  • Single actuation pushing device driven by a material with form memory
    Patent number: 5829253
    Abstract: To command notably the unclamping and the separation of two components, on a spacecraft, such as a satellite or a probe, a single actuation pushing device (10) is driven by a form memory device (36) positioned in a casing (12), between a wall (18) of the latter and a boss (24). It is linked to a heater (38). A system to prevent mistakes (20, 26, 32), sensitive to a displacement of the component (24) caused by an elongation of the device (36), prevents assembly of the pushing device (10) when it has already been actuated.
