摘要
本文研究了单体小水线面水翼复合型高速船 ( HYSWAS)翼航状态的运动稳定性。运用航空领域中的飞行器运动稳定性理论 ,推导了 HYSWAS翼航状态线化无因次小扰动运动方程及其特征方程 ,提出了基于特征根的运动稳定性评判方法及其品质指标 ,讨论了船舶惯性元素、运动导数以及吃水的变化对 HYSWAS翼航状态运动稳定性的影响 ,得出了几点实用的结论 ,为该船型的研究和设计提供了一定的依据。
Based on the research of dynamic stability of the hybrid hydrofoil small water area high speed ship (HYSWAS) and the dynamic stability theory applied to aerocraft in aviation and spaceflight, this paper develops the linearized non-dimensional equation of small perturbation motion of HYSWAS and its eigen equation on foil borne, and expresses the discriminance and quality criterion of dynamic stability based on the eigen roots, and discusses the influence that inertia factors, dynamic stability derivatives and drafts impact on the dynamic stability of HYSWAS on foil borne. Several practical conclusions are obtained, which provide an important reference for the research and design of HYSWAS.
