| Description | 1. A validated instrumentation system and measurement procedure for determining path integrated chemical species (CO2 and NO) concentration and temperature along a single laser beam path across the exhaust plume of a gas turbine (aero) engine. 2. Construction, demonstration and validation, using phantoms, of a 126 beam tomographic system [each as in 1. above] to realise transverse (cross-section) images of chemical species concentration (CO2) in gas flows. |
| Exploitation Route | Research ongoing with the award of the Programme Grant, LITECS (Laser Imaging of Turbine Engine Combustion species), started on September 1st 2020 - see new grant in portfolio. LITECS involves six University research partners and five industry partners including Rolls-Royce and Siemens as end users of the technology for gas turbine engine research and diagnostics. |

| Description | They have been used in a new H2020 Cleansky 2 Project to take the research findings from FLITES to Technology Readiness level 6 (TRL6) for further research and testing of Gas Turbine engines. With support from Rolls-Royce and the above EU project, INTA (Madrid) has established a test-cell facility for the routine testing and emissions monitoring of large commercial aero-engines. The findings are also being used in the now awarded EPSRC Programme grant, LITECS (Laser imaging of turbine engine combustion species), started on September 1st 2020. LITECS involves six university research partners and five industry partners including Rolls-Royce and Siemens as end users of the technology for gas turbine engine research and diagnostics. The vision is to significantly advance the understanding of gas turbine engine combustion and emissions generation processes with a view to developing strategies to achieve emissions reduction. Rolls-Royce has made provision for the implementation of the enabling measurement technologies its new state-of-the-art Test bed 80 facility at Derby, which ran its first engine in January 2021. This is the largest and smartest indoor aerospace test bed in the world. |

| Title | Accurate Recovery of Absorption Line-Shapes Corrected for Laser Modulation Characteristics |
| Description | Data corresponds to the contents of this paper. The paper describes novel methods for recovery of absorption line-shapes using fist harmonic phase sensitive detection techniques.The effect of laser modulation parameters on the recovery of absolute absorption line-shapes using the phasor decomposition method(PDM) is discussed. The theory of laser modulation is discussed from the perspective of wavelength modulation spectroscopy. The paper also demonstrates how the PDM approach can be improved by removing the need to pre-set the orientation of the lock-in axis, making it more suitable for field applications. |
