Abstract:

The development of hypersonic cruise missile, hypersonic boost glider andhypersonic aircraft in foreign countries is briefly introduced, The two key technologies forinfrared radiation signatures of hypersonic vehicle are analyzed, namely simulation oexternal continuous-rarefied flow filed and radiation signatures calculation, The problem ofmulti-component non-equilibrium effect in the research process is pointed out, Finally, thetrend of study on infrared radiation signatures of hypersonic vehicles is envisioned.flow;
