摘　　要：T型翼因其优秀的减纵摇特性被广泛应用于船舶工程领域,但T型翼在工作时所产生的升力远小于船舶的回复力矩,制约了T型翼减摇效果。文中提出在T型翼的吸力面装配涡流发生器(VGs),为船体提供更大的升力。通过探究VGs对翼型失速时升阻力系数及流场的影响,证明VGs可增加翼型的最大升力系数,延迟翼型失速,有效减小阻力。对滑行艇母船和滑行艇在常规T型翼/大升力T型翼的水动力性能进行数值模拟,得到安装大升力T型翼后的滑行艇整体升力比安装常规T型翼后的滑行艇整体升力提高18%,阻力减少17%。通过加装大升力T型翼前后船体阻力以及运动预报响应对比,验证了大升力T型翼的应用效果。T-foil is widely used in the field of ship engineering because of its excellent anti-pitching characteristics.However,the lift generated by the T-foil at work is much smaller than the restoring moment of the ship,which restricts the anti-rolling effect of the T-foil.In this paper,it is proposed to install vortex generators(VGs)on the suction surface of the T-wing to provide greater lift for the hull.By exploring the influence of VGs on the lift-drag coefficient and flow field during airfoil stall,it is proved that VGs can increase the maximum lift coefficient of the airfoil,delay the airfoil stall and effectively reduce the drag.The hydrodynamic performance of the planing craft mother ship and the planing craft in the conventional T-wing/high-lift T-wing is numerically simulated.The overall lift of the planing craft after the installation of the high-lift T-wing is 18%higher than that after the installation of the conventional T-wing,and the resistance is reduced by 17%.By comparing the hull resistance and motion prediction response before and after the installation of the high-lift T-wing,the application effect of the high-lift T-wing is verified.
