| In January 2014, Sikorsky powered 'on' the three GE 7,500 shaft horsepower class engines of the first CH-53K heavy lift helicopter prototype - known as the Ground Test Vehicle - and spun the rotor head without rotor blades. The event continues safety-of-flight tests started in December with pilots at the aircraft's controls. The Ground Test Vehicle is anchored to the ground at Sikorsky's West Palm Beach, Development Flight Center in Florida. Four additional test aircraft are being prepared for flight test, beginning in late 2014. (PRNewsFoto/Sikorsky Aircraft Corporation) |
