Abstract: Abstract: In order to solve the problem of the TMS(thermal management system) on hypersonic aircraft, In this paper, The TMS with LNG was designed, through dynamic simulations, analyzed the performance of the TMS. Com-pared the temperature of different heat source at different take-off ambient temperature. The results show that: the heat sink is insufficient and the TMS performance is poor when the aircraft flying at Ma 7 or returns. It provides evi-dence that LNG presence is necessary, if not the aircraft structure and equipment will be overheated for a long time. LNG can make TMS performance improved, the aircraft structure and equipment overheated phenomenon will not occurs when the LNG is used. In order to analyze the compensatory of volume and weight, The LNG consumption data at different temperatures were listed, an empirical formula was calculated by fitting the data, It can provide a reference for TMS design.

Key words: hypersonic aircraft, LNG, TMS, temperature control performance, compensation assessment
