一种崭新的船舶运行原理

这是一项原理性的发明,已获得22个国家的发明专利.该发明提出一种特别的船体浸湿面外形布局,可在不改变原推进系统及其推进功率的情况下,大大提高船艇的性能:船艇前进时激起水动推进力、附加水动升力和相应的水动力矩,从而大幅度提高航速和航向、横向、纵向的安全稳定性;转弯时激起水动助回转力矩和抗船体横向向心倾覆力矩,使船艇可以很小的回转半径和横向倾侧,安全迅速地完成回转;迎浪前进时激起水动反冲击力、附加水动升力和相应的水动力矩,可以抗颠簸失速、纵摇拍击和横摇摆动,使船艇平稳高速地前进,平稳安全地完成回转.应用该原理建造的小型船艇的实航试验证明了其确实具有上述性能.

A new principle of vessel motion

This paper presents a principled invention which has gained patent in 22 countries. The invention puts forward a specific shape of wetted area of the hull. On condition that the propulsive system and its propulsive power are unchanged, the performance of the vessel can be greatly improved. When the vessel is moving forward, the hydrodynamic propulsive force, additional hydrodynamic lift and corresponding hydrodynamic force moments are aroused. Then the vessel speed will be greatly heightened, and the stability and safety of the course, lateral and longitudinal direction will be greatly improved. When the vessel is turning, the hydrodynamic force moment to quicken turning and the force moment opposing the lateral centripetal overturn of the vessel will appear, that make the vessel finish turning with small turning radius and small lateral inclination of the hull. When the vessel is facing wave forward, the hydrodynamic contra-impact force, additional hydrodynamic lift and corresponding hydrodynamic force moments are aroused, which oppose to jolt, speed losing, rolling and pitching and make the vessel move forward smoothly with high speed, stability and safety and finish turning with stability and safety. The navigability test of the small vessels constructed according to the principle proves that they actually have the above performances.
