FIELD: engines and pumps.;SUBSTANCE: invention relates to the field of rocket engine technology, oriented at space transport systems. The method of liquid propellant rocket engine boosting by thrust based on variation of energy parameters of functioning, according to the invention, boosting is done by supplying some gas from a gas tract of at least one of fuel components, or generator gas, or their mixture, at least to one additional turbine, interacting at least with one of the main turbopump sets (TPS), and after leaving it the gas is sent for further use or discharge. After discharge from the additional turbine the gas is sent to the inlet of the discharge nozzle or into the nozzle of the chamber, or to the inlet of the additional turbine, or into a heat exchanger. A liquid propellant rocket engine (LPRE), comprising a chamber, control and regulation units, the TPS with the main and at least one additional turbine, besides, the gas tract of the main turbine is connected to the inlet to the chamber, in which according to the invention the gas tract of at least one of the components or their combustion products is equipped with an additional manifold, connecting it with the inlet of at least one additional turbine and outlet from it, at the same time the manifold is equipped with a local control system installed upstream or downstream the main turbine, and the outlet of the manifold is connected with the system of gas removal and/or the system of its reuse.;EFFECT: invention provides for higher cost-effectiveness of an LPRE at rated mode of operation and further increase (by more than 1,3 times) of thrust during engine boosting.;4 cl, 2 dwg
