Claims (1)

The invention relates to energy, in particular to a method of converting thermal energy into mechanical energy in a gas turbine engine and a gas turbine engine that implements this method and is aimed at reducing losses at the entrance to the combustion chamber and increasing efficiency and power density. Before entering the rotating combustion chamber, the working fluid is compressed and twisted relative to the axis of the gas turbine engine, heated in the combustion chamber, expanded at the exit from it and fed to the turbine for further expansion in it. The working fluid is twisted relative to the axis of the gas turbine engine prior to the output of the combustion chamber before being fed into the turbine, while the directions of the twist at the inlet and outlet of the combustion chamber are opposite. The gas turbine engine has a combustion chamber installed with the possibility of rotation relative to the turbine, having an inlet and an outlet and a plurality of internal profiled channels formed by a plurality of walls, forming nozzles extending the working fluid at the outlet of the combustion chamber and located at the outlet of the combustion chamber with the angle of inclination α on the plane of the sweep the combustion chamber relative to the line (O - O) of the intersection of the plane drawn through the longitudinal axis of the engine with the sweep plane up to 150 ^o . At the entrance of the combustion chamber, the angle b of the inclination of the projections of the walls of the profiled channels onto the sweep plane of the combustion chamber relative to the line (O - O) of the intersection of the plane through the longitudinal axis of the engine with the sweep plane ranges from 0 to 75 ^o .
