Abstract
A gas turbine powerplant which has two compressor parts alternatively connectable: 1. in series for supersonic flight, or, 2. in parallel for subsonic flight and particularly useful at take-off. The compressor parts are co-axial and a valve extends obliquely between them having two positions corresponding to the two alternatives above. In the first position the valve allows series flow and in the second position its obliquity deflects the delivery of the first compressor part out into a bypass duct and allows ambient air into the second compressor part.
