PROPELLANT SUPPLY EQUIPMENT OF LIQUID ROCKET ENGINE WHICH MOTOR AND PUMP EXIST ON CONNECTION SPACE

摘要

The present invention relates to a propellant supply device for a liquid rocket engine in which a motor and a pump exist in a communication space, and the propellant supply device of the liquid rocket according to the present invention includes a housing including an inflow passage through which the propellant is introduced, and an inner space of the housing. An impeller disposed in, a motor that rotates the impeller, a motor housing that is in communication with the housing, and includes a motor housing for accommodating the motor, and a main flow path that is a passage for discharging the propellant to the combustion chamber of the liquid rocket engine, the The propellant is introduced into the inner space of the motor housing from the inner space of the housing through a region in which the housing and the motor housing are communicated for cooling the motor, and the propellant introduced into the inner space of the motor housing, After flowing inside the motor housing, it may be introduced into the main passage through a first passage member formed inside the motor housing, or may be re-introduced into the housing through a second passage member formed inside the motor housing. .
