摘　　要：运用计算流体力学方法验证鸭式布局的增升原理及其应用于水下滑翔机的可行性。对安装鸭翼的模型和原模型在水池中进行拖曳试验,验证了鸭翼的增升性能。试验表明,当鸭翼安装在主翼面上方时只能改善正攻角运动时的升阻性能,而负攻角运动时的升阻性能没有改善,甚至变差。论文提出一种可改变垂向位置的鸭式布局,在正攻角运动时鸭翼位于主翼面上方,而在负攻角运动时它位于主翼面下方。通过仿真计算验证了方案的可行性。这项研究表明,在定常滑翔运动时,可变鸭式布局能有效提高水下滑翔机的升阻性能,改善滑翔性能,对鸭式布局进一步应用于水下滑翔机有一定借鉴意义。Computational fluid dynamics is applied to verify the principle of increasing lift for the canard configuration,and application feasibility of the canard configuration in underwater gliders.Towing tank experiments of the model with canard wing and the original model were carried out to verify the lift increasing performance of the canard configuration.The experimental results show that the canard wing installed above the main wing can improve the lift-drag performance only at positive incidence,and even worse at negative incidence.A variable canard configuration by changing the vertical position is proposed.The canard wing will be arranged above the main wing surface when moving at a positive incidence,and below the main wing surface when moving at a negative incidence.Feasibility of the scheme is verified by numerical simulation.It is shown that the variable canard configuration can effectively improve the lift-drag performance and improve the gliding performance of the glider at a complete gliding cycle.Research results may provide a reference for the subsequent application of canard configuration to underwater glider.
