METHOD OF DETONATION FUEL COMBUSTION TO PRODUCE MOTIVE FORCE AND DETONATION ENGINE Russian patent published in 2025 - IPC F02K7/04 F23R7/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering and engine building, namely to detonation air-jet engines. Method of detonation fuel combustion to produce motive force, characterized by supply of fuel mixture into annular detonation chamber, formed between the outer and inner housings, repeating each other in shape and facing each other, in which continuous detonation is initiated, continuing as the said mixture components enter the chamber, and in order to maintain detonation in the detonation chamber annular channel behind the detonation wave in the gas ionization region with the fuel mixture combustion maximum high temperature between annular electrodes mounted in the detonation chamber on the outer and inner housings facing each other surfaces, discharges are formed with the possibility of following the rear edge of the detonation wave, which heat the unburned residues of the fuel mixture and gases formed during the combustion of the fuel mixture, which leads to an increase in pressure in the tail of the detonation wave, wherein the discharge power controls the detonation wave passage speed in the annular detonation chamber and stabilizes its occurrence, wherein detonation control is performed by changing volume of detonation chamber by moving inner housing inside outer housing, and part of the kinetic energy of the detonation wave is transferred to air flows passing through the central ejection channel formed inside the inner housing.

EFFECT: providing afterburning of a fuel-air mixture and gases formed during its combustion and improving the functionality of an engine.
