“GTV main engines powered ‘on’ is a significant step for the CH-53K helicopter program,” said Mike Torok, Sikorsky’s CH-53K Program Vice President. “Having independently tested the aircraft’s many components and subsystems, including electrical and avionics, hydraulics and flight controls, landing gear, propulsion, transmissions and rotors, now we have begun testing these critical functions as an entire system powered by the GTV aircraft’s three GE 7,500 shaft horsepower class engines.”

Sikorsky delivered the GTV into the test program at the company’s West Palm Beach, Fla.-based Development Flight Center in late 2012. Now anchored to the ground at its remote outdoor test site, the 44,000-pound GTV aircraft is outfitted at more than 1,300 points with sensors that will measure and verify the ability to operate safely under its own power. The GTV will undergo ground testing for approximately two years with both Sikorsky and U.S. Marine Corps test pilots at the controls.
