METHOD FOR FORMING CONTINUOUS DETONATION WITHOUT DEFLAGRATION IN A COMBUSTION CHAMBER Russian patent published in 2018 - IPC F02K7/06 

FIELD: various technological processes.

SUBSTANCE: invention relates to chemical fuel power plants. Method for forming continuous detonation in an engine combustion chamber comprises forming an engine combustion chamber comprising a non-simply-connected volume Ω, in which there is a closed curve ω, passing through the points furthest from the opposite walls of the engine. Engine combustion chamber is hydrodynamically connected to the sources of the combustible mixture components, combustible mixture is formed in the engine combustion chamber, detonation wave Ω whose front moves continuously along a closed contour ω is organized in the volume, and evacuation of products from the engine combustion chamber is organized. Volume Ω is formed as a closed channel. Mechanical valves hydrodynamically associated with the volume of the engine combustion chamber and the sources of the combustible mixture components are formed. Each of the mechanical valves is closed when detonation wave approaches its vicinity and is opened after evacuation of combustion products from its vicinity. Combustion products from the volume of the closed channel Ω are evacuated through openings in its walls and it is ensured that there is no deflagration of the combustible mixture to be formed in the entire volume of the combustion chamber by reducing the temperature of the medium to a temperature below the ignition temperature of fuel mixture T* in each combustion chamber element in which the combustible mixture is formed, before its formation in the element.

EFFECT: invention provides more complete use of detonation combustion and increased efficiency.
