Purpose and goal: The purpose of the multidisciplinary project is to develop industry adapted tools and best-practice guidelines to computationally couple fluid and structure dynamics (aeroelasticity) as well as aeroacoustics with the aim to introduce this multidisciplinary technique in an industrial aeronautical context, contribute with scientific publications and actively contribute to knowledge dissemination within the field between industry, academia and institute. Expected results and effects: The project is expected to result in a computational capability that makes it possible to predict external noise and cabin noise due to cavities and non-aerodynamic axisymmetric bodies at transonic speed, aeroelastic deformations in cavities at transonic speed as well as external noise and cabin noise induced by aeroelastic effects. Effects due to the project are e.g. an improved industrial multidisciplinary computational capability which can be used in the development of future more environmentally friendly as well as resource and cost efficient civil and military aircraft. Approach and implementation: The project will start from existing research front methods for fluid-structure interaction and aeroacoustics. The project will improve the coupling between the disciplines and establish a computational framework in order to ensure accuracy and efficiency needed for industrial aeronautical applications. The project will study 1) fluid-structure interaction and aeroacoustic phenomena in cavity applications and 2) aeroacoustic phenomenon around non-aerodynamic axisymmetric bodies.
