Environmental control and electric power are provided for a vehicle (12) carrying at least one gas turbine engine (14, 16) including a turbine (40,46) and a compressor (42,48); a stored energy device (28); a first turbine (64) powered by the stored energy device (28); an expansion turbine (60) for a

Environmental control and electric power are provided for a vehicle (12) carrying at least one gas turbine engine (14, 16) including a turbine (40,46) and a compressor (42,48); a stored energy device (28); a first turbine (64) powered by the stored energy device (28); an expansion turbine (60) for an air cooling cycle; and an electric generator (34) rotatably driven by the first turbine (64) and the expansion turbine (60). The electric generator (34) has a minimum operating speed required to generate acceptable electric power for the vehicle (12). The environmental control and electric power for the vehicle (12) are provided by a method including the steps of normally rotating the expansion turbine (60) with bleed air from the compressor (42,48) of the at least one gas turbine engine (14, 16) to generate temperature conditioned, pressurized air for the environmental control of the vehicle; driving the electric generator (34) above the minimum speed with the expansion turbine (60) to provide electric power for the vehicle (12); and, in the absence of sufficient power from the expansion turbine (60), maintaining the electric generator (34) above the minimum speed by powering the first turbine (64) with the stored energy device (28) to provide electric power for the vehicle (12).

[ What is claimed is:] [1.]1. A method of providing environmental control and electric power for a vehicle carrying a stored energy device, an electric generator, and at least one gas turbine engine having a turbine and a compressor, the electric generator having a minimum operating speed required to generate acceptable electric power for the vehicle, the method comprising the steps of:normally expanding bleed air from said compressor of said at least one gas turbine engine to generate a) temperature conditioned, pressurized air for the environmental control of said vehicle, and b) rotational energy;driving said electric generator above said minimum speed with said rotational energy from said bleed air to provide electric power for the vehicle;in the absence of sufficient rotational energy from said bleed air, activating said stored energy device while said generator is still rotating above said minimum operating speed from said rotational energy; andmaintaining said generator above said minimum operating speed with rotational energy generated from said stored energy device to provide electric power for the vehicle.
