The purpose of the contract was twofold 1 to attempt laboratory verification of the analytically predicted effects of environmentally-stressed windows on photographic image quality, and 2 to perform an engineering investigation directed toward the more precise determination of the window environment to be expected in a hypersonic vehicle, and the feasibility of reducing the severity of such an environment. Both objectives were fulfilled. It is recommended that flight tests be considered in any subsequent program, in order to more closely simulate the environmental factors which affect window performance. It is further recommended that research be directed toward the attainment of a suitable method for direct measurement of temperature distributions within glass panels.
