| 摘 要： | 在固连于螺旋桨桨叶的非惯性坐标系中,对大展弦比叶片的螺旋奖建立了升力线模型。在匹配渐近展开法分析中引入一假想速度位,导出固连坐标系中的控制方程、边界条件和Ｂｅｒｎｏｕｌｌｉ方程。由匹配渐近展开法的分析表明,在螺旋桨的进距比不是太小的情况下,螺旋桨的升力线理论在固连于螺旋桨桨叶的非惯性坐标系中仍然成立。

| Abstract: | Lifting line model has been developed for propeller of large aspect ra tio in blade-at-tached noninertial system,In the analysis of the method of matched asymptotic expansions,ficti-tious velocity potential is introduced.Control equation, boundary condition and Bernoulli equation are derived in blade-attached system. The analysis of the matched asymptotic expansions shows that if the advaneed ratio of propeller is not very small,lifting line theory itq still valid in blade-at-tached noninertial system for propeller. |
