Abstract : Eight samples of foam-glass fiber type insulation panels have been exposed to a Mach 6.5, 4300R gas stream to determine the effects of high temperature, high velocity gases on the panels. The inner surface of the panels was cooled to simulate the liquid hydrogen tank wall conditions. The samples were composed of 0.5-inch thick foam type insulation enclosed between two 0.01-inch thick glass fiber laminates. Six samples were reinforced with a sine pattern core. A coating of a flat black paint was provided over the heated surface of the two samples without sine core reinforcement. Charring of the surface was experienced by the sine core panel when exposed to the high temperature stream for over 25 seconds. The black paint coating experienced blistering in an 8-second exposure.
