Rolls-Royce has run a demonstrator engine specifically devoted to the optimisation of a new lean-burn and low-emissions combustion system for the first time. This system is being designed for future jet engine programmes.
The ALECSys (Advanced Low Emissions Combustion System) demonstrator successfully ran for the first time on a testbed in Derby, UK. Technology from the system features in both the Advance3 and the UltraFan demonstrator programmes. The lean-burn system improves the pre-mixing of fuel and air prior to ignition – delivering a more complete combustion of the fuel and, as a result, lower NOx and particulate emissions, both of which are increasingly important to airline customers in terms of operating economics and environmental performance.
The lean-burn system will play an important part in delivering the IntelligentEngine, Rolls-Royce’s vision for the future, as it builds on pioneering technology and digital capabilities to deliver important benefits for customers.
