  • Low mass flow reaction jet
    Patent number: 6752351
    Abstract: A control system for a flying vehicle in an atmospheric environment, the vehicle having an aerodynamic shape including a front end and a rear end including a plurality of attitude control jet nozzles spaced outward from the vehicle near the rear end of the vehicle or a trailing edge of a vehicle part; and a generator for providing a low mass flow of a fluid through the attitude control jet nozzles to create an area of high pressure immediately forward of the nozzles and adjacent the flying vehicle, wherein the location of the attitude control jet nozzles is so close to the rear end of the vehicle that any area of low pressure created by the low mass flow of fluid through the attitude control jet nozzles does not contact the vehicle.
