对于大部分的运输类飞机来说,诱导阻力占到总阻力40%左右。各大航空企业都在致力于研究翼梢小翼,以减少诱导阻力,提高飞机性能。当前,空客A320NEO和波音737MAX均将采用新型的翼梢小翼。本文提出了一种全新布局的阶梯式小翼,基于翼身组合体高速构型,使用数值求解NS方程的方法,对阶梯式翼梢小翼在机翼翼尖处的安装位置、展向起始位置、根弦大小和梢根比进行参数化研究。
For most transport aircraft, induced resistance accounted for about 40% of the total resistance. Major aviation companies are committed to the research wingtip to reduce induced resistance and improve aircraft performance. Currently, the new Airbus A320NEO and Boeing 737MAX will use the new winglet. This paper presents a new layout of the wartier winglets. Based on the high-speed configuration of the wing-body assembly, the numerical solution of the NS equation is used to estimate the installation position of the winglets at the wingtips. Position, root string size and shoot root ratio parameterization study.
