The main drivers that will shape the future of aviation will be contributions to climate forcing due to carbon dioxide emissions and contrails formation. Currently, there seems to be no viable prime mover that will replace the gas turbine as the preferred engine for the medium to long range commercial aircraft. It is expected that for the near future these engines will be fueled by liquid hydrocarbons produced from sustainable sources. Today, civil aviation contributes about 3-5% of the anthropogenic greenhouse gas emissions due to conventional aviation fuel use. Unless the impediments to replacing current aviation fuels by sustainable ones are removed, the negative impacts of aviation on the earth's climate will continue to intensify. Sustainable aviation fuels (SAF) are defined as renewable or waste-derived aviation fuels that meet sustainability criteria. Technical analysis done at International Civil Aviation Organization shows that SAF has the greatest potential to reduce carbon dioxide emissions from International Aviation. However, there exist several knowledge gaps and barriers to adopting new fuels; some are technical and scientific, and some others are related to sustainability and logistics. The proposed project aims to contribute to the advancement of knowledge in (a) emissions characteristics of seven SAF, specified by the aviation industry organizations and produced by specified processes, under engine-relevant combustion conditions, and (b) production and combustion/emissions characteristics of a new class of potential aviation fuels Polyoxymethylene Dimethyl Ethers (PODE) and its blends. Our research efforts will include parallel experiments and numerical simulations. The deliverables of this research program will address the technical and scientific knowledge gaps in using new fuels in aviation by providing detailed information about the emissions characteristics under engine-relevant conditions. Results will help the Canadian gas turbine engine manufacturers to evaluate the impacts of engine exhaust on the environment, and facilitate the decision-making and strategies for the potential of future aviation fuels for a low-carbon path to zero-emission aviation.

塑造航空的未来的主要驱动因素将是由于二氧化碳排放和围栏形成而导致气候强迫的贡献。目前，似乎没有可行的主要推动者可以取代燃气轮机作为中型至远程商用飞机的首选发动机。预计在不久的将来，这些发动机将由可持续来源产生的液体碳氢化合物推动。如今，由于常规航空燃料的使用，民航占人为温室气体排放的约3-5％。除非除去可持续发展燃料的障碍替代当前航空燃料，否则航空对地球气候的负面影响将继续加剧。可持续航空燃料（SAF）被定义为符合可持续性标准的可再生或废物衍生的航空燃料。国际民航组织进行的技术分析表明，SAF具有减少国际航空中二氧化碳排放的最大潜力。但是，采用新燃料存在几个知识差距和障碍。有些是技术和科学的，而另一些则与可持续性和后勤有关。拟议的项目旨在为（a）七个SAF的知识发展做出贡献，该特征由航空业组织指定，并由特定过程，在相关发动机相关的燃烧条件下以及（b）潜在的潜在航空燃料的生产和燃烧/排放特征（b）新型潜在的燃料燃料的生产/燃烧/排放特性。我们的研究工作将包括并行实验和数值模拟。该研究计划的可交付成果将通过提供有关与发动机相关的条件下的排放特性的详细信息，以解决使用新燃料的技术和科学知识差距。结果将有助于加拿大燃气轮机发动机制造商评估发动机排气对环境的影响，并促进决策和策略，以实现未来航空燃料的潜力，以实现低碳通向零发射航空的路径。
