Detail of the socket in the air rudder mounting plate.
The air rudders, in
conjunction with the carbon jet vanes located in the
engine exhaust, were used to control the missile's attitude. During the early
portion of the missile's flight, it was controlled by the jet vanes. When the
missile reached a velocity sufficient for it to become aerodynamically stable,
the air rudders took over the control function.
The air rudders and carbon vanes were driven by the same actuator assembly and
Note that the air rudders are attached only by a shaft near the top of the
rudder; the shaft rides in this socket in the air rudder mounting plate.
