桨后整流支架的设计方法

简要分析了桨后整流支架的特点及其一般设计原则，以及基于动量理论、叶素理论和理想螺旋桨理论阐述了桨后整流支架的设计方法，最后给出了一个基于该设计方法的设计实例，并将本设计方法的计算结果与试验结果进行了分析比较，进一步验证了该方法的可行性。

A design method of exit vane in rear of ducted propeller

The advantage and common design principle of exit vane in rear of ducted propeller is discussed in the paper.Then a design method of exit in vane of rear ducted propeller is expatiated on the basis of momentum theory,blade element theory and ideal propeller theory.At last,a practical sample is presented to analyze the difference between the computational result of design method and test result,validating the practicability of the design method.
