<p>An unmanned air vehicle (UAV) (100) having a ducted fan configuration with a propeller (114) mounted inside of an opening (104) that extends longitudinally through the fuselage (102) is shown. The UAV also includes a gyroscopic stabilization device (240) which is attached to the propeller shaft (112) such that rotation of the propeller shaft (112) also results in rotation of the gyroscopic stabilization device (240). The gyroscopic stabilization device (240) has sufficient mass and rotates at a sufficient angular velocity to gyroscopically stabilize the aircraft (100) during flight. In one embodiment, the gyroscopic stabilization device (240) comprises a ring mounted to the outer tips of the propeller (114) and in another embodiment comprises a disc.</p> |
