Abstract: A summary of dome protecting technologies design of high-velocity guided missiles was made in this paper. Based on a lot of US patents and other references, the classification of dome protecting design methods and analysis of the strengths and weaknesses and the scope of application of the various technologies was made. The temperature and thermal stress of the dome surface increased as the rise of the missile flight. Mach 2.5 is usually considered to be the thermal barrier boundary in aviation world. Conventional methods and materials can be used to design and manufacture aircraft when temperature is below this boundary, otherwise some measures must be taken to overcome the problem of aerodynamic heating, such as removal of a dome cover, installation of the shock wave cone, dome outline design and dome cooling technology.
