V-22 Osprey visited Cessna Aircraft in Wichita, Kansas. March, 2013.
The Osprey is an interesting flying machine. According to Wikipedia: "The V-22's two Rolls-Royce AE 1107C engines are connected by drive shafts to a common central gearbox so that one engine can power both proprotors if an engine failure occurs.
"A transmission interconnect shaft provides single-engine operation. The thermal signature of the aircraft is minimised with an AiResearch infrared emission suppression unit, installed on the nacelles near the engine exhaust."
"The entire rotor, transmission and engine nacelles tilt through 90° in forward rotation and are directed forwards for forward flight, and through 7° 30' in aft rotation for vertical take-off and landing."
