  • Multichannel hall effect thruster
    Patent number: 7030576
    Abstract: A Hall effect thruster for propelling spacecraft and satellites includes at least two acceleration channels, each of the channels has a closed end and an open end, and a plurality of flux guides adjacent each of the channels. The plurality of flux guides includes an innermost flux guide, an outermost flux guide, and at least one intermediate flux guide. Each intermediate flux guide helps provide a magnetic field to each of two adjacent acceleration channels.

  • Adaptable solid-hybrid rocket for crew escape and orbital injection propulsion
    Patent number: 6629673
    Abstract: The present invention relates to a propulsion system for transporting a crew transfer vehicle. The propulsion system has a casing which defines a chamber, a solid propellant system positioned within the chamber for generating one of emergency escape propulsion during an emergency portion of an ascent flight and orbital injection propulsion during normal flight operations, and a sustain propulsion system communicating with the chamber for sustaining one of the emergency escape propulsion during the emergency portion of the ascent flight and orbital injection propulsion during the normal flight operations. In one embodiment of the present invention, the sustain propulsion system comprises a hybrid solid fuel grain and liquid oxidizer system. In a second embodiment of the present invention, the secondary propulsion system comprises a liquid fuel and liquid oxidizer system.
