摘    要:提出在映象坐标下求解二维非定常欧拉方程获取二维振荡机翼的气动反命题解,给出了非定常气动反问题的边界条件和求解方法.该方法克服了以往基于势函数方程解反命题的局限,统一了亚音、跨音与超音流反问题的解法,并避免了非定常尾涡面的直接求解与反问题未知边界的不确定性.

关 键 词:非定常反问题  振荡机翼  欧拉解法

Abstract:A new method for inverse problem of two dimensional unsteady flow around oscillating airfoils is proposed, by solving unsteady Euler Equations in mapping coordinates. The unsteady boundary conditions and the schemes to solve unsteady inverse problem are given. The approach can unify the subsonic, transonic and supersonic inverse problems and avoid the direct simulation of the unsteady wake of oscillating airfoil. The problem about the uncertainty of airfoil geometry is settled by coordinate transformation in the paper.
Keywords:unsteady inverse problem  oscillating airfoil  unsteady Euler equations
