GAS TURBINE ENGINE WITH TWO INJECTOR BLOCKS Russian patent published in 2023 - IPC F02C5/12 

FIELD: gas turbine engine.

SUBSTANCE: gas turbine engine with two blocks of nozzles includes a cylindrical body with inlet and outlet windows, in the cavity of which a turbine wheel is installed, along the circumference of which there are radial blades. There are skirts on the sides of the wheel, which are in contact with the removable turbine walls. Between the removable turbine walls and the removable walls of the housing, two cavities are formed in which compressor discs with blades located around the circumference of the disks are installed. The compressor disc bushings and the turbine wheel bushing are rigidly fixed to the turbine shaft. The compressor cavities communicate through radial holes with longitudinal windows made in the circumferential walls of the housing and in the removable walls of the housing. The blocks with injectors are placed outside the engine housing and connected to the engine body by means of guide pipes, the ends of which are equipped with flanges, one end is rigidly attached to the base of the injector block, and the other end is rigidly attached with flanges to the engine body. The guide pipes of both blocks are installed at an angle of 90 degrees to the plane of the turbine blades. The closed combustion chambers in each block with nozzles include the cavities of the blocks, the cavities of the guide pipes and the cavities between the turbine wheel blades. The intake pipe is attached to the engine body from the outside by means of flanges made along the pipe, and to the side wall of the injector block by flanges made on the transition cavity.

EFFECT: simplifying the design, reducing the size, increasing reliability, increasing power and obtaining a closed combustion chamber.
