摘要

声爆问题是目前制约超声速民机研制的核心关键问题。但是，目前国内外关于声爆的飞行试验测试数据非常匮乏，严重制约了声爆预测与低声爆技术发展。基于零壹空间公司的"重庆两江之星"号OS-X0科学试验飞行器，航空工业气动院进行了声爆的飞行试验研究。采用航空工业气动院研发的飞行过程声爆信号地面测量技术成功获得了OS-X0试验飞行器在真实大气环境下的地面声爆信号，借助ARI_Boom声爆数值模拟平台对数据进行了分析和整理。数值计算结果与真实试验测量结果总体符合较好，但仍存在一定差异，这表明真实飞行环境下影响声爆特征的因素较多，在超声速飞行器声爆理论和预测方法等方面还需更深入的研究，同时飞行试验测量技术也有待进一步提高。

Abstract

Sonic boom is one of the key issues for research and development of supersonic civil airlines. In the past years

plenty of numerical simulations and wind tunnel tests have been performed

which make the researchers have a certain understanding of its mechanism. However

the flight measurement data are in scarcity both at home and abroad

which seriously restricts the development of sonic boom prediction and reduction techniques. Based on the scientific flight experiment aircraft of "Star of Chongqing Liangjiang" with No. OS-X0

the flight measurement of sonic boom was performed by AVIC Aerodynamics Research Institute (AVIC ARI). The sonic boom signature on the ground after a long distance propagation in the real atmosphere environment is captured by the flight measurement system developed by AVIC ARI

and the measured data has been analyzed by the ARI_Boom in-house code. The numerical results are in reasonably agreement with the flight test data

although there exists some discrepancy due to the fact that many factors in the real atmosphere environment have influences on the sonic boom level. To improve the agreement

the sonic boom theory and prediction methods as well as the flight measurement system need to be improved.
