气垫船围裙-气垫系统气弹与水弹动力设计原理

Skirt of hovercraft-Design principles for aeroelastic and hydroelastic dynamics of air cushion system

根据响应围裙-气垫系统的动力学分析，气垫船柔性围裙可简化为一个气弹和水弹动力反馈系统。由此导出的一些基本概念和判据可直接应用于气垫船阻力、稳性和耐波性的优化设计。根据该理论研制的新型高让浪性响应围裙系统、开发的低阻抗气垫系统优化设计技术和多功能气道被动放气技术成功应用于×××型舰载气势登陆艇上，在×××型侧壁气势交通艇上也首次成功应用响应围裙首尾气封。

According to the dynamic analysis of the responsive skirt-air cushion system, the flexible skirt of the hovercraft can be simplified to a aeroelastic and hydroelastic dynamic feedback system. The basic concepts and principles derived on this base can be used directly to optimized design of hovercraft resistance, stability and sea keeping quality. The new type high wave-vielding responsive skirt system, newly developed low-resistance cushion system design optimizing technology and multi-function passive type air duct releasing technology developed on the basis of this theory have been successfully used for the new type air cushion landing boat. Also the responsive bow and stern sealing skirts have been successfelly used for the first time on a side-wall surface effect crew boat.
