Aviation's impact on the environment - quantifying the global impact of aviation and proposing a mitigation strategy to drasti

在全电动飞机在技术上和经济上变得可行之前，作为本博士学位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。这将包括开发一种新工具，或对现有工具进行扩展，以便准确和全面地量化飞行对气候的影响。然后，这将用于量化每种新型飞机技术的相对优点，并探索两种或多种方法之间的协同作用潜力，以减少飞机对整体环境的影响。例如：普遍使用混合动力飞机，以消除由可持续航空燃料驱动的飞机的一部分直接排放。在气候特别敏感的大气区域有针对性地实施混合动力推进，在那里排放的排放物对周围环境的影响要突出得多。使用跳跃飞行（这与直觉相反，可以在较长的航线上降低燃油消耗），或空对空加油，使更小、更高效的飞机能够飞行更远的距离。将利用所开发的量化工具对有希望的缓解战略进行广泛审查。一旦确定了主要缓解战略，将更深入地制定这一战略，最好是与相关工业伙伴合作，以便确定执行路线和明确的环境和经济影响说明。

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.
