  • Injection head for the combustion chamber of a rocket propulsion unit
    Patent number: 7850096
    Abstract: An injection head for the combustion chamber of a rock propulsion unit has a base area with a plurality of injection elements distributed on it. Propellant constituents can be injected from each outlet of the injection elements into the combustion chamber, generating hot gases by a mixing and combustion of the propellant constituents in the combustion chamber, which hot gas can be accelerated to a high velocity for generating thrust. The base area of the injection head had a contoured shape which prevents or reduces the formation of zones of a reduced pressure, particularly between directly adjacent outlets.
    Type: Grant
    Filed: February 21, 2008
    Date of Patent: December 14, 2010
    Assignee: Astrium GmbH
    Inventors: Frank Grauer, Gerald Hagemann

  • Method for extending a nozzle and extended nozzle for rocket drives
    Patent number: 7287369
    Abstract: A method for extending a nozzle for a rocket engine is described, in which at least one second region of the contour of the nozzle is arranged as an extension of a first region of the contour of the nozzle. This extension of the first region by the second region occurs at an altitude at which the contour of the open jet of the rocket engine substantially corresponds to the contour of the second region. Also described is a corresponding extendible nozzle for a rocket engine.
