TANGENTIAL COMBUSTION CHAMBER WITH VANELESS TURBINE FOR GAS TURBINE ENGINE Russian patent published in 2017 - IPC F23R3/06 

FIELD: engines and pumps.

SUBSTANCE: annular combustion chamber for a gas turbine engine is designed with an outer casing, the inner casing, the front wall and the grooves which are spaced apart circumferentially and formed with one or both of the inner casing and / or the outer casing and twisted around the center line of the engine in the longitudinal direction and spaced around the nozzle in the outer casing. The front wall connects the outer casing with the inner casing forming an annular space. The grooves are positioned downstream of the nozzles. The nozzles are designed to inject fuel and air into the annular space and direct the flow into the combustion chamber cavity in the direction with the explicit tangential velocity component. The grooves are designed to whirl and accelerate the hot gases reaching the optimal speed in contact with the turbine entrance.

EFFECT: optimal conditions for the combustion, reducing emissions of nitrogen oxide and carbon monoxide, increasing the cooling efficiency.
