ABSTRACT:
The present device is a rotor having a plurality of rotor chambers formed integral therewith. Each chamber has an inlet opening into a main section, whose sidewalls are substantially parallel, and further has a nozzle section whose sidewalls deviate at an angle from the main section sidewalls to create a sharp cross-sectional constriction and which nozzle section ends in an outlet opening. The present rotor is used as the single rotor of a turbine engine which has means to initiate a shock wave at the opening of the main section of each rotor chamber. The rotor chamber is formed to direct the shock wave uninhibited toward said outlet opening but said shock wave is reflected from said sharp cross-sectional constriction toward said inlet opening thereby compressing the gases in said chamber to a high pressure. In each chamber when said high pressure gases expand through said nozzle section the ensuing reaction drives said rotor.
