METHOD FOR PRELAUNCH PREPARING THE PNEUMOHYDRAULIC SYSTEM OF FUEL FEED INTO THE COMBUSTION CHAMBER OF LIQUID-PROPELLANT ROCKET

摘要

A method for prelaunch preparing consists in that the displacement of fuel from the liquid volume of fuel tank into the supply line is achieved in the process of the supercharging of the gas volume of fuel tank, when boost pressure reaches intermediate value determined by the appropriate relationship. Proposed method makes it possible to decrease the value of hydroblow in the supply line during its filling due to the lower boost pressure.
