  • Injection head for a liquid-propelled rocket engine
    Patent number: 7293402
    Abstract: An injection head for a liquid-propelled rocket engine has a plurality of first and second injection bores for injecting jets of first and second propellant constituents, respectively, into the combustion chamber of a rocket engine, with mutual mixing of propellant constituents. The first injection bores are provided for injecting jets of the first propellant constituent with a high impulse, and the second injection bores are provided for injecting propellant jets of the second propellant constituent with a low impulse. In addition, the first and second injection bores are mutually arranged such that an admixing of the second propellant constituent to the first propellant constituent takes place under an ejector effect of the propellant jets of the first propellant constituent leaving the first injection bores.
