SYSTEM FOR TEMPORARILY BLOCKING THE RELATIVE DISPLACEMENT OF TWO BODIES, FOLLOWING AT LEAST A PRESET DIRECTION |
摘要 |
The blocking system comprises a first interface element adapted to cooperate with a first of two bodies; a second interface element adapted to cooperate with the second of the two bodies; blocking element adapted to cooperate with the interface elements to ensure temporary blocking and comprising a frangible zone; a rupture device consisting of a shape memory alloy adapted to be deformed by elongation through heating to break the frangible zone, by which the second body becomes free to move relative to the first body; and heating element adapted to heat the rupture device beyond the critical temperature to cause the shape memory alloy to be deformed. A redundancy of heating element may be provided, as well as a retraction of at least part of the blocking element in a housing defined by one of the interface elements. The invention is useful for blocking the displacement of a tilting platform with respect to a fixed platform in the field of space applications. |
