Precooled hydrogen fuelled hypersonic engines offer the capability to achieve Mach 5 terrestrial transport and enable single stage to orbit reusable launch vehicles. This concept is set to revolutionise access to space, potentially delivering a ten-fold cost reduction compared to current launch systems. Key to propulsion efficiency is a unique precooler developed by Reaction Engines. There is very little experience globally in the integration of such devices into hypersonic propulsion systems, and a previous TSB feasibility study highlighted some important potential flow inefficiencies. This project will undertake CFD modelling and experimental measurements to provide understanding of the flow through the precooler installation. It will use this to design, manufacture and test an optimised cowl and centrebody aimed at improving the precooler installation aerodynamics. This study is critical to gain future private investment in this ground-breaking technology, aiding innovation in line with NSTS.

预冷氢燃料高超声速发动机提供了实现5马赫地面运输的能力，并使单级到轨道可重复使用的运载火箭。这一概念将给进入太空的途径带来革命性的变化，与目前的发射系统相比，潜在地将成本降低10倍。推进效率的关键是由反应引擎开发的独特的预冷器。在全球范围内，将这种装置集成到高超声速推进系统中的经验非常少，以前的TSB可行性研究强调了一些重要的潜在流动效率低下的问题。该项目将进行CFD建模和实验测量，以了解预冷器装置中的流动情况。它将利用这一点来设计、制造和测试优化的整流罩和中心体，旨在改善预冷器安装的空气动力学。这项研究对于获得未来对这项突破性技术的私人投资至关重要，有助于与NST保持一致的创新。
