DEEP CONTROL ENGINE CONTROL METHOD Russian patent published in 2020 - IPC F02K9/26 

FIELD: astronautics.

SUBSTANCE: invention relates to rocket engineering, particularly, to control of solid-propellant rocket engines. In the disclosed method of controlling a deep-motion engine, comprising changing the area of the nozzle critical section by feeding a control signal of the engine control system to the nozzle drive, which is generated depending on the measured pressure in the engine, according to the invention, stability of dependence of the combustion speed on the pressure in the engine combustion chamber is provided by changing the fuel combustion speed signal by means of the dynamic advance link introduced into the engine fuel combustion rate calculating circuit, as a result of which the pressure signal in the combustion chamber of the model engine is changed and supplied to the input of the control system, which is readjusted to the corresponding to this signal, then this control system is installed on the engine and thus its control signal is corrected.

EFFECT: technical result is providing stability of dependence of combustion rate on pressure in combustion chamber and preventing attenuation of fuel charge in low-thrust modes.
