项目摘要

Research conducted as the primary focus of this PhD will determine strategies to radically reduce the climate impact of aviation, in the interim before all-electric aircraft become technologically and economically feasible. This will include development of a new tool, or extensions to existing tools, in order to accurately and comprehensively quantify the climate impact of flight. This will then be used to quantify the relative merits of each type of novel aircraft technology, and exploration of the potential for synergy between two or more of these approaches to reduce the overall environmental impact of aircraft. For example: General use of hybrid electric aircraft to eliminate a proportion of the direct emissions on an aircraft powered by sustainable aviation fuel. Targeted implementation of hybrid electric propulsion in particularly climate-sensitive regions of the atmosphere, where the release of emissions has a much more prominent influence on the surrounding environment. Use of hopping flight (which, counterintuitively, leads to lower fuel burn on longer routes ), or Air-to-Air refueling to allow smaller, more efficient aircraft to travel longer distances. An extensive review of promising mitigation strategies will be carried out using the quantification tool developed. Once a primary mitigation strategy has been determined, this will be more deeply developed, ideally in collaboration with relevant industrial partners, in order to determine a route to implementation and a definitive environmental and economic impact statement.

作为本博士论文的主要重点进行的研究将确定从根本上减少航空对气候影响的战略，在全电动飞机在技术和经济上可行之前的过渡时期。这将包括开发一个新的工具，或扩展现有的工具，以便准确和全面地量化飞行对气候的影响。这将被用来量化每种新型飞机技术的相对优点，并探索其中两种或两种以上方法之间协同作用的潜力，以减少飞机对环境的总体影响。例如：普遍使用混合动力飞机，以消除以可持续航空燃料为动力的飞机的部分直接排放。有针对性地在大气层气候敏感地区实施混合动力电力推进，这些地区的排放对周围环境的影响要突出得多。使用跳跃飞行(与直觉相反，这导致较长航线的燃油消耗较低)，或空对空加油，允许更小、更高效的飞机进行更长距离的飞行。将使用开发的量化工具对有希望的缓解战略进行广泛审查。一旦确定了主要的缓解战略，将更深入地制定这一战略，最好是与相关的工业合作伙伴合作，以便确定实施路线和明确的环境和经济影响声明。
