Description
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. Extractive sampling systems are the current standard method for measuring exhaust gas and fine particle emissions from various types of aircraft engines under actual operating conditions. Emerging non-intrusive approaches to gas and particulate measurement offer alternatives to extractive methods, with some significant advantages (no impact on engine performance and no hardware installed in engine exhaust, bypass or entrained flows)
