An aircraft cabin is climatized by tapping air from the engine compressors and feeding it into the cabin through a loop which includes a compressor, a cooling turbine driving the compressor, and several cooling stages. A second loop, using preferably helium, includes a second compressor and a second turbine, the second compressor being driven by both turbines, and the cooled helium is in heat exchange with another cooling loop which runs through instrument compartments. Discharged cabin air is used to precool the compressed helium.

Climatizing of aircraft

A gear box is provided with three inputs mutually decoupling each other so that neither can drive the other two via the gear box but either can drive secondary power sources such as a pump and a generator. The three inputs are respectively connected to an aircraft engine shaft, a starter-air turbine and a gas turbine, whereby additionally the starter turbine is connected to drive the shaft for starting but not vice versa. The air turbine receives air from the compressor of the gas turbine or otherwise. The shaft can be disconnected from the system.
