摘　　要：全垫升气垫船动力和阻力的计算和匹配问题的研究是其设计前期阶段的关键。基于STAR-CCM+流体计算平台和滑移网格模型分别对空投气垫船水面航行过程和螺旋桨气动特性进行了数值模拟,得到不同航速下的航行阻力和螺旋桨推力数据,综合分析研究了两者的匹配性问题。研究结果表明:兴波阻力随航速变化趋势和阻力峰出现位置均与相关文献和试验数据吻合,验证螺旋桨的推力计算结果与试验误差在6%以内,验证了CFD方法对气垫船航行阻力及螺旋桨动力模拟计算的可行性与有效性;将2款待选用的四叶和三叶螺旋桨气动性能与航行阻力匹配分析后,在发动机极限性能转速下,三叶螺旋桨能达到更高的最大航速,以20节速率巡航时,三叶效率更高,同时质量轻15%,综合说明三叶螺旋桨性能更佳。研究结果为该型气垫船的设计和选型提供重要的理论依据与数据支撑。The study on the calculation and matching of the power and resistance of the hovercraft is the key in the early stage of its design.Based on STAR-CCM+fluid computing platform and sliding grid model,the surface navigation process and propeller aerodynamic characteristics of air dropped Hovercraft are simulated respectively.The simulations provide data on the navigation resistance and propeller thrust at different speeds,and a comprehensive analysis is performed to investigate their matching relationship.The study results show that the wave-making resistance exhibited a changing trend with the speed and the location of the resistance peak aligned with relevant literature and experimental data.The calculated propeller thrust is verified to have an error of less than 6%compared to experimental results,confirming the feasibility and effectiveness of using computational fluid dynamics(CFD)methods for simulating the navigation resistance and propeller dynamics of air cushion vehicles.After conducting a matching analysis between the performance of two candidate propellers,a four-blade and a three-blade propeller,with the navigation resistance,it is found that at the engine’s maximum performance speed,the three-blade propeller could achieve a higher maximum speed.When cruising at a speed of 20 knots,the three-blade propeller exhibits higher efficiency and was 15%lighter,indicating superior performance.Thus,the study demonstrates the better performance of the three-blade propeller.The study results provide important theoretical basis and data support for the design and selection of this type of hovercraft.
