水动离心力及其应用
Hydrodynamic centrifugal force and its application
【摘要】 针对常规船艇在高速前进时转弯易失去稳定性,继而出现向心倾覆的危险,提出在船底浸湿面设置一对平行对称于船底纵向中心线的导流槽、且在船舷设置压浪阻溅流挡板,从而使船艇转弯时能激起足够强大的水动离心力、水动推进力、水动升力和相应的水动抗船体向心倾覆扶正力矩、水动助回转力矩。依据上述理论和实船、实航的试验结果,证实设置涌浪导流槽和挡板后形成的这些水动力和相应的水动力矩能使船艇在转弯时既保持机动灵活,又能高速稳定与安全。
【Abstract】 By aiming at the hazards of centripetal overturn due to the stability loss when the vessel is turning with high forward speed,this paper proposes to set a pair of symmetrical diversion trench parallel to the longitudinal central line on the bottom wetted area,and fit trimming flaps at the shipboard,so as to arouse strong enough hydrodynamic centrifugal force,hydrodynamic propulsive force,hydrodynamic lift and corresponding hydrodynamic opposing the hull centripetally overturn righting force moment as well as hydrodynamic quickening turn force moment.The theory and results from ship trial have proved that these hydrodynamic forces and corresponding hydrodynamic force moments can make the ship turn not only with small turning radius but also flexibly,stably and safely.
