ABSTRACT:
A flexible wire is secured at one end to the umbilical plug and at the ot to a sheave of a rotary actuator. The actuator is driven by launch-gas pressure to reel in the wire and retract the plug. A plug stop is mounted on the launch tube in the path of travel of the plug. Lift-off of the missile carries the plug into the stop to disengage and free it for retraction. The flexible wire coupling is provided with a slack portion to accommodate shock excursions and assure disengagement of the plug prior to retraction.
