METHOD FOR REGULATING PARAMETERS OF LIQUID PROPELLANT ENGINE Russian patent published in 2021 - IPC F02K9/56 F02K9/96 

FIELD: regulating.

SUBSTANCE: invention relates to regulating parameters of an object using regulating apparatuses included therein, particularly in rocket and space technology for regulating a liquid propellant engine. The method for regulating parameters of a liquid propellant engine consists in setting the drives of the control aggregates in positions corresponding with the required values of thrust, fuel component ratio, temperatures and pressures of the fuel components at the engine inlet, and are determined by the mathematical model of the engine or by the regulating polynomials of the engine obtained by approximating of the results of calculations performed by the mathematical model of the engine, and are put into the electronic computing machine of the bench control system or the on-board electronic computing machine of the launcher rocket. The mathematical model of the engine is formed by identification according to the results of measuring the parameters of the liquid propellant engine obtained in a preliminary multi-mode bench test. The regulating polynomials of the engine are determined by approximating the results of calculations performed by the mathematical model of the engine.

EFFECT: invention ensures improved accuracy of regulating parameters of a liquid propellant engine.
