Ammonia-Blended Turboprop Engine Proposed to Reduce Carbon Emissions in Aviation

Strategic Insights

— 1 min read

Amid the growing global urgency to reduce carbon emissions, researchers have proposed an innovative solution to achieve carbon neutrality in aviation by developing an ammonia-blended turboprop engine with a chemical regeneration cycle. Funded by the National Natural Science Foundation of China, China Postdoctoral Science Foundation, and Heilongjiang Provincial Postdoctoral Fund, the study aims to address the challenge of reducing carbon emissions in the aviation industry.

Key Takeaways:

  • The ammonia-blended turboprop engine reduces carbon emissions by 33.97% compared to conventional kerosene turboprop engines.
  • The decomposition of ammonia enhances fuel combustion speed from 1 cm/s to 520 cm/s.
  • The indirect combustion process reduces exergy loss by 5.2%, contributing to improving the overall energy utilization level of the engine.
  • The research proposes a systematic theoretical framework and technical implementation pathway for future advancements in green aviation propulsion.
  • The study was peer-reviewed and published in the journal Energy, with funding provided by the National Natural Science Foundation of China.
  • The research team, led by Daren Yu from the Harbin Institute of Technology, includes Cong Wang, Jiang Qin, Jiwei Fang, Xinyan Xiu, Lei Lang, Taiqiu Liu, and Jie Xu.

Statistics:

  • 33.97% reduction in carbon emissions compared to conventional kerosene turboprop engines.
  • 520 cm/s enhancement in fuel combustion speed.
  • 5.2% reduction in exergy loss through the indirect combustion process.
  • 2025: the year the research was conducted and published.
  • 334: the volume number of the journal Energy where the research was published.
