摘要
近年出现了多种结构新颖、性能先进的垂直起降无人机,多以升力风扇作为升力装置;升力风扇作为直接升力装置,拥有诸多新特点。简单介绍了升力风扇工作过程,在此基础上建立起升力风扇基本分析模型,并对该模型进行了深入的分析讨论,得出了一些表征升力风扇基本特性与其核心部件风扇之间内在关联的规律;最后据此模型初步设计出一升力风扇,并对其进行数值模拟计算,结果表明该模型具有很高的准确性与实用性。
In recent years,lift fan as the direct lift device,has been widely used in various types of VTOL UAV,which have novel structure and advanced performance.Considering the new features of lift fan,the working process of the lift fan was simply introduced,and a basic analysis model was established for lift fan.After a thorough analysis and discussion on the model,some conclusions were obtained which reveal the internal relationship between the basic characteristics of lift fan and the characteristics of fan,core component.Finally,a lift fan was preliminary designed based on this model,and studied with numerical simulation.The calculation results show that this model has high accuracy and practicability.
