Finally , the optimization work of one concrete model of the advanced tactical fighter is well done by using such integration design system 并以某先进战斗机总体方案为例,进行了气动隐身优化设计,取得了较好的效果。
For advanced tactical fighter , besides excellent aerodynamic performance , stealthy performance is an important factor for aircraft configuration design 先进战斗机除了具有优良的气动特性外,隐身性能也已经成为其外形设计的重要因素。
Recently , with the higher and higher requirement of the survival ability of the advanced tactical fighter , supersonic cruise has been required as one of the important performance 近年来,随着对战斗机作战性能和生存能力要求的不断提高,超音速巡航已作为战斗机的一项基本指标。
Therefore , in this paper the multi - objective optimization design of aerodynamic and stealthy configuration for the fighter is discussed according to the geometrical characteristics of the advanced tactical fighter . the work is performed as follows : 1 according to the different design requirement in subsonic and supersonic state , with the multi - objective optimization method , the aerodynamic configuration optimization method for different design requirements has been obtained 基于以上考虑,本文从研究气动隐身多目标优化问题的角度出发,针对先进战斗机的外形设计特点,完成了以下工作: 1 、针对现代战斗机亚、超音速的不同设计要求,利用多目标优化设计方法建立了可进行满足不同设计要求的气动外形优化设计方法。
