Acquisition: V-22 Osprey Hydraulic System

Abstract : The V-22 Osprey Joint Advanced Vertical Aircraft (the V-22) is a tiltrotor vertical takeoff and landing aircraft which was developed to fulfill multi-Service operational requirements. The V-22 design incorporates advanced technologies in composite materials digital avionics fly-by-wire controls and survivability. It operates as a helicopter for takeoffs and landings and once airborne converts to a turboprop aircraft for distance flight. That conversion capability is accomplished through the tilting or rotation of a nacelle mounted at the end of each wing. Each nacelle is equipped with an engine and transmission that drives a rotor with a diameter of 38 feet. The V-22 hydraulic system which comprises three independent subsystems provides hydraulic power to the V-22 rotor system controls and control surfaces.
