摘　　要：为了更真实地模拟机翼副翼受控偏转运动,以二维带副翼的机翼为例,运用动态重叠网格技术耦合求解受比例—积分—微分(proportional integral derivative,PID)反馈控制的副翼偏转过程中的非定常NS(navier-stokes)方程,获取了副翼偏转过程中的流场特性。首先利用动态重叠网格求解算法和Fluent软件包模拟了NACA0012翼型的定常气动特性和非定常气动特性,然后利用动态重叠网格求解算法对受PID控制的二维机翼副翼偏转过程进行了数值模拟。结果表明,该数值模拟方法可靠有效,能够为控制算法的设计提供参考,并能够反映副翼受控运动的非定常流场时序变化,初步建立了二维机翼副翼受控运动模拟与机翼流场求解相结合的直接数值模拟方法,为更真实地模拟运动物体的流场特性提供了一种动态求解算法。In order to more realistically simulate the controlled deflection motion of ailerons,two-dimensional aileron as an example was studied.The dynamic overset grid technology was used to coupled solve the unsteady NS(navier-stokes)equation in the aileron deflection controlled by proportional-integral-derivative(PID)feedback.The flow field characteristics during the aileron deflection were obtained.Firstly,the steady and the unsteady aerodynamic characteristics of the NACA0012 airfoil were simulated by using the dynamic overset grid solution algorithm and the Fluent software.Then,the dynamic overset grid solution algorithm was used to perform the PID-controlled two-dimensional aileron deflection motion.Numerical simulation results show that the numerical simulation method is reliable and effective.This method can provide a reference for the design of the control algorithm and reflect the unsteady flow field sequence changes of the aileron-controlled motion.A direct numerical simulation method combining two-dimensional aileron controlled motion simulation and wing flow field solution was initially established,which provided a dynamic solution algorithm for a more realistic simulation of the flow field characteristics of moving objects.
