Pict 4 of 6 The Sikorsky S-64 Skycrane is an American twin-engine heavy-lift helicopter. It is the civil version of the US Army's CH-54 Tarhe. Originally a Sikorsky Aircraft product, the type certificate and manufacturing rights were purchased from them by Erickson Air-Crane in 1992.
Sikorsky Aircraft Corp., a subsidiary of United Technologies Corp. (NYSE: UTX), has powered up the engines and spun the rotor head on the first prototype CH-53K heavy lift helicopter -- designated the Ground Test Vehicle (GTV). The January 24 event continues the "Bare Head Light Off" phase of testing -- so named because it was conducted without rotor blades -- that began under auxiliary power in December with safety-of-flight test pilots at the aircraft's controls.
