This paper has mainly made a research on the aerodynamic configuration design of " w " tailless aircraft and the design idea has been presented here . according to the configuration design requirement of certain uav , aerodynamic configuration design has been carried out and two configuration projects are given out at last : forward - swept wing tailless configuration and " w " tailless configuration . the longitudinal and lateral aerodynamic characteristics are obtained by using two aided soft : ug to build up geometrical models and mgaero to calculate flow field 本文研究了“ w ”型无尾布局的气动外形设计,阐述了该布局的气动设计思想,根据型无人机的总体设计技术指标,进行了气动外形设计,提出了两种气动布局方案:前掠翼无尾气动布局和“ w ”型无尾气动布局,利用ug建模软件和mgaero气动分析计算软件计算了两种布局的纵、横向气动性能,分析了前掠翼前缘掠角和翼身融合对气动性能的影响,计算结果表明, “ w ”型气动布局的设计思想是正确的,所设计的“ w ”型无尾气动布局方案的气动性能优越,超过了总体设计技术指标。
