摘要
针对小型倾转螺旋桨独特的工作特性,在研究国外有关倾转旋翼桨叶设计现状的基础上,本文运用了遗传算法对桨叶的参数进行了寻优设计分析,以满足不同飞行状态的性能要求。设计结果表明,由本文提出的方法设计的螺旋桨与普通螺旋桨相比,在不损失巡航推进效率的同时,可显著增加悬停效率,提高飞机的悬停性能。
Considering the operational characters of tilt rotor/propeller,a design method for tilt rotor/propeller is presented.This approach,based upon axial flow blade element theory and genetic algorithms,can define the rotor/propeller blade design variables to converge on a best compromise that meets the desired hover/cruise performance requirements.The design results show that an improvement of hover performace without causing a decrease of cruise efficiency can be obtained by the method.
