摘 要
随着社会的发展，私家车越来越多的涌入普通家庭，但是交通阻塞拥挤日渐突出，在我国尤为凸显，特别是不可持续发展能源过度利用，给环境带来了很大的危害。面对这样的问题，采用将电动汽车与直升飞机结合起来，也就是电动飞行器，将可以缓解交通阻塞拥堵以及能源过度利用的不足。本设计的主要任务是螺旋桨的设计，包括螺旋桨的支撑机构、传动机构、涵道的设计以及总体校核。

ABSTRACT
Along with the social development, the private car more and more flows out into common family, but the traffic jam hustles gradually outstanding, at our country in order to highlight, especially can not keep on to develop energy excesssive make use of, brought environment very great harm.Face a problem like this, the adoption puts together dynamoelectric car and helicopter knot, is also a dynamoelectric aircraft, will be able to alleviate the traffic jam hug to block up and the energy excessively makes use of of shortage.The main task of this design is the design of propeller, include propping up of propeller organization, spread motive to reach, design and total pit in the school of Han way.
