COMBINED PULSATING DETONATION OUTPUT DEVICE OF TURBOJET BYPASS GAS TURBINE ENGINE WITH FUEL SUPPLY TO EXTERNAL CIRCUIT Russian patent published in 2024 - IPC F02K7/04 F02K3/11 

FIELD: engine building.

SUBSTANCE: invention can be used for engines with a second circuit without a mixing chamber used in power plants of subsonic aircraft. Technical problem solved by the claimed invention consists in improvement of efficiency. Said problem is solved in bypass turbojet combined pulsating detonation output device with separate external and internal circuits, containing in the internal circuit a converging sound nozzle, and in the outer circuit in the area of the outlet section with a gap between the outer and inner walls of the outer circuit there is a two-dimensional gas-dynamic resonator made in the form of an annular element with a resonator cavity, which traction wall is made in the form of a torus dissected in the cross section, at the same time annular projections are formed on the outer and inner walls of the outer contour, forming an annular gap with the corresponding outer and inner edges of the resonator cavity of the two-dimensional gas-dynamic resonator, besides, it comprises fuel manifold with nozzles to feed additional fuel into flow ahead of its inlet via annular nozzle into two-dimensional gas-dynamic resonator.

EFFECT: higher thrust.
