Abstract

A multidisciplinary design analysis and optimization process is developed at ONERA for the design of Tube and Wing and Blended Wing Body aircraft configurations. This process is composed of numerous disciplinary modules (geometry, propulsion, aerodynamics, structure, handling qualities and flight mission), and the overall process considers different fidelity levels for the different modules at each step of the design process. This article describes the low fidelity aerodynamic module used during the preliminary design optimization process. Analytical formulations retained for lift and drag components are presented in a first part. Then, the performance estimated by the aerodynamic module on some reference configurations are compared with both numerical and experimental data, showing a quite good agreement for both Tube and Wing and Blended Wing Body configurations.
