propeller slipstream meaning in English
螺旋桨滑流
Examples
- Based on the mechanism of slipstream interaction , described in this thesis is firstly the interaction of the propeller slipstream with the wing 、 fuselage and horizontal tail . subsequently , the changes in lift 、 drag and pitching moment are derived , giving an engineering model for the prediction of the increments in the aerodynamic characteristics caused by the interference between the propeller slipstream and the other parts of aircraft . this method offers a powerful means to the calculation of the aerodynamic interaction between the propeller and the aircraft , providing reliable data for the design of and aerodynamic calculation on propeller - powered aircraft
本文以滑流干扰的机理为出发点,研究了螺旋桨滑流与飞机机翼、机身、平尾组合体之间的相互影响,推导出滑流引起的飞机升力、阻力和俯仰力矩的变化,给出了滑流干扰对机体气动特性影响的工程估算方法,为研究螺旋桨与飞机部件之间的相互干扰提供了有力的工具,为以螺旋桨发动机为动力的飞机的设计和气动计算提供可靠的依据。 - Compared to an ordinary rudder , the value of lift coefficient of ichthyoid rudder is about 30 % higher and the maximum rudder angle of it nearly reaches 45 degrees . ichthyoid rudder is a design under such a conception as to effectively utilize the propellers slipstream for rudder action , and featured by having a fish - shaped one - piece construction that is to say - no part of ichthyoid rudder can move in the water
其研究的鱼形舵是一个没有在水下移动的鱼尾形剖面单片结构，增加了全舵的剖面拱度，使螺旋桨尾流的折射水量增强，进而增大了水动力的作用，使之比普通流线形舵的升力提高30左右。
