摘要
本文报导了1992年7月在美国纳希维尔召开的 AIAA 第17届航空航天地面试验会议的概况。简要地介绍了讨论航空航天地面试验面临的技术挑战,CFD 和地面试验的相互作用,美国气动力学与气动热力学研究的未来等三个大会报告的内容。介绍了在会议报告中叙述的对高超声速气动试验的新要求和自由飞弹道靶、 脉冲风洞、稀薄气体设备、电弧加热器的新进展。最后,对我国高超声速气动试验的发展提出了建议。
The survey of 17th AIAA Aerospace Ground Testing Con-ference to have been held in Nashvill USA,July 1992 is reported in thispaper.The situation of three plenary session that discussed the technicalchallenges facing aerospace ground-based testing,interaction of CFD andground-based testing and future of aerodynamic/aerothermodynamic re-search in USA,is introduced briefly.The future requirements for hypersonic aerodynamic and aerother-modynamictesting and the new progress of ballistic ranges,impulse windtunnels,rarefied flow facilities and arc heaters to have been describedin the papers of this conference are presented.The suggestions for thedevelopment of hypersonic aerodynamic and aerothermodynamic testingin our country are put forward.
