V/STOL Aircraft Engine and Mechanical Drive Component Integration

V/STOL aircraft propulsion systems are required to provide vertical lift, horizontal thrust, attitude control, and distribution of power for engine-out cases with high efficiency, low weight, and high reliability. These V/STOL requirements have been converted into specific design objectives for mechanical drive components including the gears, bearings, clutches, and shafting that interconnect the engines, lift and propulsion fans, and rotors in various V/STOL aircraft defined in recent system studies.
