A cable installation simulator from W. L. Gore & Associates aids in evaluating the stress of installation on microwave airframe assemblies, thereby minimizing the risk of cable assembly damage or failure during installation. By comparing signal integrity before and after installation, Gore can engineer assemblies that withstand airframe installation as well as the demands of the aircraft’s flight envelope. Use of the installation simulator gives aircraft manufacturers and installers evidence that their assemblies will provide the same level of electrical performance after installation as when they are new. In addition, they can be assured that the assemblies will continue to perform reliably throughout the service life of the aircraft.
