Patent ID: 8581160

Claim:
A gyroscopic stabilizer for use with a propelled body where a fluid flow associated with propulsion of the body passes in a predetermined direction relative to the body, comprising: a ring having a predetermined mass and a predetermined axis; a bearing mounting the ring rotationally on the body with the ring disposed for passage of the fluid axially of the ring; a rocket nozzle being a portion of the propelled body terminating at an exit opening for said fluid flow; and at least one vane mounted on the ring and extending radially from the ring into said flow, said at least one vane being configured so that said flow impinging on said at least one vane motivates the ring rotationally about said axis, whereby rotation of the ring about said axis tends to gyroscopically stabilize the body, and wherein said bearing is disposed on said rocket nozzle at said exit opening and mounts the ring at said exit opening for rotation of the ring about said exit opening.
