Tailoring aircraft surface textures to minimise drag
Grant number: DP170102595 | Funding period: 2017 - 2019
This project aims to optimise textured surfaces for reducing fluid dynamic drag. The project builds on recent breakthroughs in drag-evaluation methods and the associated physics. Reducing drag is valuable because it raises the costs of operating aircraft and ships. The intended outcomes are optimal drag-reducing surface textures, a further physical understanding of drag-reduction mechanisms and an improved modelling capability of drag-reducing surfaces. This project is expected to benefit the transport and logistics industries in Australia and globally.
