Cable System Components - Flight Controls III

The question that might then come to mind is that HOW is the pulling action of a control cable converted into a pushing one. The answer as was supplied above is via a ‘looped system’. However, there are other components within that loop that result in actuation of a device/control surface etc. Each of these components have a particular function such as:

1 . Serving to change the direction of application of force(Pulleys, Bellcranks, quadrants, jackscrew drums),
2. Transferring the motion of the cables into push-pull ( As above, and Rods, tubes, horns)
3. Acting as a support for the cable (Pulleys, Fairleads)
4. Forming a terminal connection between cable and actuator (sockets, clevises, pins, rod-ends),
5. Forming a connector between repaired sections of cables (cable splices, turnbuckles),
6. Serving as point of adjusting cable tension (temperature compensators, turnbuckles)

For a more vivid description of each component and it’s function, you could refer your Airframe and Poweplant Mechanics Handbook.
