  1. Abstract : the effects of airfoil geometric parameters on wing " s spacial and polarized scattering characteristics have been systematically revealed . the results of the study indicated that the calculating value of diffraction from trailing edge by using the formula of the straight wedge is very far from experimental results for vertical polarization , and the contribution of thickness of the trailing edge to scattering must be considered in the calculation . the scattering peak of leading edge depends only on radius of airfoil for horizontal polarization . but for vertical polarization , it depends on maximum thickness and the location of maximum thickness . engineering formulas for evaluating all scattering peaks were given in the paper . it is important for the design of low - rcs wing
    文摘:系統地揭示了翼形幾何參數對機翼的空間散射特性、極化散射特性的影響規律.研究發現,在垂直極化狀態下用理論尖劈公式計算機翼后緣繞射的計算結果與實驗結果相差甚遠.提出在垂直極化狀態下機翼后緣繞射的計算必須將后緣厚度考慮在內的見解.對于水平極化,前緣散射波峰只與前緣半徑有關;而對于垂直極化,前緣散射波峰與翼形最大厚度以及最大厚度位置有關.給出前后緣散射波峰的工程估算公式,為低雷達散射截面( rcs )機翼設計提供依據
