Controlled rupture mechanism and equipment for structure operating in traction such as controlled release of small satellite involve two stressing members, anvil and punch, and pyrotechnic control

摘要

System includes structure to be broken (10) and rupture mechanism. Rupture mechanism has two stressing members, anvil (20) and punch (30), placed on either side of fibres (10) and pyrotechnic control (40) for causing relative movement of stressing members. Those will impose bending radius of fibres, inferior to bending radius causing them to be ruptured by bending. An Independent claim is also included for the description of the equipment using rupture system.
