Steady/Unsteady Aerodynamic Optimization Design of Airfoil Based on Discrete Adjoint Method
In order to improve the aerodynamic performance of an airfoil effectively,a method of the steady/unsteady aerodynamic optimization design based on discrete adjoint method has been developed.This method is applied to study the inverse design problem of an airfoil under a given target pressure and the optimization problem of time-averaged drag of an oscillating airfoil.The results show that the geometry of the inverse design airfoil is highly consistent with the target airfoil;after 12 iterations,the time-averaged drag of the oscillating airfoil is reduced by about 40％.
