英文摘要： With the development of the near space aerocraft, the aerothermology encounters a series of impending complex problems on the aerothermal transimission, so that a sort of technique which could measure the whole flow field with high precision is urgently required to be developed to solve those problems. Phosphor Thermology Technique (PTT) is one revolutionary development in the aerothermal investigation of the near space aerocraft. This work will continue to study the application of the PTT in the wind tunnel, at the same time, to develop the two-color phosphor luminescence material, to construct the two-color phosphor system for heat transfer measurement, to improve the image/data processing programs, and will finally integrate a test platform for the high precision whole surface thermal environment measurement. The model of complex region on the near space aerocraft will be manufactured, the experiment with PTT in the wind tunnel will give out the detailed analysis and the exact prediction method on the thermal environment parameters of the characteristic region on the near space hypersonic long-distance aerocraft will be developed.
