Engineering giant Rolls-Royce has announced it has resumed testing on a revolutionary low-emissions technology for its next generation of engines.
The firm has revealed that its ALECSys (Advanced Low Emissions Combustion System) demonstrator engine, with technology that features in both the Advance3 and UltraFan engine programmes - has restarted ground test runs at its civil aerospace site in Derby.
As part of its sustainability strategy, Rolls-Royce is working to reduce emissions produced by its future engines.

It is also looking to develop technology that can support the increased use of sustainable aviation fuels.
Its ALECSys technology is a lean-burn combustion system, designed to improve the pre-mixing of fuel and air prior to ignition.
According to Rolls-Royce, this will deliver a more complete combustion of the fuel, resulting in lower emissions.
The development of the system is being supported by the EU via Clean Sky, and in the 海角视频 by the Aerospace Technology Institute and Innovate 海角视频.
The first series of tests began in 2018 and this latest phase will focus on validating emissions performance, engine control system software and functional performance.

“We’ve been excited by our results so far and we are now going to push on and see what more ALECSys can deliver.”
The tests commence as Rolls-Royce starts to build the first parts for the UltraFan demonstrator, which will start ground tests next year.
According to Rolls-Royce, the UltraFan will offer a 25%fuel saving compared to its first generation of Trent engine, making it an attractive proposition to customers.
