This project around distributed electric propulsion aims to build an aerodynamic understanding of the optimal configurations for distributed electric propulsion. Distributed electric propulsion involves placing small electrically driven propellers along the span of a wing and at the wing tip to improve aerodynamic efficiency. A combination of experiments and computational fluid dynamics will be used to determine the physical mechanism behind drag reduction in wing-tip propellers, and the way in which this is affected by the presence of leading-edge propellers. This will allow the design of an optimised full-wing geometry with increased lift and reduced drag to improve fuel burn. The main application for this is larger transport aircraft that cannot currently be electrified due to the limitations of current battery electric technologies.

这个围绕分布式电力推进的项目旨在建立对分布式电力推进的最佳配置的空气动力学理解。分布式电力推进涉及沿机翼翼展和翼尖放置小型电力驱动螺旋桨，以提高空气动力效率。将结合实验和计算流体动力学来确定翼尖螺旋桨减阻背后的物理机制，以及前缘螺旋桨的存在对减阻的影响方式。这将允许设计优化的全翼几何形状，增加升力并减少阻力，以改善燃油燃烧。其主要应用是大型运输机，由于当前电池电动技术的限制，目前无法实现电动化。
