In a bid to simultaneously reduce both fuel consumption and all pollutant emissions–goals that are often at odds–French aerospace research center Onera and engine manufacturer Snecma are working on the next generation of low-NOx combustors
Exhaust gas recirculation
As part of its Green Rotorcraft initiative, the Clean Sky public-private partnership for aeronautical research in Europe has issued its second call for proposals seeking such improvements as diesel engines, electric tail- rotor drive and waste heat conversion to electricity, all of which are expected to contribute to targeted drastic cuts in noise, CO2 and NOx emissions.

Rolls-Royce is now exploring future engine technologies that, although challenging, are key to the ambitious Advisory Council for Aerospace Research in Europe (ACARE) goals for 2020 in terms of nitrous oxides (NOx) and carbon dioxide (CO2) emission cutting and noise reduction. These technologies range from heat exchangers to shape memory alloys and magnetic bearings.
