Project description
High-tech, non-invasive imaging supports aeroengine particulate and CO2 emissions reduction
The European aerospace industry is accelerating research and development aimed at lowering the environmental impact of aviation. Reducing the particulate and CO2 content of aeroengine exhaust is a key focus. The EU-funded CIDAR project will develop two non-invasive imaging technologies to address this goal, with a focus on future highly efficient very-high-bypass-ratio engines. Calibration-free fibre laser absorption spectroscopy will enable non-intrusive planar tomographic measurement of CO2. Laser-induced incandescence will allow non-volatile particulate matter measurements. CIDAR will test, optimise and validate the technologies, using large civil turbofan engines. These will allow faster and more accurate detection without affecting engine performance, cutting the engine core optimisation time and cost.
Objective
The CIDAR project is the result of a Consortium formed by Academic Parties (Manchester, Strathclyde and Edinburgh Universities), a Research and Development Organization (INTA) and private companies (DAS and OptoSci). Therefore, CIDAR builds upon the expertise of the UK's and Spain’s world-leading groups in fibre-lasers, laser based gas and particulate detection, opto-electronics, and chemical species tomography (CST), allied to its industrial strengths in aero-engine manufacture and aviation fuel technology.
The CIDAR project aims to establish a world-leading capability in the non-intrusive measurement and 2D imaging of nvPM/soot and CO2 concentrations in aero-engine exhaust. Non-intrusive planar tomographic measurement of CO2 will be based on calibration-free Fibre-Laser Absorption Spectroscopy and soot measurements will be based on laser-induced incandescence (LII).
Validation of both imaging technologies will be carried out at the INTA Turbojet Test Centre using large civil turbofan engines, providing data analysis and measurement uncertainty of the current state of the art measurement systems.
The measurement system will then be developed to a maturity level of TRL6 with a clearly identified route to commercialisation.
