Environmental Friendly Transport Aircrafton. Increased transport capacity is achieved by enhancing takeoff and landing performance in order to reduce the separation between subsequent flights. Additionally, overall productivity is improved by adapting the configuration to future noise restrictions allowing for extended daily operating time

Application of fast and advanced CFD for high-lift configuration design tasksnumerous design modifications as well as advanced methods capable to predict the complex flow around a complete aircraft in high-lift configuration are part of the design process. Examples for the application of CFD-tools suitable for the respective design task are presented, i.e. 2D-contour design

DLR Contributions to Code Validation Activities within the European High Lift Project EUROLIFTFT is outlined. For the code assessment the DLR capabilities with respect to block-structured and Chimera grid generation for 2D and 3D high lift configurations are demonstrated, as well as to generate flow adapted hybrid unstructured grids for a 3D configuration. The corresponding results of 3D Nav

Calculation of attached and separated flow for a tailplane airfoil with rudder is investigated. Since the performance of this airfoil is strongly affected by the transition of the boundary layer, the calculations using the Spalart-Allmaras, . and . SST models are carried out with specified transition positions on the airfoil’s surface. It turns out, that the Navier-Stokes sol

Integrated Design of Installed Engine Nacelles Using an Inverse Design MethodLR Tau code, a finite-volume flow solver for the solution of the Reynolds-Averaged Navier-Stokes equations on arbitrary grids. The inverse design method is based on an iterative residual-correction type approach and attempts to generate a geometry which satisfies a user-prescribed target pressure di

Numerical Investigation of Wing-Nacelle Interference Effects at Transonic Flow Conditions for a Geneinitiated between DLR and ONERA. This paper presents preliminary numerical simulation results of steady flow phenomena occurring in the engine region of a generic aircraft configuration. Main issues of this project phase are parameter investigation and definition of a wind-tunnel model geometry whic
