【摘要】 翼身融合布局无人机具有较好的升阻特性和隐身特性,拥有广泛的应用前景。为了提高无人机的续航能力,兼顾翼身融合无人机的气动特性和结构重量要求,选择无人机升阻比与全机面积作为优化目标,应用多目标优化方法研究翼身融合无人机的外形设计,提出一种针对翼身融合无人机的外形参数化优化设计方法,并进行实例验证。结果表明:外形优化可以提高无人机升阻比、减轻结构重量,从而获得合理的翼身融合无人机设计方案。

【Abstract】 Blended wing body(BWB)unmanned aerial vehicle(UAV)has good lift to drag ratio and stealth characteristics,and is of broad application prospects.In order to improve the endurance of the UAV,considering aerodynamic characteristic and structure weight requirement of blended wing body UAV,lift to drag radio and aircraft area are taken as optimization objectives,using multi-objective optimization method to study configuration design of blended wing body UAV.A parametrized configuration optimization design method of UAV is provided,and a practical example is given.The analysis results indicate that configuration optimization can increase lift to drag radio of UAV,reduce structure weight,and get an excellent design scheme of blended wing body UAV.
