ABSTRACT:
A jet propulsion engine such as a gas turbine engine has an air compressor for supplying compressed air to the engine compressor stages. The air compressor is controllably and selectively driven by way of a disconnectable drive connection between the air compressor and a freely rotatable fan which is arranged in front of the air compressor and which in operation is rotated by the flow of intake air into the engine. A by-pass duct permits a part of the intake air to be by-passed around the air compressor and passed in variable proportions either to the engine compressor stages or directly out of a by-pass duct outlet.
