Simulation of heaving and pitching motion of fast boat with hydrofoils;2. High-efficient flap type rudders with 45°dip angle are installed in order to control the course, rolling and pitching simultaneously.

采用45°倾斜安装的高效襟翼舵实现航向、横摇、纵摇的同时控制，阐述了斜舵减摇原理，并提出了采用高效襟翼舵以获得较高的升力系数，从而在不加大舵面积的情况下实现船舶纵摇运动控制。

The thrust coefficients and propulsive efficiency of a two-dimensional flexible fin with heaving and pitching motion were computed using FLUENT. The effect of different locations of the pitching axis on propulsive performance was examined using three deflexion modes which are respectively, modified Bose mode, cantilever beam with uniformly distributed load and cantilever beam with non-uniformly distributed load.

利用FLUENT软件数值计算了二维柔性鳍作升沉纵摇运动时的推力系数及推进效率，探讨了修正Bose变形方程、均匀载荷和非均匀载荷悬臂梁变形方程等三种柔性模式下纵摇轴位置对摆动鳍推进性能的影响，其中纵摇轴在尾缘处能够获得更大的推力，而最高的推进效率分别对应修正Bose模式下纵摇轴距首缘1/3弦长处和悬臂梁柔性变形模型下纵摇轴距首缘2/3弦长处。

Results show that in hover the fuselage normal force and pitching moment are relatively high due to the influence of rotor/wing downwash; and in low speed forward flight, the downwash have strong interaction on the normal force and pitching moment of fuselage due to the big dimension horizontal tail; the effects of downwash on the fuselage rolling and yawing moments are little and the influence on fuselage side force is considerable.
