- In this paper, a semi-empirical prediction method of maximum lift coefficient at low subsonic speeds for wings/bodies with high aspect ratio is investigated. 本文研究了大展弦比机翼/机身低亚声速最大升力系数的半经验预测方法。
- Cylindrical-Shaped Discis the only moving part. It is especially designed to produce maximum lift at minimum velocities. There are no wing guides to cause "spinning" with resultant rapid wear. 圆柱形阀瓣是唯一一个活动部件。这是一种能够在最小流速下产生最大提升力的基本结构。没有侧翼导轨,因此不会产生“旋转”合力从而加快磨损。
- For instance, the development of the boundary-layer shape parameter can be prescribed on the upper surface to allow for maximum lift or extended runs of laminar flow, depending on the design requirements. 比如开发了边界层的形状参数;可以指定允许的最高表面上取消或延期举办层流、视乎设计要求.
