摘　　要：气垫船通过垫升风机产生气流,经由围裙通道,向船底气室供气,依靠气垫产生的垫升压力以支撑船体悬浮于水面或地面航行,以此减小船体和接触面之间的阻力、大航速可调范围,使其具有极高的机动性。根据某型号气垫船用垫升风机的设计要求,针对玻璃纤维复合材料叶片开展铺层设计、强度计算、模态计算及强度试验等方面进行了研究。研究表明:采用玻璃复合材料的叶片可以达到轻量化的要求,应力计算和模态计算结果均满足使用要求,使用过程中不会破坏也不会发生共振。通过强度试验验证在极限转速情况下最大应变值为2 747με,远小于材料的应变极限,叶片未发生破坏。Air-cushion vehicle(ACV)generates airflow through lift fans,which supply the air chamber airflow through the apron passage,supporting the hull suspended in the water or on the ground to navigate by air cushion pressure,for the purpose of reducing resistance,increasing speed and imparting ACV with high mobility.This article proposes a comparative study on Ply design,strength calculation,modal calculation and strength test based on the design parameters of a certain type of hovercraft lift fan blades.The results show that:the blades made with glass fiber composite materials through a special process can meet the requirements of lightweight.The stress calculation and modal calculation results meet the usage requirements,and there will be no damage or resonance during use.The strength test result shows that the maximum strain value under extreme speed is 2747με,far below the strain limit of the material,there is no damage to the blade.
