介绍美国气垫登陆艇推进垫升系统在三十余年使用过程中遇到的问题及解决措施.随着艇装载量、耐波性、全寿命周期维护等总体性能和作战使用要求的提高以及主机功率不断增大,结合现代技术分析手段,推进垫升系统正不断改进优化.在广泛采用新技术及复合材料后,艇载重大量幅增加且耐波性有所提高.%This paper introduces problems of propulsion lift system on US hovercraft and their solutions during operation in the past 30 years. It shows that the propulsion lift system is being developed by the advanced technical analysis method, resulting from the heightening requirement of combatant capability, increasing main engine power, and improving overall performance, such as shipborne load capacity, seakeeping capability, and lifespan maintenance. The propulsion lift the fan of the new ship-to-shore connector has been reduced to one per shipboard. The arrangement of the propulsion lift system is totally new with longitudinal main engine layout, simplified shafting system, double speed reduction gearboxes and more clutches in order to improve the ship availability under the condition of the either engine failure. The wide adoption of the advanced techniques and the compound material results in the greatly increased shipborne load capacity and the improved seakeeping capability.
