Model 347![]() |
Major modifications included a fuselage stretch of 110", an aft pylon extended upward 30" to increase the distance between rotor planes (thus reducing noise levels), 4 blade duel rotor system, retractable landing gears, and hydraulically actuated wings, permitting incidence control throughout the aircraft's flight envelope. On May 27, 1970, the Model 347 lifted off on it's first flight at the Vertol Division's Center 3 Flight Test Facility at Eddystone, Pennsylvania. |
Following completion of it's test program, the Model 347 was retired from service and donated to the Army Aviation Museum, where she rest today. |
