順槳槳葉 的英文怎麼說
中文拼音 [shùnjiǎngjiǎngyè]
順槳槳葉
英文
feathered blade-
The paper has improved the existing lifting - line and lifting - surface design method by including the rake and skew and solving the optimum circulation distribution with the optimum theory. the blade geometry is expressed with b - spline for the lift - surface method. the boundary condition on the blade is transformed to minimize the summation of the square of normal velocities, the fair blade geometry can be obtained by present technique and the design quality is better
改進了現有的升力線和升力面設計方法，在升力線設計中計及槳葉的縱傾和側斜的影響，用優化理論求解最佳環量分佈，升力面設計中用b樣條來擬合槳葉，將物面邊界條件轉化為求法向速度分量的平方最小，由此可得到光順的槳葉幾何形狀，提高和改進了設計質量。The primary purpose of this paper is how to solve the overloaded propeller ' s condition. the style of propeller trailing edge cutting and shave on the pressure surface is adopted. the propeller ' s actual effect pitch will be reduced which cause the propeller ' s torque down
本文主要是考慮螺旋槳出現負荷過重時如何處理的問題，所以採用槳葉隨邊切割並在葉面處將翼型修順的方式，實質上是切割后導致螺旋槳實效螺距的減小，從而使螺旋槳吸收的轉矩降低來達到主機負荷降低的目的。
