Numerical Simulation of the NASA High-Lift Trap Wing with the elsA CFD Software

Autor: Ludovic Wiart, Frédéric Moëns

Publikováno v: Scopus-Elsevier

The ONERA has been involved in the first AIAA CFD High Lift Prediction Workshop from the beginning. Within this frame, a certain amount of aerodynamic calculations have already been carried out on the NASA Trap Wing geometry using the ONERA elsA CFD

Accounting for Wing Flexibility in the Aerodynamic Calculation of Transport Aircraft Using Equivalent Beam Model

Autor: Ludovic Wiart, Gérald Carrier

Publikováno v: 13th AIAA/ISSMO Multidisciplinary Analysis Optimization Conference.

In order to perform accurate aerodynamic calculations, the influence of the flexible wing deformation has to be taken into account. A platform coupling the elsA CFD solver with a simplified model of structure based on Euler-Bernoulli beam equations h

Development of NOVA aircraft configurations for large engine integration studies

Autor: David Hue, Bernard Paluch, Richard Grenon, Olivier Atinault, Ludovic Wiart

Publikováno v: Scopus-Elsevier

The search for reduced fuel consumption of future transport aircraft involves an improvement of the propulsive efficiency. The current trend for engines is toward lower fan pressure ratio (and higher bypass ratio), which has to be compensated by larg
