The invention is in the field of engine building technology and may be used in space technology or aviation. Liquid-propellant rockets with Laval nozzles are well known, and they have the following insufficiencies: (1) high fuel consumption rates, which lead to increased dimensions and engine weight and boosters; (2) a relatively low combustion efficiency, because the low mass of the combustion products are emitted into the environment; (3) the large length of the de Laval nozzles with increased expansion ratios increase the dimensions and the engine weight; (4) use of high temperature rocket propellants—combustion products—in the camera and de Laval nozzle.
