A comparison is made between the time history of skin temperature measured on the nose of a V-2 missile and the time history of the temperature computed by the use of Eber's experimental relation for heat-transfer coefficients for conical bodies under supersonic conditions. The agreement obtained is felt to justify the use of Eber's relation in the calculation of skin temperatures under flight conditions. A general method developed for making such skin-temperature calculations is used to compute the variation of skin temperature with time for a wide range of values of the pertinent parameters. The results show that by proper selection of the basic parameters the increase of skin temperature during a limited time of flight can be held to structurally permissible values. Methods are given for taking into account when necessary, the effects of solar heating and the radiation exchanged between the skin and atmosphere. Time histories of skin temperature are compute& for hypothetical supersonic flight plans.
