Abstract | |||||||||
| Under the framework of the DLR-CAE cooperation topic: 92-16, numerical investigation is carried out on two transonic airfoil analysis/design codes at the Institute of Design Aerodynamics, DLR, Braunschweig. The first is the DLR Airfoil Design Method based on the solutions of the Euler/Navier-Stokes eqs., and the other is the ISES Transonic Airfoil Analysis/Design code of MIT, which uses the Euler eqs. with viscous correction. This report summarizes the analysis part of the investigation where a DLR-2D Euler/Navier-Stokes code, which is the analysis part of the DLR Airfoil Design Method, is compared with ISES, running in direct mode, through numerical computations on several airfoils in inviscid and viscous flow conditions. | |||||||||
