Development of transonic and supersonic CFD modelling and design optimisation techniques for spaceplanes

对于计算流体力学博士来说，这是一个令人兴奋的机会。学生将与令人兴奋和开拓性的英国航空航天公司Reaction Engines Ltd(REL)密切合作，同时获得跨音速CFD和计算优化方法的最新经验。本博士学位将专注于在跨音速飞行方案中开发和应用计算空气动力学优化方法来设计REL的天龙航天飞机。该项目的目标将是开发一种新的基于网格的优化系统，该系统可以与埃文斯博士开发的方法结合使用，该方法可以利用进化算法和“人在回路”优化技术。该项目将探索将复杂的设计约束整合到优化过程中的新方法，以及探索多目标优化的实现。瑞尔的埃文斯博士和空气动力学工程师将提供监督，以确保结果支持正在进行的斯凯伦开发计划。将使用的CFD平台是用于设计空客A380和猎犬陆地速度记录汽车的FLITE3D CFD系统。该项目的最终目标将是让REL更好地了解有翼、可重复使用的运载火箭的最佳几何结构，以及为未来的工作提供可信的跨音速建模能力和优化技术。这是一个影响很大的项目，将在航空航天器的设计中发挥关键作用，这将是全球航空航天能力的一步变化。

This is an exciting opportity for a PhD in Computational Fluid Dynamics. The student will work closely with an exciting and pioneering UK aerospace company, Reaction Engines Ltd (REL) whilst gaining experiencing in the state of the art in transonic CFD and computational optimisation methods. This PhD will focus on the development and application of computational aerodynamic optimisation approaches to the design of REL's Skylon space plane in the transonic flight regime.The aim of the project will be to develop a novel mesh-based optimisation system that can be used in conjunction with methods developed by Dr Evans that can exploit evolutionary algorithms and 'human in the loop' optimisation techniques. The project will explore novel methods for integrating complex design constraints into the optimisation process as well as exploring implementations of multi-objective optimisation. Supervision will be provided by Dr Evans and aerodynamics engineers at REL to ensure that outcomes support the ongoing Skylon development programme. The CFD platform that will be used is the FLITE3D CFD system used for the design of the Airbus A380 and Bloodhound Land Speed Record car. The ultimate goal of the project will be to provide REL with a greater understanding of the optimal geometric configuration of winged, reusable launch vehicles as well as delivery of trusted transonic modelling capabilities and optimisation techniques for future work. This is a high impact project that will play a critical role in the design of aerospace vehicles that will be a step-change in global aerospace capabilities.
