Abstract:

The aerodynamic heating accompanying supersonic and hypersonic flight renders design for infinite lifetime impossible. At moderately high temperatures creep sets in and causes rupture in tension and buckling in compression even under relatively small loads if they act for a sufficiently long time. At extremely high temperatures the structural material, or its protective covering, melts, vaporizes, sublimes or burns. A few simple methods of analysis are presented with the aid of which approximate calculations of the lifetime can be carried out. Author
