为设计出适用于平流层飞艇的螺旋桨,在叶素理论的假设下,通过分析叶素效率确定设计参数的取值范围,给出了平流层飞艇螺旋桨的初步设计流程。研究发现,在其他条件不变的情况下,提高桨叶拉力的方法有提高叶梢的周向速度或增加桨叶宽度;提高桨叶效率的方法包括降低叶梢的周向速度或增加桨叶的宽度。 In order to design a propeller suitable for a stratospheric airship, a preliminary design flow of a stratospheric airship propeller is given based on the theory of the leaf element theory, by determining the range of the design parameters by analyzing the efficiency of the elemental voids. The study found that, under other conditions remain unchanged, the method to increase the blade pull force to improve the blade tip circumferential speed or increase the width of the blade; to improve blade efficiency methods include reducing the blade tip circumferential speed or increase the blade The width of
