Corona testing of supersonic airplane high temperature wire

摘要

Wiring within the unpressurized compartments of the supersonic airplane is subjected to environmental stresses which are much greater than in subsonic airplanes. For example, during supersonic flight at an altitude of 73,000 feet the wire will be exposed to an air pressure of 29 torr and temperatures approaching 260°C. These extreme environmental conditions can give rise to corona within the electrical/electronic systems.
