The theoretical calculation method about how to predict the hydrodynamic characteristics of ichthyoid rudder is proposed in this paper
本文提出了一種魚形舵定常升力的水動力性能預報的理論預報方法。 -
In addition, the data needed to survey and the equation concerned is given. the elements that affect the hydrodynamic characteristics of ichthyoid rudder are analyzed
在試驗設計部分，給出了魚形舵敞水試驗的具體思路，有關設備、裝置，需要測量的主要數據，處理數據所要用到的主要公式等。 -
In the first part, the steady nonlinear vortex lattice method is adopted to calculate the hydrodynamic characteristics of open water ichthyoid rudder, and the induced velocity of ichthyoid rudder is calculated using panel method
本文理論計算部分，採用定常非線性渦格法計算魚形舵的水動力性能，用面元方法計算舵流場的誘導速度。 -
The results of the lift interference are given here as a result of a series of rudder of different aspect ration fitted to different location of the fornication. in the second part, the device of open water experiment of ichthyoid rudder is present
提出了一個估算魚形舵定常升力的方法，計算了一系列不同展弦比、不同翼型、不同位置分叉點及尾緣剖分角對魚形舵影響下的升力。 -
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
其研究的魚形舵是一個沒有在水下移動的魚尾形剖面單片結構，增加了全舵的剖面拱度，使螺旋槳尾流的折射水量增強，進而增大了水動力的作用，使之比普通流線形舵的升力提高30左右。
