摘　　要：为研究升力风扇的结构布局,并探索1种新结构布局方案设计方法,归纳了4项升力风扇结构布局的特别设计需求,由此引出4个方面关键结构特征,并基于结构特征的组合设计了多种各具特点的结构布局方案,最终通过多方案对比分析,从中选定双承力机匣对转无静叶方案。设计结果表明:采用关键结构特征组合的方法有助于布局方案的创新设计,并能够形成系列化方案,从而为创新型项目的风险控制提供方案支持。In order to analyze the structure layout of lift fan and find a design method for a new structural layout design, four special requirements of the lift fan structural layout were concluded from the plan of the power system, key structural features of the lift fan structural layout were analyzed in four aspects, and based on the structure characteristics of the combination of characteristic, variety of structural layout scheme were designed. Eventually, after compared and analyzed of various plans, ＂Two Supporting Frame No stator＂ layout was selected to be the best. Design results show that adopt the method of critical structural features combination is helpful for creative structural layout design. And this method could also give a series of structural layout to support the risk control of the creative programs.
