  • Ground hydraulic system hypergolic slug injection
    Patent number: 10975805
    Abstract: An engine start system includes a facility that has a ground based hydraulic pressurization system and a combustor of a liquid propellant rocket engine. The engine is fluidly coupled to the ground based hydraulic pressurization system. The liquid propellant rocket engine is operably detachable from the ground based hydraulic pressurization system.
    Type: Grant
    Filed: July 11, 2017
    Date of Patent: April 13, 2021
    Assignee: AEROJET ROCKETDYNE, INC.
    Inventors: Douglas Parker, Frederick Dodd

  • Low velocity injector manifold for hypergolic rocket engine
    Patent number: 9404441
    Abstract: A fuel manifold for a thrust chamber assembly includes a main fuel chamber which is generally frustro-conical in shape. The main fuel chamber provides a resonance frequency that is different than an acoustic resonance frequency of a combustion chamber.
