<p>A pay out system for paying out a flexible elongated element such as a filament, connecting a first object such as an air vehicle (2), to a second object such as a launcher (4), includes a bobbin (8) carried by the first object and having a first flexible elongated element (6) wound therearound one end of which is connected to the first object and the opposite end of which is connected to the second object by a second flexible elongated element (6) wound in loop form on a second bobbin (10) adjacent to the second object. A tension sensor senses the tension in the second flexible elongated element. A clutch normally couples the second bobbin to the tension sensor but is effective, when the tension in the second flexible elongated element reaches a predetermined value, to decouple the second bobbin and to permit it to rotate in a direction to pay out the second flexible elongated element from the second bobbin. <IMAGE></p> |
