The main reason of extended stall margin was that about 75% axial chord of the tip flow field has been improved.
②第一套方案对离心叶轮大叶片75%左右轴向弦长前尖部流场的改善是失速裕度提高的主要原因；
Most part of the supercritical wing with equal chord and high aspect ratio is provided with 2-D flow characteristics approximately except wing tip.
对翼身组合体等弦长大展弦比超临界机翼，除翼梢处流动三维效应强外，机翼其余部分包括接近翼根附近，均具有近似二维流动的特征。
If no tip weight is added, the CG (or centre of gyration) would be located far behind the centre of lift (about 25% chord point).
如果没有提示的重量是说，企业管治(或中心的回转)将设远远落后于该中心的电梯(约25 %的共鸣点)。
