Rolls-Royce low-emission Combustion System ALECSys Enters Flight Test Phase

Rolls-Royce has successfully entered the final phase of testing it’s ALECSys (Advanced Low Emissions Combustion System) demonstrator engine, this time at altitude. (Earlier post.) The demonstrator took to the skies attached to the Rolls-Royce Boeing 747 Flying Test Bed in Tucson, Arizona.

The test program has included flights up to 40,000 feet as well as a number of engine relights at different conditions, all of which have been successful.The innovative lean-burn combustion system improves the pre-mixing of fuel and air prior to ignition, enabling cleaner combustion of the fuel, which results in lower NOx and particulate emissions.
The ALECSys engine demonstrator has previously completed a comprehensive set of ground tests, including icing, water ingestion, ground operability, emissions and running on 100% Sustainable Aviation Fuel (SAF).
The ability to test ALECSys low-emissions technology in flight will allow the verification of altitude operability performance and provides experience of operating a lean-burn system to maximise maturity ahead of a future entry into service.
ALECSys is part of the UltraFan engine demonstrator program, which offers a 25% fuel saving over the first generation of Trent engines. The ALECSys program is supported by the EU’s Clean Sky program, and in the UK by the Aerospace Technology Institute and Innovate UK.

Under this background, the 10th Annual China Aerospace Propulsion Technology Forum 2022 will be held in December from 8th to 9th in Guiyang city, Guizhou Province, China. The forum will help industry players to understand the current hot spots of aero-engine further, meet new partners and discover new business opportunities.

The forum is dedicated to building a platform for technical exchange, enhancing the interaction between buyers and suppliers, contribute to the prosperity and development of aviation science and technology. You are warmly welcome to attend the forum to have a talk with officers from CAAC, Decision Makers from OEMs, Experts, Manufacturing and MRO Enterprises, Testing and Verifying Suppliers and etc.
