Aircraft with disengageable engine and auxiliary power unit components

摘要: Several improvements to an aircraft turbine engine and Auxiliary Power Unit (APU) are disclosed, as well methods of using these in routine emergency operations. The comprise the addition cockpit-controllable clutches that can be used independently disconnect engine's integrated drive generator (IDG), driven pump (EDP), fuel pump, oil from gearbox. These components may then connected air turbines by use additional powered turbines. Similar arrangements provided for APU components. Cranking pads, attached various components, disclosed provide a means externally powering testing purposes assist with start. Detailed new ground-testing maintenance enhancement flight safety, minimization component damage, extension engine-out flying range case in-flight shutdown.
