SCOPE The scope of this SAE Aerospace Information Report (AIR) is to define recommended methods of determining the optimal dimensional relationship of components coupled together using thrust wires for applications such as coupling nuts and fittings. These desig
6、n parameters are intended to optimize component loading characteristics and maximize wire shear capabilities for both high and low pressure applications. 1.1 Application The equations presented herein were developed for use with parts requiring a swiveling action in relation to each other and still
