  • Hybrid rocket system and integrated motor for use therein
    Patent number: 6092366
    Abstract: A hybrid rocket system and motor includes an oxidant tank communicating with a combustion chamber containing a solid fuel grain. The passage from the oxidant tank to the combustion chamber is obstructed by a fill tube which fills the oxidant tank with oxidant and pressurizes it. Once the tank is full, the fill tube is displaced from the tank-chamber passage to deliver oxidant to the grain and initiate the combustion process. The motor may be an integral part of the rocket, or it may be a modular, expendable or exchangeable cartridge-type device inserted into a reusable body.
    Type: Grant
    Filed: April 9, 1999
    Date of Patent: July 25, 2000
    Assignee: Hy-Pat Corporation
    Inventors: Kevin W. Smith, Korey R. Kline, Theodore C. Slack, Jr., Andrew E. Mossberg
