Description / Abstract:
This 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 design parameters are intended to optimize component
loading characteristics and maximize wire shear capabilities for
both high and pressure applications.
Application
The equations presented herein were developed for use with parts
requiring a swiveling action in relation to each other and still
retain an axial load capability. The most prevalent application
would be the attachment of coupling nuts on hydraulic tube fittings
and hose assemblies.
Thrust wire lengths and insertion depths used with the designs
herein should be determined using ARP4988.
