future vertical lift effort. The service hopes to develop an aircraft that can achieve a cruise speed of at least 230kt for the JMR-TD effort and its follow-on Future Vertical Lift programme.


Flail says the V-280 improves on the technology found in the Bell Boeing V-22 Osprey and is being designed to provide "outstanding" low-speed agility, multiple-g high-speed manoeuverability, superior fuel efficiency and improved range capabilities. Much of the aircraft's handling characteristics will be due to a new triple redundant fly-by-wire system that Bell hopes to incorporate into the machine.


The aircraft is also being designed to hover out of ground effect at a pressure altitude of 1,830m (6,000ft) at an ambient temperature of 35˚C (95˚F). Bell claims the V-280 will cruise at speeds of 280kt true airspeed and have a combat range of between 500nm (926km) and 800nm. It should also be able to self-deploy over a distance of 2,100nm.


Flail also claims the aircraft will have improved reliability and reduced costs, because the new clean sheet design reduces complexity compared to previous generation tiltrotors.


Bell's main competitor during the JMR-TD programme is expected to be a team consisting of Sikorsky and Boeing, which was its partner on the V-22. The two companies are pitching a high-speed compound helicopter design based on Sikorsky's self-funded X2 prototype for the army technolody demonstrator effort.

US Army selects Bell, Sikorsky/Boeing team for JMR demonstration

“The Sikorsky Boeing team is extremely pleased to have been invited by the US Army to negotiate a technology investment agreement for the Joint Multi-Role Technology Demonstrator Phase I programme,” the two companies say. “Our team brings a shared commitment to invest in next-generation rotorcraft technology based on Sikorsky’s X2 rigid rotor coaxial design.” Meanwhile, EADS North America recently told the army that it will drop out of the programme.


The army is expected to award JMR-TD contracts by September 2013, with first flights scheduled for 2017. The programme is expected to inform the Future Vertical Lift programme, which aspires to field a new medium-lift high-speed rotorcraft design to replace the Sikorsky UH-60 Black Hawk series in the 2030s. It could also spawn an effort to replace the Boeing AH-64E Apache attack helicopter. That market could be worth as much as $100 billion, according to Bell.

Turkey Says $3.5B Helo Deal with Sikorsky Is Near

May. 7, 2013 By BURAK EGE BEKDIL – Defense news


ANKARA — Turkish procurement officials said they are near to signing a $3.5 billion contract with Sikorsky Aircraft for the co-production of scores of utility helicopters.


Turkey’s procurement agency, the Undersecretariat for Defense Industries (SSM), posted on its web page May 6 that it had come to the final round of contract negotiations on the deal.


Turkey in 2011 selected Sikorsky Aircraft as its partner company to lead production of the country’s next-generation utility helicopters. Sikorsky, with its T-70, the Turkish version of its S-70 Black Hawk International, defeated Italian-British AgustaWestland.


A contract has been pending since then and industry sources rumored major problems during contract negotiations. The first batch of the co-production program involved 109 platforms.


“We have come a long way to put the final seal on the deal. We faced tough moments during talks but we have now reached a point that satisfies both parties,” a Turkish official familiar with the program said May 7.


The S-70 Black Hawk International is used by the militaries of dozens of countries, including Turkey. AgustaWestland had competed with its TUHP 149, the Turkish version of its newly developed A-149.


The first batch will be for 109 utility helicopters, but with follow-on orders more than 600 platforms could be built at a cost of more than $20 billion, according to defense analysts.


Sikorsky and AgustaWestland had announced benefit packages worth billions of dollars each. Several Turkish companies, most notably Turkish Aerospace Industries, will take part in the joint production.


Most of the helicopters in the first batch will go to the military, with the Gendarmerie receiving the largest portion, and the Army, Navy, Air Force and the Special Forces Command all getting their shares. The remaining choppers will go to the Security Directorate, meaning the police forces, and to the Firefighting Department.
