ABSTRACT:
The following specification discloses an aerodynamically driven toy that can be in the form of a toy or other animal having a moving appendage such as a tail or wing. The wing, tail or other appendage is driven aerodynamically when passing through a relative wind by virtue of the fact that a turning moment is applied respectively for both negative and positive angles of attack after the appendage, such as the wing of a bird, has been moved through the reverse of the foregoing movement. The angle of attack is changed by virtue of an operating arm that is linked to the wing or appendage so that it moves in a manner whereby the wing will be positively driven upwardly and downwardly at the respective low points and high points of the travel of the wing. This is done by means of turning the wings in a direction to apply a certain angle of attack so that the relative wind will pick up the wing when it is in its lower position and depress it when it is in its upper position. The foregoing aerodynamically driven toy can be attached to a moving vehicle by means of a connector that can either wrap around a portion of a vehicle or be inserted in any other suitable manner to the vehicle's frame or structure. The effect is to create a flapping movement of a wing or other appendage of an animal.
