分析了“拉”模型单作动器模式下，微射流作动器的入射角度、驱动频率、速度幅值及与主射流间的距离对主射流偏转程度的影响，并确定了作动器工作参数的最佳范围;分析了“拉”模型双作动器模式下，不同的相位差对主流偏转程度的影响。 - This method makes it possible for investigating the unsteady nonlinear potential flow in a complicated environment with higher efficiency . the aerodynamic forces of a wing in couple motion of heave and pitch with ground effect are analyzed in detail based on the numerical result . it is shown that a thrust force exists when the wing is in heave motion
深入系统地分析了存在表面效应时机翼运动规律和气动力之间的关系，研究结果表明，机翼升沉运动产生的推力与升沉速度幅值的平方成比例，推力和推进效率和振荡频率成反比；机翼的俯仰运动可以调节推力和推进效率，但是单纯的俯仰运动不会产生推力。
