METHOD OF FILLING LIQUID OXYGEN OF CARRIER ROCKET TANK OF MISSILE SYSTEM

摘要

A method of filling liquid oxygen of a carrier rocket tank of a missile system is based on supply of liquid oxygen into a bottom of a horizontal tank and withdrawal of its steam when connecting the tank top with a ground cryogenic tank, with separation therein of gas-liquid volume from the main volume of tank. It includes filling the tank with liquid oxygen and providing a predetermined temperature of liquid oxygen in the tank during aircraft flight up to delivery of the carrier rocket at the predetermined height by supplying helium for bubbling through the liquid oxygen. Supercooled liquid oxygen is supplied into the tank with its pouring from the tank into the ground cryogenic tank after filling the tank, while maintaining in the ground cryogenic tank the excess pressure, which corresponds to the nominal pressure in the tank. Supply of supercooled liquid oxygen into the tank is carried out up to obtaining the oxygen temperature value at the outlet of the tank below the predetermined temperature of liquid oxygen in the tank prior to delivery of the carrier rocket for the value of oxygen heating in the tank up to the moment of delivery of the carrier rocket followed by fueling stop. During flight of an aircraft before delivery of the carrier rocket helium for bubbling is fed into the gas-liquid volume of the tank from a source of compressed helium located on the aircraft.
