ABSTRACT:
Standard aircraft engine accessories like generators, alternators, fuel pumps, vacuum pumps, or air pumps are dually mounted on compact, remotely operable clutch members flanged to standard engine mounting pads for direct engine drive. The clutch member includes complementary mounting pads for such engine mount and has a throughbore for rotatably supporting a pair of journaled shafts respectively carrying, driving and drive clutch plates and power operating means for longitudinally shifting one of the plates to engage the other. One shaft includes a connection for a spool-type safety coupling to drive a spline shaft extending beyond the engine mounting pad to engage an engine driven gear. The other shaft includes complementary connection for a spool-type safety coupling for driving the engine accessory. The clutch body may be used for mounting any (or all) engine accessory power unit or used solely for mounting stand-by or auxiliary (duplicate) power units that need not be run until commanded to do so, either during pre-flight check-out or to replace a non-functioning power unit during flight. The compact, lightweight clutch member, needs no revision of aircraft or engine structure to provide reliable back-up functions for continued operation of an engine during flight without interconnection to other engines or external power sources for such functions (e.g. electrical power). The clutch unit greatly improves both operability and reliability of an aircraft engine during flight. Further, it substantially enhances the safety of air flight, especially in single engine aircraft.
