BWB baseline II-E2 UAV structural finite element model and analysis

This paper discusses the process of generating structural finite element model (FEM) and its static analysis to the UiTM´s Blended Wing Body (BWB) Baseline II-E2 Unmanned Aerial Vehicle (UAV). The BWB UAV airframe was designed, and solid model developed using Computer Aided Design software. Aluminum 7075 was used as the main carrying load material. The study was carried out by converting and rebuilding the Computer Aided Design (CAD) model into FEM model by the aid of PATRAN software. A set of static loading was applied onto the model. Finite Element (FE) analysis was performed using the NASTRAN FE software. The result is presented in the form of the stress and displacement distribution.
