Rolls-Royce expands testing of low emission tech 

Rolls-Royce has started its latest phase of testing on its low-emissions technology for its next generation of engines. An ALECSys (Advanced Low Emissions Combustion System) demonstrator engine – with technology that features in both the Advance3 and UltraFan programmes – has resumed ground test runs in Derby UK. Reducing emissions from gas turbines is part of the wider Rolls-Royce sustainability strategy, which also involves support for the increased use of sustainable aviation fuels (SAF) and intensive research into disruptive propulsion architectures and technologies. The lean-burn combustion system improves the pre-mixing of fuel and air prior to ignition – delivering a
