ABSTRACT:
An airborne body with extendable fins or wing surfaces which are simultaneously extendable by the action of a drive element through the intermediary of a cam plate arrangement. The cam plate arrangement is formed by a cam plate which possesses two identically-shaped cam tracks for two fins, which tracks are mutually offset along the circumference of the cam plate, and whereby each cam track contacts against an actuating edge of one of the fins, and wherein the axis of rotation of the cam plate, about which it is rotatable through the action of the drive element, conincides with the longitudinal axis of the airborne body.
