Title:
2つの連結された部材間の相対回転を制御するための装置およびこのような装置を少なくとも1つ用いた、特に宇宙船のための展張可能な機械構造体
Document Type and Number:
Japanese Patent JP4334767
Kind Code:
B2
Abstract:
To control a relative rotation between two elements (10, 12), such as flaps of a deployable mechanical structure, on a space vehicle, a torsion bar (16) is used made of a bistable shape memory alloy, heated over its whole length by heaters stuck on the bar and retained by hooping rings. A stop (22) restricts pivoting to the pre-set pivoting angle to be controlled. Excess pivoting of the torsion bar (16) is applied to a mechanical fuse (18), interposed between the bar and one (12) of the elements.
