摘要
本文简述了超声速飞行器声爆的概念、特征和重要性,重点阐述了以近/远场混合方法为代表的声爆预测思路,综述了声爆数值模拟、风洞试验和飞行测量的发展现状和技术难点;最后给出了探索声爆许可标准、军民合作积累声爆数据、发展精细化的空基测量技术和数学力学相结合的高精度预测模型4个方面的发展建议。
The basic conception,major characteristics and significances of sonic boom for supersonic aircrafts are introduced firstly.Then,the near/far-fields hybrid prediction method containing the CFD,wind tunnel test and flight test is described;Finally,this paper gives the four development proposals including exploring the permission standard of sonic boom,accumulating sonic boom data by military and civilian integration,developing refined airborne measurement approach,and establishing highly accurate mathematically mechanical model.
