ROTARY GAS TURBINE ENGINE Russian patent published in 2017 - IPC F02C3/16 

FIELD: engines and pumps.

SUBSTANCE: rotary gas turbine engine contains a centrifugal impeller with centrifugal channels rigidly mounted on the shaft, which compresses the oxidizing working fluid supplied to it, installed in a toroidal combustion chamber coaxial with it, tangentially located on it nozzles, providing creation of a reactive force pulse from flowing through nozzles combustion products of the mixture of inflammable and oxidizing working fluid for impeller and combustion chamber rotation, means for supplying inflammable working fluid and means of ignition of the mixture of inflammable and oxidizing working fluid. The internal cavity of the combustion chamber housing is divided into individual combustion chambers by rigidly fixed transverse partitions, which are a continuation of the impeller blades, and fixed to form the inlet openings into separate combustion chambers. The outlet openings of the centrifugal channels are open in the cavity of the individual combustion chambers through the inlet openings. At least one outlet of the centrifugal channel is open to the cavity of each individual combustion chamber provided with at least one nozzle made supersonic in the form of a round or flat Laval nozzle. The central axis of the nozzle at its inlet coincides in direction with the central axis of the individual combustion chamber at its outlet. Separate combustion chambers are provided with means for supplying the inflammable working fluid and with ignition means located in each transverse partition and allowing simultaneous ignition of the mixture of inflammable and oxidizing working fluid in adjacent combustion chambers adjacent to each other. Between the centrifugal impeller and individual combustion chambers, a throttling means is provided to provide the desired flow and thermodynamic parameters of the compressed streams of the oxidizing working fluid at the inlet to each individual combustion chamber.

EFFECT: increased efficiency and reliability of the rotary gas turbine engine by organizing a sustainable and efficient burning of the fuel-air mixture.
