ABSTRACT	Heating tests of a model of a nose cap fitting were carried out in order to understand the behavior of thermal conduction of the nose cap fitting of hypersonic re-entry vehicles. The model was constructed of materials equivalent to those used for the nose cap fitting of the Hypersonic Flight Experiment (HYFLEX)vehicle, and was of the same size. The model was heated using a xenon lamp heating system. Tests were carried out in a vacuum, and the temperature history at selected locations on the model were measured with thermocouples. It was observed that the temperature of the main structure of the airframe hardly rose,when the temperature of the back surface of the nose cap reached its peak value.
