ABSTRACT:
Improvements in a gas generator having a "rambine" rotor on which compression, combustion and expansion take place. The improvements include a counter rotating compressor rotor with blades shaped to impart a component of velocity in the direction of rotation of the compressor rotor, hence increasing the whirl velocity of inlet air to the rambine rotor.
Preferred embodiments include a plurality of compressor rotors for successively increasing the relative whirl velocity; a rambine rotor having a combustion zone with increasing cross-sectional area over an ignition delay distance for obtaining higher heat release using a weaker shock wave; a zero work rotor with sets of blades spaced by an annular combustion chamber; an ignition stabilizer and starting nozzle arrangement, and apparatus for controlling the gas generator over a range of power settings.
