ABSTRACT:
A passive load limiting strut particularly useful in limiting loads between a spacecraft and an upper stage during booster first stage operation and thereby permit the launching of heavier spacecraft. The strut operates on the principle of snap through buckling of bar linkages. A tension shaft is telescoped into a compression shaft within a housing. A plurality of bar linkages are connected between each of the shafts and the housing, the bars being oriented at an acute angle in the direction of the tension shaft. In tension, the bar linkages connected to the tension shaft progressively buckle, absorbing tension loads. In compression, the bars connected to the compression shaft progressively buckle, absorbing compression loads. A compression spring intermediate the ends of the shafts further aids in load relief. Collars on the shafts prevent the shafts moving beyond preselected locations.
