The rudder blade is semi-balance, double plate, stream-line type. Able to turn to 350 rudder Angle at port and starboard side.
舵叶为半平衡式双板流线型结构，可分别向左右回转350舵角。

And the two-dimensional shock-wave relations of the stream-line coordinates are also derived as the shock wave may be exist in transonic flow field.
由于在跨音速流场内可能存在激波，所以也导出了流线座标系二维激波关系式。

It makes the application of the mean-stream-line method in large space cascade design possible with the optimized given velocity distribution along suction surface also guaranteed.
