ADJUSTABLE PULSATIVE GAS DYNAMIC DETONATION RESONATOR OUTPUT DEVICE FOR DRAW PRODUCTION Russian patent published in 2019 - IPC F02K7/04 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to design of traction devices with resonant combustion chambers. Adjustable pulsing gas-dynamic detonation resonator output device for producing thrust comprises gas-dynamic resonator, which cavity is interconnected with air supply channel through annular nozzle, combustible mixture forming chamber, fuel feed elements connected to it, and outlet communicated with cavity of gas-dynamic resonator. Annular nozzle is made as two-channel, has an internal wall common for both channels, which moves relative to the axis of the two-channel annular nozzle, which separates the air supply channel and forms along with the edge of the gas-dynamic resonator the channel for supply of combustible mixture, which is connected to the output of the chamber for formation of combustible mixture. Outlets of both channels of annular nozzle are made tangential, and its diameter is equal to diameter of cut of gas-dynamic resonator. Cavity of the gas-dynamic resonator is made in the form of a spherical segment. Chamber of combustible mixture formation input is equipped with controlled high-temperature gas source.

EFFECT: invention is aimed at expansion of stable operation range of controlled intermittent gas-dynamic detonation resonator output device for thrust generation due to increased variability of possible control laws.
