The propulsion system of the V-22 Osprey, comprising the drive system, the power plant installation, and the proprotor, is a unique design driven by the operational requirements of this tiltrotor aircraft. The drive system, which includes five gearboxes, shafting, and special nonlubricated flexible couplings, is described. The rationale for arrangement and lessons learned is followed by a discussion of the effect of special requirements such as shipboard compatibility and cooling. Lubrication system operation from horizontal to vertical modes, operation over a wide range of engine speeds, and altitudes from sea level to 6000 m are substantial design considerations. The development testing is also described. The power plant is the Allison T406 two-spool version of the T56 series engine rated at 4550 kW (6100 hp), which is designed to operate from horizontal to vertical positions at each wing tip. The power plant installation, including air induction, engine mounting, fly-by-wire controls, fuel system, and secondary power, is described. The rotor system design is driven by the wide range collective pitch control required to achieve tiltrotor flight and the need for aeroelastic stability with a mechanically simple system. Rotor system material and construction, component design, blade folding, development problems, and testing are discussed.
