MISSILE WITH DEPLOYABLE CONTROL FINS

摘要

A missile (20) includes a missile body (22) and a structure for controlling the flight path of the missile body. The control structure includes at least one control fin (28) and an actuator shaft (38) that supports the control fin (28) for rotational missile control movement about a control axis (30) perpendicular to the axis (23) of the missile body (22). A deployment shaft (42) extending from the control fin (28) is rotatable in a deployment shaft bore (46) in the actuator shaft (38), and permits the control fin (28) to rotate from a folded position (56) parallel and adjacent to the missile body (22) to a extended position (58) parallel to the control axis (30).
