Ammonia combustion hybrid air propulsion system

Name

Shigeru Obayashi, Institute of Fluid Science, Professor

Outline of Research

The ” Ammonia combustion hybrid air propulsion system” project is a joint research effort with Hiroshima University and Mitsubishi Heavy Industries Aero Engines, Ltd., exploring the concept of applying carbon-free ammonia combustion to aircraft propulsion systems.

Research Purpose

1. Conceptual Study of Ammonia Hybrid Aircraft
Investigate the carbon-free hybridization of regional aircraft through conceptual studies, assuming that the technology will expand from small to large aircraft.
2. Research and Development of Ammonia Hybrid Propulsion System
Develop simulation technology for detailed performance evaluation of the propulsion system. Conduct conceptual design of an ammonia-fueled gas turbine combustor for aviation use.
3. Fundamental Research on Aviation Ammonia Combustion
Conduct a detailed investigation of combustion characteristics inside a swirling flow combustor using laser measurements. Measure ammonia ignition delay time and analyze chemical species using a reaction tube. These experiments will help clarify the fundamental characteristics of ammonia combustion and provide a basis for the above simulation technology.

Expected Effect

The International Civil Aviation Organization (ICAO) aims to achieve carbon neutrality in the aviation sector by 2050. The successful implementation of this research in society will significantly contribute to achieving this goal.

Achievements

Selected for the NEDO Feasibility Study Program, “Ammonia combustion hybrid air propulsion system” (FY2024).
