The invention is a multi role primary/auxiliary power system with engine start capability for aircraft that provides electric, mechanical and air conditioning power as well as engine starting functions. The compressor (20), turbine (26) and motor/generator (24) are coupled to a drive shaft (14) of the aircraft\s engine (12) with the motor/generator (24) mounted between the compressor (20) and turbine (26). A first clutch (28) is mounted on the drive shaft (14) between the motor/generator (24) and the turbine (26). Coupled to the outlet (29) of the compressor (20) is a two-way valve (34) adapted to couple the compressor (20) to either a first duct (36) or second duct (37). Both of these ducts (36), (37) are coupled at their opposite ends to the turbine (26). Mounted in the first duct (36) is a combustor (40) and in the second duct (37) a first heat exchanger (42). A third duct (44) is also coupled between the compressor (20) and the turbine (26) and which incorporates a valve (50). Mounted between the turbine (26) and the engine (12) is a gear reduction assembly (58). Coupled to the output of the turbine (26) is a fourth duct (100) which is coupled to a second two-way valve. The second two-way valve (102) either couples the fourth duct (100) to an overboard vent (104) or a fifth duct (106), having a heat exchanger (108) mounted therein to the cabin of the aircraft. Coupling the first, second and third ducts (36), (37), and (44) together is a bypass duct (110) (sixth duct) which bypasses the turbine (26) and connects to the fourth duct (100). The sixth duct (110) also incorporates a simple open/close valve (112). Finally, a control circuit (115) for the motor/generator is provided which can couple either onboard battery power or ground supply AC power to the motor/generator.
