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

摘要

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 has been implemented and validated with different test cases. Different approaches for beam model generation have been investigated and a calibration process using optimization has also been put in place and tested on transport aircraft configurations. This work makes it possible to carry out accurate aerodynamic analyses taking static aeroelastic effects into account.
