Abstract
An aerodynamic device includes a rotor connected, for rotation about an axis, by bearings to a bridle to which a securing line is attached. At least one stabilizer fin is hinged to the rotor on an axis at right angles to the rotation axis. Each stabilizer fin is free to move angularly about its hinge axis in flight.
Claims15
An aerodynamic device, comprising:
- a rotor coupled to retaining means which define an axis of rotation for the rotor;
- a stabiliser fin carried on said rotor;
- means interconnecting said stabiliser fin and rotor for assuring the capability of free hinging movement of said stabiliser fin through a range of angles with respect to said rotor during flight, said interconnecting means including hinge means hingedly connecting said stabiliser fin on the rotor for free angular movement about a hinge axis which lies in a plane normal to the rotation axis, the arrangement being such that in flight the stabiliser fin is free to move angularly about said hinge axis under effect of centrifugal and aerodynamic forces.
An aerodynamic device, comprising:
- a rotor coupled to retaining means which define an axis of rotation for the rotor;
- a stabiliser fin connected to said rotor along a hinge axis;
- means for maintaining the stabiliser fin free to pivot through a range of angles about said hinge axis in response to centrifugal and aerodynamic forces in flight, said range of angles extending in both angular directions from a fin position perpendicular to said rotor, said maintaining means including hinge means hingedly connecting said stabiliser fin on said rotor.
