Recent Advances in High-Fidelity Multidisciplinary Adjoint-Based Optimization with the NSU3D Flow Solver Framework

摘要

This paper describes the various components in the development of a coupled multidisciplinary optimization capability for rotorcraft problems. The underlying approach is based on the use of a time dependent discrete adjoint capability that is extended to multiple disciplines, including aerodynamic, structural dynamic and acoustic disciplines. Examples of optimizations for rigid and flexible rotors are given based on aerodynamic performance and aeroacoustic signature objectives. The extension of the structural model to a full geometrically non-linear brick and shell finite-element model is also described and preliminary results are shown.
