The social responsibility for the environment, in conjunction with the threat of more stringent emissions regulations requirements, initiated a comprehensive NOx-emissions reduction programme in BMW Rolls-Royce. The achievements of the first step for NOx-emissions reduction by optimisation of the single annular combustor stoichiometry and mixing are presented. The combustor development programme is described, and rig and engine test results are compared. The NOx-certification levels achieved with the BR 710 single annular low NOx-combustor are down to 55 % of the actual ICAO limit.
