Company Sikorsky, develops heavy CH-53K helicopter for the U.S. Marine Corps, has transferred to the assembly flow its first layout for ground tests GTV (Ground Test Vehicle). GTV will be built after the four year old standard (Engineering Development Model), which rise up into the air in 2014-15.
«The main goal is to verify GTV dynamical systems CH-53K helicopter by painstaking testing and determining the efficiency of the rotor blades, boxes and engines when the car is tied to the land,» said Michael Torok (Michael Torok), vice president of programs from CH- 53K. «Extensive ground tests should confirm the data properties of dynamical systems, and hydraulic and electronic systems and avionics requirements of the Marine Corps helicopter languid to the next generation.»
New helicopters should change CH-53E Super Stallion, since 2019. Payload CH-53K on the outer suspension will increase to more than 27,000 pounds at a distance of more than 110 nautical miles. Development includes growth-duty engines GE38-1B power 7500 hp, broken torque transmission, which is more excellent distribute engine power to the main rotor blades of composite fourth-generation growth lift and fuselage made of composite materials.
On the main plant in Stratford (Connecticut pcs) conducted ground test airframe for structural testing. The main section of the fuselage supply Aurora Flight Sciences, ITT Excelis, GKN Aerospace and Spirit Aerosystems.
Assembly line layout is at a plant in West Palm Beach. Ground and flight tests will be conducted in the Flight Research Center in the same city in Florida.
