Status of the elsA Software for Flow Simulation and Multi-Disciplinary Applications

Abstract

This paper gives an overview of the elsA Onera software for complex external and internal flow simulations and multidisciplinary app lications. The objectives of the elsA software co-operative project are presented. The pa per outlines capabilities of the software. A first set of recent applications illustrates some important features: fundamental applications for RSM turbulence modeling, wing/fuselage and tilt-rotor configurations for advanced multi-block techniques, transport aircraft for fluid/structure coupling, powerplant integration for calculation of sensitivities, wing buffet prediction for Detached Eddy Simulation. Then, a second set of applications show s the diversity of configurations which are today addressed by elsA : optimisation of a supersonic transport aircraft, high lift aircraft configuration, helicopter rotor-fuselage i nteraction, compressor and turbine stages, heat transfer analysis in a nozzle guide vane, spac e vehicle configuration. The paper finally outlines the perspectives of development of the elsA software.
