Description

technical field

[0001] The invention relates to a high-temperature pure air test system and a safety control method, in particular to a regenerative high-temperature pure air test system and a safety control method that can be adjusted in a wide range of working conditions. High temperature and high pressure pure air required. Background technique

[0002] Scramjet directly connected test benches mostly adopt pollution heating methods such as combustion heating or arc heating. However, there are many differences between the ground test performance of the gas generator or arc heating method using methane, hydrogen, alcohol, kerosene and other fuels and the performance of the actual pure air flow in the scramjet engine, mainly due to the simulation. The stream contains H 2 O.CO 2 And components such as NOx will produce "pollution effect".

[0003] Based on the defects of the existing scramjet direct-connection test bench, it has become a development trend to use high-tempe...
