NUMERICAL STUDY ON THE FLUID-STRUCTURE COUPLING BEHAVIOUR OF CASCADE-TYPE THRUST REVERSER UNITS FOR WEIGHT OPTIMISATION

摘要

Multidisciplinary optimisation is a key for improving aeronautic products. A Fluid-Structure Interaction (FSI) process composed of multidisciplinary numerical tools was developed to allow components to be designed for minimum weight whilst meeting aero-structural functionality. Key aspects such as geometry simplification and interfacing aerodynamic (CFD) and structural (FEM) analysis were identified and incorporated. The process was applied to a parametric study on a generic cascade TRU. The results showed that the process can successfully guide component design towards low weight whilst preserving aero-structural functionality.
