This report is a part of the 2017 deliverable for FoT project Modelleringsteknik och Prestandaanalys. The report describes briefly the activities undertaken in the work package concerning Miljöbedömningar och livscykelkostnader. Since the work is progressing at its initial stage, the report should be viewed as a brief status report and an outline for future investigation. In 2017 the activities have mainly been devoted to an exploration of the predictive methods for aircraft noise emissions with a particular focus on sonic boom for supersonic air vehicles. This includes literature studies, a revisit of FOIs current computational methods based on Computational Fluid Dynamics (CFD) and Computational Aero-Acoustics (CAA), as well as on computations of supersonic flows in the presence of shock waves and sonic booms. The further work will be undertaken based on existing computer codes, including Bangprognos from the customer, with necessary improvements. The report starts with some general background and aspects on noise from air vehicles and sonic booms based on an initial open literature survey. It continues with a description on the current FOI in-house capabilities using hybrid CFD/CAA methods, as well as a preliminary analysis made on a generic platform at a supersonic speed with the focus on the source output and its possible use for future noise control and optimization. The report is concluded with an outline of future work plan.
