The LR64 Liquid Propellant Rocket Engine, consists of a propulsion unit, a cartridge actuated multipurpose nitrogen valve, a c
16、artridge actuated oxidizer valve and shear fitting, a cartridge actuated fuel valve and shear fitting, and two nitrogen check valves, 3.1.1 Propulsion Unit. The propulsion unit consists of a booster thrust chamber, a sustainer thrust chamber, a propellant flow selector valve, a cartridge actuated bo
17、oster shut-off valve, a thrust mount, and miscellaneous fittings and tubing. 3.1.2 Associated Equipment. Associated with the LE64 Rocket Engine (but not a part of it) are a fuel tank, an oxidizer tank, a nitrogen tank, ia.pulse cartridges, burst diaphragms and holders, engine section structure, air
18、launch structure, lines, and fittings. 3.1.3 Operation. The LR64 Rocket Engine is prepared for flight by installation of impulse cartridges in the nitrogen, oxidizer, fuel and booster shut-off valves. the desired engine thrust level is selected on the propellant flow selector valve. The engine start
19、 sequence is initiated shortly after launch by action of the targets programmer. The nitrogen valve is opened and the stored gas flows through the nitrogen pressure regulator to pres- surize the propellant tanks. Upon actuation of the shear fittings in the prcFcllant valves, the pressurized propella
20、nts flow from the propellant tanks through the propellant flow selector valve into the thrust chambers. The hypergolic propellants ignite on contact. thrust chamber is shut off by energizing the impulse cartridge in the booster shut-off valve as a function of missile target velocity, The nitrogen ta
