ABSTRACT:
A system for releasing parts of a spacecraft construction that are contained by the use of a tensioned cable, made of a material that will degrade or decompose under the influence of heat, and stretched between two supporting elements of the construction. At least one heating element is connected to an electrical power source mounted into a frame that is attached to the spacecraft structure, in a manner such that the heating element and the opposed cable section are pressed towards each other. The tension in the cable is of sufficient degree to displace the ruptured ends of the cable, when broken, out of contact with the heating element.
