EFFICIENT APPLICATION OF CFD AEROELASTIC METHODS USING COMMERCIAL SOFTWARE

Aeroelastic analyses in transonic regime require the adoption of accurate aerodynamics physical models, such as Euler or Navier-Stokes equations. To move the application of these type of analyses from a pure academical environment to an industrial one, it is necessary to show that the technology is mature enough to be implemented without using specialized pieces of software. This paper presents a numerical procedure defined to solve Fluid-Structure Interactions (FSI) for aeroelastic problems using partitioned procedures based on the adoption of “black-box” commercial software for the solution of each field. A special attention is given to the efficiency of the procedure, keeping in mind the high number of analyses that have to be run during the development of a new aircraft.
