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.
