摘　　要：气垫船空气螺旋桨导管结构受力复杂,对重量控制要求高,且目前国内缺乏相应的设计规范和标准。据此,结合国内目标中型气垫船导管特点分析,基于典型导管气动力特性模型试验、CFD理论计算、经验公式估算和实艇测试等方法开展了中型气垫船导管内蒙皮脉动载荷预报方法研究。研究成果可分别为中、大型气垫船导管结构设计提供技术支撑和参考。It is difficult to design the duct structure of an ACV because of its complex loads, strict control of weight and lacking of design criterions and standards nowadays. Therefore, forecasting methods for fluctuating pressure of typical propeller duct＇s inner surface in medium-size ACV are developed based on the characteristics analysis of propeller duct used in a typical medium-size ACV, dynamic model experiment of the ducted propeller, theoretical calculation with CFD, empirical formukl estimating and shipboard measurement. Results of the study can provide technical support and reference to propeller duct structure design.for medium and large-size ACV respectively.
