The first prototype of the CH-53K transport helicopter that Sikorsky is building for the U.S. Marine Corps took off on its debut flight at the company’s facility in Florida on Oct. 27. Sikorsky is building 200 CH-53Ks at a total cost of up to $23 billion to replace the Marines’ depleted force of around 150 CH-53E transports, which do the heavy aerial lifting for the Marines’ combat battalions. The triple-engine, seven-blade CH-53K will be, by far, the West’s most powerful helicopter, able to haul 18 tons of external cargo 110 miles — twice as much as the CH-53E can carry.

Washington DC - The US Navy’s acquisition chief expects the Sikorsky CH-53K King Stallion to take its first flight this fall, placing the long-awaited milestone somewhere between now and November.


The super-heavy-lift helicopter for the Marine Corps has seen its share of technical troubles and delays, but the navy is still targeting an initial operational capability date of 2019.

The aircraft, which began development in 2006, was meant to be approved for “Milestone C” low-rate initial production and deployment in 2012, but the target was revised to 2016 due to budgeting and development issues with further postponements likely unless the first CH-53K can get off the ground this year.

“Right now we’re looking towards first flight of that aircraft this fall,” Sean Stackley, navy assistant secretary for research, development and acquisition, said at a Navy League forum 9 September.

March 11, 2015 by Donaldson Company - army-technology.com


Donaldson Aerospace & Defense has completed delivering system development versions of its engine air particle protection system (EAPPS) to Sikorsky Aircraft Corporation's CH-53K program that will provide the next-generation heavy-lift helicopter for the US Marine Corps.


The 12 Engineering Development Models delivered by Donaldson Aerospace & Defense, a division of Donaldson Company, Inc, support the system development and demonstration phase of the CH-53K programme.


This phase is scheduled to achieve a key milestone this month when the CH-53K ground test vehicle 'lights off' to test its three turbine engines, main and tail rotors and transmissions at Sikorsky's West Palm Beach, Florida facility.


The first flight is scheduled for 2014, with initial operating capability of the first CH-53K squadrons targeted for the Fiscal Year 2019.


The Marine Corps plan to acquire 196 CH-53Ks, which are designed to have twice the payload and combat radius capability of the current heavy-lift CH-53E, and perform better in 'high and hot' operating conditions, all while maintaining the same footprint as the CH-53E when deployed on ships.


In addition to flying at high altitudes in hot temperatures, the CH-53K will carry troops and cargo to remote, unimproved landing sites in dusty and dirty conditions.


Its three, 6,000-shaft-horsepower-class engines are key to achieving these goals and Donaldson's EAPPS are necessary to ensure the engines perform safely and reliably in such challenging conditions.


Donaldson Aerospace & Defense general manager Mark Rigby said: "The CH-53K will provide critical heavy-lift capabilities for the most urgent missions the Marines perform, including combat deployment and support, troop positioning, and resupply and humanitarian relief after natural disasters.


"Donaldson is honored that our advanced filtration technology will play an essential role in this impressive helicopter's success on those missions."


Using its patented Strata™ Tube technology, Donaldson developed the lightweight, high-efficiency EAPPS to protect the CH-53K's engines from the damaging effects of dirt, dust, sand, and other contaminants.


Strata technology offers low airflow restriction, high filtration efficiencies and minimal maintenance. Strata panels are used successfully in many military applications, including the D and E versions of the CH-53.

Sikorsky tests structural strength of new helicopter

April 11, 2014 By Richard Tomkins (UPI)


The CH-53K helicopter being developed by Sikorsky Aircraft undergoes the Static Article Test to verify its structural strength


STRATFORD, Conn. -- An initial series of tests to verify the structural strength of the new CH-53K Super Stallion helicopter have successfully been completed by Sikorsky Aircraft.


The tests, required by the U.S. Naval Air Systems, were conducted using a full-size, non-flying airframe called the Static Test Article.


"The Static Test Article will enable Sikorsky to replicate the many stresses, strains and aerodynamic forces the CH-53K helicopter will experience during all aspects of flight, whether the aircraft is empty, filled with cargo, or carrying up to 36,000 pounds of gear suspended beneath the aircraft by an external sling," said Mike Torok, Sikorsky's CH-53K program vice president.


"By placing incrementally heavier static loads on various parts of the airframe assembly -- including those well beyond the airframe's analytical design strength -- we can measure structural integrity, airworthiness and crash worthiness, and verify safety margins for all expected operational conditions," Torok said.


"The Static Test Article is composed of the cockpit, cabin, fuel sponsons, a transition section and the tail rotor pylon -- all suspended off the ground by the shaft of the aircraft’s main rotor gearbox. Surrounding support beams hold the numerous hydraulic cylinders that apply the flight and inertial loads to parts of the airframe assembly,” Sikorsky said.


Component-representative weights that simulate the presence of the engines and landing gear are also part of the configuration.


Six tests have been performed to date and testing will continue for another two years, the company said.


The CH-53K is a heavy-lift aircraft with a cruise speed of 196 miles per hour and a combat radius of 110 miles. The U.S. Marine Corps plans to procure some 200 CH-53Ks, which are expected to become operational in 2018.

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.

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."

Sikorsky Receives U.S. Navy Award to Build Four CH-53K Operational Test Helicopters

June 06, 2013 sikorsky.com


  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.
