X-20 WINDOW TESTS

Abstract

This report describes two structural integrity tests of the X-20A high temperature side window. One test simulated the air leakage from the window during boost and the second test simulated the thermal cycle experienced during reentry. The outside window panel failed prematurely during the thermal cycle, apparently the result of excessive thermal gradients through the frame and a stress concentration caused by thermistor instrumentation leads passing through the frame and under the window seals.
