目前天线窗的研制工作正在日益受到重视。天线窗可以为导弹和再入飞行器提供通讯渠道,它对于试验飞行器的诊断、与工作系统的通讯以及获取飞行器完成预定任务所需的信息来说都是必不可少的。但是,天线窗的烧蚀和热响应数据却很少能从已回收的飞行器上得到,而飞行试验的遥测结果往往又不是十分肯定的,因此,天线窗系统的设计就需要依靠地面烧蚀试验的结果。较有成效的试验方法是用电弧加热的气体作为试验介质的亚音速管道流试验方法。本文描述了利用亚音速管道流进行的天线窗试验,说明了试验系统的适应性,所能提供的环境变量以及用来获得性能数据和校准结果的测试仪表。试验包括材料性能评定及鉴定试验,分系统部件设计试验和相互干扰研究。文中还列举了一些试验结果。
At present, the research and manufacture of antenna windows are getting more and more attention. Antenna windows provide a means of communication for missiles and reentry vehicles and are essential for the diagnosis of experimental aircraft, their communication with the work system, and the information needed to obtain the aircraft’s intended mission. However, the ablation and thermal response data of the antenna window are seldom obtained from the recovered aircraft, and the telemetry results of the flight test are often not quite sure. Therefore, the design of the antenna window system needs to rely on the ground ablation test the result of. More effective test method is the use of arc-heated gas as the test medium subsonic pipe flow test method. This article describes an antenna window test using subsonic pipe flow illustrating the suitability of the test system, the available environmental variables, and the test instrumentation used to obtain performance data and calibration results. Tests include material performance evaluation and qualification tests, subsystems and component design tests and mutual interference studies. The article also lists some experimental results.
