Parameter

3.1.2.5 gas turbine systems

Gas turbine systems are the primary thermal propulsion units of modern aircraft that must be adapted to combust alternative fuels such as hydrogen or sustainable aviation fuel. These adaptations allow for significant direct carbon reductions without fully redesigning the airframe. Challenges in developing these modified systems lie in managing high combustion temperatures, preventing flashback when burning hydrogen, and minimizing nitrogen oxide emissions.
