METHOD FOR FORMING CONTINUOUS DETONATION WITHOUT DEFLAGRATION IN A COMBUSTION CHAMBER

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.8 cl, 5 dwg Изобретение относится к энергоустановкам на химическом топливе. Способ формирования непрерывной детонации в камере сгорания двигателя заключается в формировании камеры сгорания двигателя, содержащей неодносвязный объем Ω, в котором имеется замкнутая кривая ω, проходящая через точки, наиболее удаленные от противоположных стенок камеры сгорания двигателя. Гидродинамически соединяют камеру сгорания двигателя с источниками компонент горючей смеси, формируют в камере сгорания двигателя горючую смесь, организуют в объеме Ω детонационную волну, фронт которой перемещается непрерывно по замкнутому контуру ω, и организуют эвакуацию продуктов из камеры сгорания двигателя. Объем Ω формируют в виде замкнутого канала. Формируют механические клапаны, гидродинамически связанные с объемом камеры сгорания двигателя и источниками компонент горючей смес
