Abstract
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 firs…
