Abstract

DLR numerically analyzed the aerodynamic performance of the wing design of the European Supersonic Commercial Transport aircraft (ESCT) at subsonic, transonic and supersonic Mach numbers. This work is part of the EUROSUP program and defined in tasks 3 and 4. The DLR-Navier-Stokes flow solver FLOWer, with the algebraic Baldwin-Lomax turbulence model (with Degani-Schiff extension), and the k-w two equation turbulence model, was used for this work. Experimental force and pressure distribution data are available for all investigated onflow conditions. Additionally the numerical accuracy of the flow solutions is investigated and an analysis of discretization issues is presented. The viscous lift, drag and pitching moment values at all onflow conditions are predicted in good agreement with experimental results.
