In-flight thermic problems encountered with a ballistic missile: General study

A calculation method that gives the temperature distribution within a body placed in a flow and following a trajectory, corresponding to the flight conditions of a missile, is defined. The method is to be incorporated in a minicomputer program. Heat transmission across the flow boundary layer, and then by conduction through a body composed of a succession of mediums whose thermic characteristics differ, was studied, supposing that the heat flow is monodimensional. Results are used to elaborate calculation schemes, and a program is established. An application of the program is recounted.
