Thermal test technique of complex structure of hypersonic aircraft

To solve the hypersoinc vehicle complex structure thermal test heater design problem, with a section of the blunt body of the hypersonic vehicle as the test sample, related techniques for high temperature testing of complex structure are studied, including testing program determination, detailed design of heater, measurement of temperature, strain and displacement, as well as the method for heat flux control. High temperature testing of blunt body test sample is completed using a self-designed infrared heater. Large test data, such as temperature, strain and displacement are obtained.Through this study, combing the hypersonic vehicle complex structure heater design process, at the same time, large test data are obtained to provide significant support for structure optimization.
