ABSTRACT:
A gas turbine engine for aircraft. A generator, which undertakes to supply energy for auxiliary devices, is spaced between a compressor and a turbine. A heat exchanger which surrounds the generator housing, and through which compressor air and fuel flow, is provided for cooling the generator. The compressor air which is cooled by the fuel is supplied to the rotor of the generator, and possibly to a bearing of the rotor shaft.
