At first the form of the turbine blade has been analysed under the theory of aerodynamics and the angle kept tranformation of complex variable function, and thus the analytic formula of pneumatic moment has been deduced . meanwhile the analytic approach to function extremum being employed, the optimal installing angle of the jet has been gained, and the output power as well as the pneumatic efficiency has been analysed 通過空氣動力學(xué)的理論,采用復(fù)變函數(shù)的保角變換,從理論上分析了渦輪葉片的形式,導(dǎo)出了風(fēng)動轉(zhuǎn)距的解析表達式,并采用函數(shù)求級值的解析方法,求得了噴嘴的最佳安裝角度,分析了風(fēng)動渦輪的理論輸出功率和風(fēng)動效率。
