The complexity of Very High Bypass Ratio (VHBR) lean burn combustion systems requires careful fuel control and optimised staging to minimise non-volatile particulate matter (nvPM) emissions. Fuel flow variation across injectors will impact the temperature distribution through the turbine and thus influences rates of nvPM formation and consumption. Through Clean Sky 2, Rolls-Royce are developing technologies required for VHBR engines. CIDAR (Combustion species Imaging Diagnostics for Aero-Engine Research) supports this initiative.
