Rolls Runs New Lean-burn Combustor
Rolls is focussing on refining next-gen lean-burn combustor as it eyes closer engine-airframe integration, and electrification.

Rolls-Royce (Stand N23) is planning further flight-, ground-, and rig-testing of its advanced “lean-burn” combustor system (ALECSys) demonstrator that was first run last month, according to R-R Civil Aerospace future programs chief engineer, Phil Curnock. The technology, which introduces a new lean-burn concept to a more traditional engine design, has been demonstrated on an Advance 3 rig and ground-tested on a modified Trent 1000 engine.
