摘要
为解决飞行器高速飞行条件下天线罩在电结构设计中所面临的力、热、电三方面的矛盾,本文应用阻抗匹配技术,通过在隔热层与承载层之间引入介电常数渐变匹配层,使天线罩在满足力、热性能的基础上,其电性能得到了显著提升。该技术的应用为天线罩传统电结构设计领域增添了一条可行的技术途径,可有效的解决耐高温等高性能天线罩的设计瓶颈问题。
In the hypersonic flight conditions,the radome will have to face the contradiction between the mechanical,thermal and electrionics in electrical structure design. In order to solve this contradiction,this paper apply the impedance matching techniques,introduce the permittivity matching layer between the mechanical layer and the heat insulation layer. Using this techinque,the electrical property have been significantly improved based on satisfying the mechanical property and the thermal property. The application of this techniques can provide a feasible technical way for traditional area of electrical structure design,and can effectively solve the bottleneck problem of designing high temperature radome and other high performance radome.
