风洞投放试验技术的研究现状与应用综述

多体分离是航空、航天和武器系统总体部门一直极为关注的关键问题，多体间的流场干扰效应产生的气动力和力矩对悬挂物分离相容性有重要影响，基于运动动力学相似的风洞投放试验技术是预测和评估多体分离是否相容的一种非定常试验方法。根据飞行器多体分离相容性的研究需求，结合作者在风洞投放试验技术的研究成果和经验，对风洞投放试验技术的国内外研究现状进行综述。首先回顾了风洞投放试验技术的发展历史，然后对低速和高速风洞投放试验的相似准则及缩比关系进行详细地论述与分析，进而对风洞投放试验的几个关键技术进行综述，最后对风洞投放试验技术存在的问题提出思考与展望。

Research status and application of wind tunnel drop test technology: Review

The compatibility of multi-body separation is a key issue that has always been paid close attention to by the general departments of aviation, aerospace and weapon systems. The aerodynamic force and moment generated by flowfield interference of multi-bodies have an important impact on the compatibility of store separation. The wind tunnel drop test technology based on dynamic similarity is an unsteady test method for the prediction and evaluation of multi-body separation compatibility. Based on the research findings and the author's experience in the study of the wind tunnel drop test technology, this paper summarizes the research status of this technology at home and abroad. The development history of the technology is reviewed, followed by discussions and analyses of the similarity-criteria and scaling-relationship of the wind tunnel drop test. Several key technologies of the wind tunnel test are then summarized, and some thoughts and prospects on the technology are finally presented.
