  • Flat trajectory projectile
    Patent number: 4389028
    Abstract: An unguided projectile achieves a flat trajectory by generating gravity-ctering aerodynamic lift. The lifting device is stabilized in roll by a displacement-type gyroscope which is mounted directly to the lifting section of the projectile. Both the lifting device and the gyroscope are mounted on bearings to permit free rotation of the projectile body relative to the roll-stabilized lifting section. Lift vector orientation is maintained irrespective of projectile roll.
    Type: Grant
    Filed: January 14, 1976
    Date of Patent: June 21, 1983
    Assignee: The United States of America as represented by the Secretary of the Navy
    Inventors: Chris A. Kalivretenos, Michael A. Brown
  • Adapter assembly for flat trajectory flight
    Patent number: 4374577
    Abstract: An aerodynamic lift-generating adapter assembly secures to the nose of an guided projectile to provide a capability for flat-trajectory flight. The adapter assembly comprises a rotatably-supported, roll-stabilized lift-generating section coupled to an actuator section containing inertia means to initiate gyroscope rotor spinning. The control gyroscope is directly linked to the lift-generating device to maintain fixed orientation of the lift.
