侧壁气垫船的稳性研究

A study on the stability of the side-wall air-cushion craft

本文提出了侧壁气垫船在倾斜时的稳度力短（臂）的计算方法，包括合理而方便的近似计算法。对于校核稳性必需的横摇角，通过分析船模棱摇试验资料，得到与常现双体船相近的公式，所不同的是要引进气垫参数压长比Pc／Lc的修正。

A method as well as a rational and convenient approximation for the stability moment (stability arm ) calculation of sule-wallair-cushion craft on inclined condition is proposed in the paper. Through analysis on the rolling test data of model, a calculationformula for the allowable maximum rolling angle of side-wall air-cushion craft to satisfy the requirement in stability checking is obtained. The formula is similar to that of the conventional catamaran, but some of the coefficients should be corrected with air-cushion parameter Pc/Lc(pressure-Length ratio)
