In this PhD project the appropriateness of a range of different geometric modelling approaches (e.g. digital geometry, level sets) will be evaluated for this application, along with tests on the different methods of parametrisation that can be applied to each.
We are seeking an enthusiastic person to join the Biohaviour (biohaviour.com) team. The airplane of the future will look and feel very different to that which we are accustomed to today. To support our targets of net zero emissions in 2050 airframes will need to be very light and still cost effective when formed into different shapes. The biohaviour team is exploring new structural geometries and representations that have an organic look and feel, and we are building the tools to automatically create these geometries. The challenge to be addressed in this project is that our manufacturing capability significantly affects the resulting shape, form and material of the configuration and current design methods cannot deal with this. New design methods, CAD tools and algorithms to link with manufacturing will be created and evaluated.
Biohaviour is a bioinspired integrated design and manufacturing system created and developed in QUB. It aims to observe the rules nature uses when designing the world around us, and to capture these in a system where they can be applied to engineering design problems. It is envisaged that by doing so it will be possible to design and manufacture innovative products, free from the constraints imposed on the designs of today by existing design processes.
This PhD will play an important role in the overall project, determining how best to create complex representations of airframe structures. This will involve assessing the different potential modelling methods and to select the most promising approach to construct a real fuselage and wing structure. The second step will be to identify how the geometric description can be integrated with the advanced manufacturing approaches which Biohaviour aims to exploit (e.g. 3D printing).
In this PhD project the appropriateness of a range of different geometric modelling approaches (e.g. digital geometry, level sets) will be evaluated for this application, along with tests on the different methods of parametrisation that can be applied to each. The most appropriate approach will be implemented in a prototype framework where it will be controlled via the bioinspired rules being researched by other members of the team.
Aims and Objectives:
The aim is to determine the most effective design approach for Biohaviour applications in airframe structures and to provide a useable prototype capability to the project.
The objectives are to:
– Identify the different modelling approaches that are available and suited to generative design of airframes.
– Identify the different parameterisation strategies that can be used with each geometric modelling approach
– Evaluate the different geometric modelling approaches in terms of their ability to be adapted as part of a bioinspired design system
– Evaluate the different geometric modelling approaches in terms of their ability to be manufactured using innovative manufacturing approaches
– Prepare a prototype geometric modelling environment for use in biohaviour
