摘要
螺旋桨是目前水空两用装备动力推进的主要形式,能使装备多次完成水/空运动的切换。为快速得到最大效率时螺旋桨的几何特性,为螺旋桨详细设计提供数据输入,本文基于动量叶素理论,并通过与翼型升阻力系数快速计算的XFOIL程序进行融合,开发出水空两用对转螺旋桨快速设计程序。通过与文献结果对比及进一步分析,该螺旋桨快速设计程序可靠,最大相对误差不超3%。该程序可为水空两用对转螺旋桨详细设计提供预先输入,加快设计进程。另外,根据设计程序计算结果以及单排桨与对转桨间的效率关系,开展对转螺旋桨风洞试验,效率可达75%。该快速设计方法为后续一系列对转螺旋桨试验研究做准备,并提供生产加工相关参数。
Propeller is currently the main form of power propulsion for this kind of equipment, which could let the equipment complete multiple water/air navigation switching. To get the propeller geometrical characteristics under the maximum efficiency condition rapidly to provide the data-input for propeller detailed design, the rapid design software for waterair dual-purpose contra-rotating propeller is developed, which is based on blade element momentum theory and the integration of XFOIL software for the rapid calculation of the airfoil lift-drag coefficient. Via the comparison with the literature results and the further analysis, the software designed is reliable and the maximal relative error is less than 3%. This software could be employed to provide the advance input for the corresponding detailed design to accelerate the design progress. Besides, the water-air dual-purpose contra-rotating propeller wind tunnel experiments are performed according to the calculated results got by the designed software and the relationship of the efficiency between single-row propeller with contra-rotating one. The efficiency is 75%. This rapid design method makes preparations for the followed experimental investigations of a series of propellers and provides related parameters for manufacture.
