某陆空汽车涵道风扇有限元分析

Study on Ducted Fan of Flying Vehicle Based on Finite Element Theory

针对在陆空汽车起降以及平飞状态的不同工况,根据螺旋桨的动量理论,计算得到涵道风扇桨叶有限元分析的边界条件.在限元软件ANSYS中建立采用层铺设计的涵道风扇桨叶有限元模型,并对涵道风扇桨叶添加边界约束条件、进行了分析计算.结果表明,该采用层铺设计的涵道风扇设计方案能够满足陆空汽车各飞行工况强度要求,为陆空汽车升力原件设计提供了可行方案.

Based on the aerodynamics, the limited stations used in the finite element analysis of different working conditions of the flying vehicle. The model of the layering designed ducted fan was built in ANSYS. The vertically take-off and landing and flying conditions are simulated. The vertically take-off and landing and flying conditions are simulated.
