摘 要: 分析了风机作用下气垫车辆的垫升机理,针对试验样车的垫升需求,以流量、全压、功率以及各种无因次特性参数为指标对风机进行了选型与计算,并计算了气垫车辆的理论飞高。最后通过风机性能试验对比了所选风机的理论与实际工作特性,验证了风机系统设计与选型的合理性。 The flying mechanism of the air-cushion vehicle is analyzed which is lifted through a fan. In accordance with the flying need of test vehicle, flow rate, total pressure, power and several parameters without any dimension needed is used as the guide lines to choose the proper fan, and the theory flying height of the vehicle is calculated. Finally the theory and actual working characteristics of the fan are compared through the working performance test of the fan, which validates the rationality of fan system choice and design.
