Abstract : Several different types of insulating heat shields were subjected to aerodynamic tests and radiant-heating tests to obtain a better insight into the problems involved when the primary structure of an aerodynamically heated vehicle is substantially cooler than the exposed external surface. One of the main problems was a proper allowance for thermal expansion caused by these large temperature differences, so that undue distortion or thermal stresses would not occur in either the outer shield or the underlying structure. A corrugated outer skin with suitably designed expansion joints was a feature of the specimens tested. (Author)
