Abstract
A folding fin assembly (2) for a flight vehicle in which a fin (3) is carried for rotation about a chordwise axis (Z--Z) upon a turntable (9), the turntable (9) being itself turnable with reference to a fixed base (5) about a given axis (W--W) transverse to the chordwise axis (Z--Z). This is effected by meshing worm gears (14, 8) which transmit rotary movement to the turntable (9) as the fin (3) is rotated about the chordwise axis. The fin (3) lies flat against the surface of the flight vehicle with its chordwise axis (Z--Z) transverse to a fore-and-aft axis (X--X) of the flight vehicle and on erection is turned so that the chordwise axis (Z--Z) lies parallel to the fore-and-aft axis (X--X) of the flight vehicle.
