ABSTRACT:
A moveable, ovoid body for incorporation in and with the conventional elements of a turbo jet and possessing compressor and diffuser shape characteristics that are found in turbo jet machines. The invention is designed to take the place of conventional diffusers which are employed in both compressor and turbine stages of turbojets. When used with the hydrovapor engine, developed by the inventor, the moveable diffuser shell which operates in conjunction with impeller and turbine propeller blades offers a wide range of selectable operational parameters such as inlet flow velocity, compression chamber pressure and exhaust velocity.
