La Chine modernise son centre d’entrainement aéronaval

 

 

23 décembre 2013  par Daniel Favre - Info-Aviation

 

Une photo satellite prise par Astrium le 25 octobre 2013 révèle l’étendue de la modernisation de la base Huangdican destinée à la formation des pilotes chinois sur porte-avions.

 

L’Ukraine n’a pas visiblement pas réussi à convaincre la Chine de louer sa base d’entraînement sur porte-avions Nazemniy Ispitatelno-Tryenirovochniy Kompleks Aviatsii (NITKA). La Chine a préféré créer sa propre structure de formation ce qui montre sa volonté de développer sa puissance aéronavale comme un moyen de projection au large des côtes.

 

Situé sur la côte nord-ouest du golfe de Bohai, la base Huangdicun est environ à 8 km au sud de Xingcheng dans la région militaire de Shenyang. La construction du centre de formation a débuté en 2008 et s’est terminée en 2012. Le premier vol d’essai a été réalisé avec un chasseur Shenyang J-15 Flying Skark en janvier 2012.

La base Huangdicun possède de nombreuses fonctionnalités nécessaires à la formation des futurs pilotes à bord du porte-avions Liaoning, et d’autres bâtiments à venir. Des ponts d’atterrissage équipés d’un ensemble complet de câbles et le marquage du pont qui reprend la superstructure du Liaoning. Une deuxième zone adjacente à la piste principale contient deux autres rampes en saut à ski.

 

L’imagerie satellite révèle la présence de 24 hangars probablement pour loger des J-15. Mais il s’agit plutôt d’abris mobiles que des structures permanentes. On aperçoit aussi trois hangars permanents de 36 x 55 m qui pourraient être destinés aux hélicoptères. La taille des hangars permet également d’héberger des avions d’alerte précoce.

 

La base Huangdicun AB permet à la Chine d’assurer la formation de ses pilotes sur son propre sol au sein même de son complexe aéronaval. Le NITKA de l’Ukraine offrait néanmoins une solution idéale pour les Chinois puisque l’entraînement s’effectue sur le Su-33 dont le J-15 est une copie conforme.

 

La base Huangdicun fournit aussi des précisions sur la conception du futur porte-avions chinois. Par exemple, la présence de deux tremplins distincts avec brin d’arrêt indiquent que le prochain porte-avions conservera le décollage court (STOBAR) déjà utilisé sur le Liaoning.

New J-10 Shows Comprehensive Rather Than Partial Improvements

(Source: People's Daily Online; published Nov. 12, 2013)

 

On November 6th Zhang Jigao, deputy chief designer of the J-10 fighter, spoke about the improved model J-10 publicly for the first time in the AVIC flight test center. Zhang Jigao told People's Daily Online reporters that the overall performance of the J-10 will be comprehensively improved in areas such as aerodynamic layout, mission system, and the approach to maintenance.

 

In March 2009, pictures of our improved model J-10 fighters appeared for the first time on the Internet, and netizens quickly began to call it the "J-10B".

 

Over the last five 5 years, several images of the test J-10B have appeared online, attracting widespread attention from netizens, military enthusiasts, and even foreign media.

 

U.S. military expert Richard Fisher recently pointed out that the J-10B is a so-called "fourth and a half" generation fighter equipped with modern airborne technology and an advanced radar system, which is about to be delivered to the PLA Air Force.

 

Zhang Jigao disputed the term "fourth and a half" generation. In contrast, he suggested that the current international criteria to classify generations are more applicable.

 

He pointed out that single combat is rare in modern warfare, and that the majority of cases now involve system combat and network operations, so that the combat capabilities of a fighter depend on many factors. "This does not mean that the optimization of an aircraft's radar, avionics, and missile detection ranges are bound to improvements in operational performance."

 

Zhang Jigao added that further improvements to the performance of the J10 would focus on the aircraft's aerodynamic layout and mission systems, and the approach to maintenance. "Aircraft development requires constant optimization and improvement," he said, "and our modifications will be comprehensive rather than being confined to a specific area." (ends)

 

 

China Talks Up J-15, J-10B Fighters

Chief Designer Discusses J-15 Shipborne Aircraft's Performance Modifications

 

(Source: People's Daily Online; published Nov. 12, 2013)

 

On November 6th, the 5th media day of AVIC, Wang Yongqing, chief designer of J-15 revealed that special design features have been applied to the J-15 in accordance with its deployment on aircraft carriers, in order to achieve the special requirements of shipborne aircraft.

 

Wang Yongqing, chief designer of the J-15 shipborne aircraft, explained to the media that the J-15 shipborne aircraft series no. 555 was a very important machine, although it had attracted limited media attention.

 

The J-15 is China's first generation shipborne fighter, developed on the basis of the J-11. Particular attention has been given to the special requirements of shipborne aircraft, in addition to the guarantee of its combat capabilities.

 

"This means addressing issues of how to take off, land, maneuver and conduct maintenance on board the aircraft carrier." Wang Yongqing pointed out that there are tremendous differences in the way that shipborne aircraft take off and land on an aircraft carrier and on the ground. Correspondingly, there are considerable differences in the overall design of the J-15 compared to the J-11 series.

 

As China's first shipborne fighter, the J-15 has excellent sea-air combat capability, and is equipped with a variety of air-to-air, air-to-ground and air-to-sea attack weapons. Its comprehensive combat capability has reached an internationally advanced level which reflects the extraordinary technical achievements of China's aviation industry.

 

We can conclude from the appearance of J-15 that special features have been added to its front wings, aerodynamics, and wing area, and to its airframe equipment used in takeoff and landing.

 

The takeoff and landing equipment of the J-15 are more robust than that of the J-11 series. According to Wang Yongqing, this is because the forces experienced by a shipborne aircraft while landing on an aircraft carrier are 4 times those experienced during a ground landing. In addition, the J-15 shipborne aircraft is also equipped with hook arrestment gear for the purpose of landing on aircraft carriers.

Les premiers pilotes de l’aéronavale chinoise qualifiés sur porte-avions

04.07.2013 Helen Chachaty - journal-aviation.com

 

Selon une information du site internet du ministère chinois de la Défense, cinq pilotes et des officiers d’appontage ont reçu leur certification à la suite d’une campagne de qualification en mer du premier porte-avions de la marine chinoise, le Liaoning. Les pilotes ont effectué plusieurs manœuvres de décollage et d’appontage à bord des Shenyang J-15 de l’aéronavale durant les 25 jours qu’a duré l’entraînement.

 

Les premiers pilotes de l’aéronavale chinoise qualifiés sur porte-avions

Fin novembre 2012, la Chine annonçait que le premier appontage avait été avec succès sur le Liaoning, deux mois après avoir réceptionné le porte-avions, l’ex-Varyag racheté à l’Ukraine en 2000. En avril, le CEMM adjoint Song Xue avait laissé entendre que la Chine se doterait certainement d’un second porte-avions.

Le premier porte-avions chinois, le Liaoning, effectuera un voyage en haute mer avec des appareils embarqués

2013-05-15 CRI

 

Ces derniers jours, l'information selon laquelle le premier porte-avions chinois, baptisé Liaoning, est prêt à larguer les amarres pour un voyage en haute mer a fait l'objet de l'attention des différents milieux. Avec la création officielle de la première force aérienne embarquée, il y a des analyses qui estiment que la Chine est en train d'accélérer le perfectionnement de la formation du groupe de combat du porte-avions et que le voyage en haute mer du Liaoning est entré au compte au rebours. Selon des experts militaires chinois, le Liaoning entreprendra en forme de flotte son premier voyage en haute mer et le genre des avions embarqués mérite plus d'attention que leur nombre.

 

Récemment, une série de photos et images du porte-avions, de son port d'attache et de la base des avions embarqués, révélés par des médias, ont fait faire des conjectures au monde extérieur. Le Liaoning effectuerait son voyage en haute mer et la durée pourrait atteindre un mois. Même certains médias estiment que ce premier voyage en haute mer s'effecturait en forme d'une flotte. Et peu auparavant, le porte-parole du ministère chinois de la Défense, Yang Yujun, avait déclaré que le porte-avions ne doit pas rester toujours dans son port d'attache. Le commissaire politique de ce porte-avions, Mei Wen avait aussi révélé que ce dernier entreprendait son voyage en haute mer en cours d'année. Et maintenant avec la création de la force aérienne embarquée à bord de porte-avions et l'amélioration des conditions techniques, il semble que le premier voyage en haute mer du Liaoning commencera.

Le premier porte-avions chinois, le Liaoning, effectuera un voyage en haute mer avec des appareils embarqués

Le professeur Fang Bing de l'Université de la Défense de Chine a estimé que la principale tâche de ce voyage en haute mer est de tester les divers équipements embarqués à bord de porte-avions et de pratiquer des expériences de décollage et d'atterissage effectifs des chasseurs J-15 embarqués dans des conditions de mer complexes. Cette sorte d'expériences sera plus importante que les armements pour la marine chinoise. Ecoutons M. Fang Bing :

 

« Si le Liaoning entreprenait son voyage en haute mer, ses principales tâches seraient d'abord d'essais, puis de l'entraînement. Pour les essais, ils consistent à tester sur le terrain les équipements embarqués dont les armes, les radars et les sonars, ainsi que les différents systèmes embarqués pour connaître leurs performances réelles. En outre, des essais réels en haute mer de décollage et d'atterissage des chasseurs J-15 et d'autres appareils nous permettraient de connaître leurs résultats. Pour l'entraînement, il s'agit des exercices d'étude. On va étudier l'organisation des exercices de décollage et d'atterrissage des appareils en haute mer, la coopération et coordination entre le porte-avions et d'autres bâtiments de guerre en haute mer. Je pense que par ces exercices en haute mer, on pourrait accumuler des expériences qui sont, pour la marine chinoise, plus importantes que le porte-avions et les appareils. »

 

Tout le monde sait que le niveau des appareils embarqués sont le principal symbole du niveau des armements du porte-avions. La capacité de combat des appareils embarqués détermine directement l'efficacité de combat du groupe de combat du porte-avions. Selon l'expert militaire Fang Bing, le nombre d'avions embarqués à bord du porte-avions Liaoning pour son premier voyage en haute mer n'est pas une chose importante, ce qui mérite attention, c'est le genre d'appareils embarqués à bord de ce porte-parole.

 

« Le nombre d'avions embarqués à bord du porte-avions n'est pas important, c'est pace qu'il s'agit en effet du premier voyage en haute mer du porte-avions. Selon moi, ce qui est important, c'est que le porte-avions pourrait sortir avec tous les genres d'avions. Il y aurait non seulement des appareils aux ailes fixes, mais aussi des hélicoptères embarqués. Parmi les appareils aux ailes fixes, il y aurait des chasseurs J-15 et des avions d'entraînement. En outre, parmi les hélicoptères embarqués, en plus d'hélicoptères anti-sous-marains, y a-t-il d'autres types d'hélicoptères ? par exemple des hélicoptères de sauvetage et surtout des hélicoptère pré-alarme. Si tous les genres d'appareils pourraient être embarqués, les facteurs nécessaires du groupe de combat du futur porte-avions seront complets. En tout cas, je trouve que la variété des appareils est plus importante que le nombre des appareils. »

J-15 test 12

 

Nov. 27, 2012 defense-aerospace.com

(Source: China Daily; published Nov. 27, 2012)

 

Fighter Jets Successfully Land On Aircraft Carrier

 

China has moved closer to its goal of building a blue-water navy, with pilots successfully landing on and taking off from the Liaoning, the country's first aircraft carrier, according to military experts.

 

Dai Mingmeng, a squadron leader from an aviation regiment of the East China Sea Fleet, landed a J-15 carrier-based fighter jet on the Liaoning on Friday morning, marking a milestone for the People's Liberation Army navy, according to the Beijing-based Mirror Evening News.

 

Following Dai, another four pilots also landed J-15s on the carrier and later took off, the PLA Daily reported on Sunday.

 

"This is a new landmark in the Chinese navy's efforts to develop the combat capability of its carrier battle group," Du Wenlong, a senior researcher at the PLA Academy of Military Science, said on Sunday.

 

"The carrier-borne fighter jet is the core of a carrier battle group and the success of landing and take-off tests is of unparalleled importance as pilots further their training," he said, adding that the successful exercises indicate the Liaoning and the J-15 have met the navy's requirements.

 

"It also proves that our personnel training system for the aircraft carrier is successful."

 

Xu Yongling, a former test pilot and military aviation expert, said: "The landing operation is totally up to the pilot's manual manipulation of the aircraft. Together with the risks of the whole landing process, it is far more difficult than performing an outer space mission.

 

"The achievement and significance of the first landing on the carrier is equivalent to a breakthrough in aerospace exploration," he said.

 

China Central Television broadcast footage of the landing and take-off on Sunday. It showed a J-15, which took off from an airport in an unidentified location, approaching the Liaoning.

 

The pilot then lowered the tailhook, a hook attached to the rear of the plane and used to rapidly decelerate during landings, and engaged the second arresting cable. The J-15 taxied about 50 meters and stopped.

 

The plane folded its wings and technical checks were made. After take-off preparations were complete, the pilot restarted the engines and flew off the deck.

 

According to Southern Metropolis Daily, the earliest landing test that was disclosed on the Internet took place on Nov 20 when a J-15 landed on the Liaoning. Details about the earlier test remain unknown.

 

Advanced jet unveiled

 

The Liaoning, a refitted Soviet-era carrier, entered active service in September and is now in the middle of its second sea trial after joining the navy.

 

Since being commissioned to the PLA navy, its crew has completed more than 100 training and test programs, according to Xinhua News Agency.

 

Earlier this month, reports and photos appeared on the PLA Daily and the website of the Defense Ministry stated that the Liaoning successfully completed a touch-and-go test on Oct 29. The reports did not disclose which aircraft carried out the test and how many jets were involved in the operation.

 

However, according to military observers, it was conducted by a J-15 fighter jet.

 

The news of the landing test also marked the debut of the J-15 as China's first generation multi-purpose carrier-borne fighter jet, the PLA navy said.

 

It has been given an official nickname - Flying Shark.

 

According to aviation fans and Western media reports, the twin-engine J-15 was developed by Shenyang Aircraft Corp, a subsidiary of the Aviation Industry Corp of China, and at least 12 prototypes have been manufactured and used in tests.

 

Xinhua said the J-15 is able to carry anti-ship, air-to-air and air-to-ground missiles and precision guided bombs. It quoted military experts as saying the J-15 has comprehensive capabilities comparable to those of Russia's Sukhoi Su-33 and the US F/A-18 Hornet.

 

Although it was developed based on the Su-33, the avionics and weaponry on the J-15 are more advanced than those of the Su-33, and the jet features domestically developed, cutting-edge technologies, such as an active electronically scanned array radar, radar absorbent material and an infra-red search and track system, military experts said.

 

The J-15 "likely exceeds or matches the aerodynamic capabilities of virtually all fighter aircraft currently operated by regional militaries, with the exception of the US' F-22 Raptor", according to Gabe Collins, a China observer in the US, and Andrew Erickson, professor at the US Naval War College, in an article on their website, chinasignpost.com.

 

The J-15 is particularly good in an aerial dogfight, due to its maneuverability and high thrust-to-weight ratio, said Kanwa Defense Review, a Canadian online magazine on defense affairs and weapon technology.

 

In addition to the advanced jet, the landing also cast the limelight on the arresting gear on the Liaoning, which is one of the most sophisticated mechanical instruments on aircraft carriers.

 

Only a handful of nations have the technology and ability to develop and manufacture arresting gear and none of them will export such technology to other countries, defense industry insiders said, noting that the situation left China no other choice but to develop the equipment itself.

 

More time needed

 

In spite of great success, the completion of the landing and take-off tests is only a small step toward the Chinese aircraft carrier's fully possessing combat capability, experts said.

 

"The tests were carried out in daytime and under relatively simple circumstances," Du Wenlong said. "Our pilots haven't performed landing and take-offs at night or in complicated situations, and they will need more training on how to intercept enemy aircraft and destroy targets at sea."

 

"Considering the experiences of other countries, I think we have to wait at least two years before our carrier-based fighter jets become fully operational," said Zhang Junshe, a researcher from the Naval Military Studies Research Institute.

 

"And taking the time needed to provide training for other planes, such as airborne warning and control system aircraft, and anti-submarine aircraft, into account, it will take four to five years for our carrier to obtain full combat capability."

 

The J-15 fighter jets will begin to conduct combat and formation drills only after other aircrafts complete landing and take-off training, he added.

 

To become a pilot for a carrier-based fighter jet, a PLA aviator has to pass four rounds of tests, said Zhang Hongtao, a senior officer of the PLA navy who is in charge of selecting pilots.

 

The selected pilots must be under 35 years old and have at least 1,000 flight hours, he said, adding that they also must possess a strong mind and have quick responses.

 

"A pilot in the US Navy usually spends at least 21 months in training before he is deemed qualified to perform duties on an aircraft carrier. I don't think we can do it in less time," Du said.

 

"A take-off process alone requires 65 actions by our flight deck personnel and each step cannot allow any error," said Li Xiaoyong, deputy chief of the aviation section on the Liaoning.

 

"Although this work is arduous and dangerous, none of us has shown cowardice, for we are 'super warriors' on the carrier."

 

"After the landing and take-off tests, those who once looked down on China's capabilities can no longer call it (the Liaoning) a shark without teeth," said Chen Bing, a news commentator.

2011-07-16(China Military News cited from the-diplomat.com and written by David Axe)

 

The People's Liberation Army Navy has finally broken the silence about its new carrier-based jet fighter, the J-15. While outside observers have strongly suspected for several years that China intended to deploy the J-15 – an adaptation of the Russian Su-33 – aboard the PLAN's first aircraft carrier Shi Lang, Chinese officials didn’t confirm it until last week.

 

Confirmation of the J-15 came with some revealing details about the plane's missions and limitations. It’s clearer than ever that the J-15 will inherit most of the Su-33’s limitations, particularly with regard to payload and range. As a result, Shi Lang could be highly vulnerable to foreign naval forces in combat.

 

Unnamed ‘Chinese aviation officials’ said that three J-15 prototypes would begin testing this year, and that the last of them would have all the features of the planned operational version, including folding wings to allow more compact storage aboard Shi Lang, a refurbished Soviet vessel that displaces just two-thirds as much as a US flattop.

 

Shi Langdoesn’t have the steam catapults that US and French carriers use to launch aircraft. Instead, the Chinese ship, like its Russian sister ship Kuznetsov, uses an elevated ramp to help boost planes into the air. Ramp-launch, while less complex than a catapult, doesn’t impart the same amount of energy. That means ramp-launched fighters must be relatively light. The British Harrier, which used a ramp, weighed just 7 tonnes empty. The Su-33 weighs 20 tons empty.

 

In Russian service, the Su-33 has been restricted to short-range patrols carrying just a few air-to-air missiles. That's the big reason why the Kuznetsov has never had a major impact on the European naval balance.

 

Shi Langwill be similarly handicapped, more so because the Chinese intend the J-15 to carry the C-602 anti-ship cruise missile. Carrying a single one-tonne C-602, the J-15 will have an operational range of just 250 miles, according to the anonymous industry officials. It’s not clear if the J-15 will be able to carry air-to-air missiles for self-protection, in addition to the C-602.

 

If the Chinese military operated a large number of effective aerial tankers, the J-15's payload limitation would be more manageable. Even catapult-launched fighters, such as the US F/A-18E/F, can range just 400 miles from their carrier with useful combat load. But aerial refueling can extend that range to more than 1,000 miles. F/A-18s routinely fly missions over Afghanistan from carriers operating in the Indian Ocean.

 

If Shi Lang is meant to operate in a sea control role, clearing the ocean of enemy vessels, then it could find itself at a disadvantage compared to rival naval forces. The C-602 has a range of around 250 miles. So a Chinese carrier battle group could strike surface targets at a distance of 500 miles.

 

A US carrier group launching F-18s armed with Harpoon anti-ship missiles could strike from a distance of at least 600 miles. Factor in aerial refueling – and the fact that the Harpoon is light enough for a single F-18 to carry two – and the US advantage increases dramatically. The Su-33 is simply not an ideal fighter for ramp-equipped carriers.

 

It’s telling that within a few years, the Chinese will be the only country operating Su-33s or its derivatives from carriers. The Russians decided to replace the Su-33 with a version of the much smaller MiG-29 after realizing that the MiG had similar performance, but Kuznetsov could carry many more of them. The Indians, too, are buying a MiG-29 variant to replace their Harriers.

 

Future Chinese carriers could include a catapult. Indeed, the likelihood that carriers after Shi Lang will be catapult-equipped is sure to increase, once the PLAN sees firsthand how limited its J-15s really are.
