摘要
本文通过对高、低速风洞外挂物投放实验技术的研究,提出了一些值得注意的问题。如由于风洞高度不同使得实验结果带来差异,安全迎角范围的选取不仅存在一个“上限”,有时还要考虑到“下限”等。同时还介绍了解决外挂物投放异向拍摄同步性的新方法和回转式投放实验技术。
This paper gives some problems deserve attention bystudying of experimental techniques of store-dropping.In the high-speed and Low-speed Wind-tunnel.For instance,the different wind-tun-nel highness results in different experimental result; there is not on-ly a`upper limit′in selecting the range of the safe angle of attack,sometimes we should even consider a`lower limit′etc.At the sametime the prasent paper also introduces the new way how to solve thesynchronism in taking pictures of the stores-dropping with differentdirections and rotary technique of store-dropping test.
