Stéphan Joseph ZURBACH has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Engine for a spacecraft, and spacecraft comprising such an engine
    Patent number: 10023328
    Abstract: A space vehicle engine (10) comprising a chemical thruster having a nozzle (30) for ejecting combustion gas, together with a Hall effect thruster. The engine is arranged in such a manner that the nozzle serves as the ejection channel for particles ejected by the Hall effect thruster when it is in operation. The engine can deliver high thrust with low specific impulse or relatively low thrust with large specific impulse.
    Type: Grant
    Filed: May 13, 2015
    Date of Patent: July 17, 2018
    Assignee: SAFRAN AIRCRAFT ENGINES
    Inventors: Stéphan Joseph Zurbach, Frédéric Raphaël Jean Marchandise
