  • Patent number: 6729580
    Abstract: A system for directing an object is disclosed. The system includes a first gyroscope with a first rotating rotor and a second gyroscope with a second rotating rotor. Each gyroscope has a motor that rotates a first gimbal coupled to the rotor and a brake that decreases the rotation of a second gimbal coupled to the first gimbal. The first gyroscope and the second gyroscope generate a torque.
    Type: Grant

  • Patent number: 5860620
    Abstract: A ram wing vehicle comprises a main structure extending between a nose end and a tail end, including an aerodynamic lifting body having an aspect ratio less than approximately 1.0 and extending between a leading edge and a trailing edge. The ratio of the thickness of the lifting body intermediate the leading edge and the trailing edge to the length of the chord thereof is greater than approximately 1:8. A propulsion source is provided adjacent the nose end for generating an efflux and for directing the efflux beyond the tail end in a direction away from the nose end. A directional control mechanism is positioned adjacent the nose end for turning the vehicle about the yaw axis into a curve having a center and so vectoring the efflux from the propulsion source as to direct the efflux to the outside of the turn and the nose end toward the center of the curve.
