In this blog, we heard about conceptual design and optimization in eVTOL.
In order to stay ahead in this emerging industry, startups and original equipment manufacturers (OEMs) must take advantage of new tools and methods to streamline the development process.
Often global conceptual models at full eVTOL vehicle level and detailed models at sub system levels are built in a disconnected manner by different teams, leading to inefficient approaches when a synchronization of all models with the latest design data is required.
To overcome the limitations of a disconnected model build process, we propose a unified workflow that connects structural models at different system levels and enables seamless load transfer between the models while ensuring associativity with parametric design data. In this study, two structural models i.e. a conceptual model at full vehicle level and a detailed wing model are embedded in same design environment on 3DEXPERIENCE platform. The focus of this study is on simulations for the detailed wing model. In a first step, linear buckling analyses are performed on parametric geometry to find the best configuration of the wing structure subject to constraints on the skin buckling load. For final validation a fully nonlinear analysis provides information on the post-buckling behavior up to collapse.
