一种穿浪双体船纵向运动姿态控制方案设计

A Scheme Design for WPC Longitudinal Motion Attitude Control

本文根据穿浪双体船在波浪中高速航行时纵摇和升沉运动剧烈这一问题,提出了在穿浪双体船的每个单体艏部加装水翼系统,水翼上附加可控式襟尾翼;在每个单体的艉部加装可控式压浪板的方案来改善穿浪双体船的纵向运动姿态稳定性。首先基于穿浪双体船的航行特点,给出了水翼和压浪板的电伺服系统总体结构方案。然后,考虑水翼和压浪板系统间负荷的分配方案,给出了水翼和压浪板系统几何特性确定方法。在此基础上,分析了水翼和压浪板在不同几何特性下的水动力性能,寻求一种适合穿浪双体船的水翼翼型和压浪板安装高度的最佳方案。本文所提方案对其它高性能船舶或舰艇也有一定的参考价值。

Aimming at severe pitch and heave motion of WPC when sailing in the seawave with high speed,a scheme that a hydrofoil with controllable flap hydrofoil is installed at the bow and a controllabl e stern flap is installed at the stern of WPC for each monomer is proposed in this paper to improve the longitudinal mot ion attitude stability of WPC.Firstly,the overall structure schemes of electric servo system for hydrofoil and stern flap system is presented based on WPC navigation characteristics.Then,the geometry feature design method of hydrofoil and stern flap system is addressed by considering load distribution between hydrofoil system and stern flap system.Lastly,the hydrodynamic performance of hydrofoil and stern flap is analysed to find a optimal scheme of hydrofoil aerofoil and stern flap installation height that fits to WPC.The scheme proposed also have some reference value for other high-performance ship or warship.
