INJECTOR FOR BIPROPELLANT ROCKET ENGINE

摘要

PURPOSE: An injector of a bipropellant rocket engine is provided to improve the combustion efficiency by consistently supplying propellants to all sprayers. CONSTITUTION: An injector of a bipropellant rocket engine comprises a propellant feed port(10), a branching unit(20), a first propellant feeding unit, and a second propellant feeding unit. First propellants and second propellants are respectively supplied to one-side of the propellant feed port through a first and second flow passage and discharged to the other side. The branching unit comprises a first spraying hole, a second spraying hole, a third flow passage, and a fourth flow passage. The first and second spraying holes are penetrated into the one side and the other side. One end of the third flow passage is connected to the first flow passage and the other end is connected to the first spraying hole. One end of the fourth flow passage is connected to the second flow passage and the other end is connected to the second spraying hole. The second propellant feeding unit comprises a third and fourth spraying holes and a fifth flow passage. The third and fourth spraying holes are penetrated into the one side and the other side correspondently to each other. One end of the fifth flow passage is connected to the second spraying hole and the other end is connected to the third spraying hole. The first propellant feeding unit comprises a fifth spraying hole and a sixth flow passage. The fifth spraying hole is penetrated into the one side and the other side corresponding to the third spraying hole. The sixth flow passage is connected to the fourth spraying hole and the other end of the sixth flow passage is connected to the fifth spraying hole.
