Abstract : Comparison of chamber wall temperatures obtained from flight data and static tests at altitude shows some differences. The flight data indicate maximum chamber wall temperatures of 800 F as compared with maximum temperatures of 400 F for static tests on the chamber wall at simulated altitude. Comparison of static data for a foil wrapped and a nonwrapped chamber indicates foil wrapping causes an increase in temperature from 400 F to 700 F. Flight temperatures are sufficiently high to cause epoxy resin boiloff, charring of the chamber wall, and resultant loss of chamber structural strength.
