Abstract

An efficient inverse design method based on the MGM(Modified Garabedian-McFadden) method has been developed. The 2-D Navier-Stokes equations are solved for obtaining the surface pressure distributions and coupled with the MGM method to perform the inverse design. The MGM method is a residual-correction technique, in which the residuals are the difference between the desired and the computed pressure distribution. The developed code was applied to several airfoil shapes and the propeller. It has been found that they are well converged to their targeting shapes.

본 연구에서는 MGM(Modified Grrabedian-McFadden)방법에 기초한 효율적인 역설계 방법을 개발하였다. 표면압력 분포를 얻기 위해 2-D Navier-Stokes 방정식을 풀었고, 역설계를 수행하기 위해 MGM방법을 사용하였다. MGM 방법은 설계 목적 압력분포와 Navier-Stokes 방정식에서 계산된 압력분포의 차인 잔여량을 보정하는 잔여-보정 기법이다. 코드 개발을 위하여 몇몇 익형과 프로펠러 형상설계에 적용하였다. 이들 모두 목표하는 형상에 잘 수렴해 갔다.
