Purpose – This study investigates NOx emissions from the 50 most used commercial jet aircraft engines. The primary aim is to derive regression models to estimate NOx emissions based on engine parameters. --- Methodology – The analysis begins by determining the 50 most used engine families in passenger aviation, based on the World Airliner Census 2020 and aircraft delivery data from the major commercial aircraft manufacturers. NOx emissions were obtained using the ICAO Engine Emissions Data bank (EEDB). Emissions were analyzed for different flight phases from the ICAO Landing and Take-Off (LTO) Cycle (taxi, take-off, climb, and approach) and for cruise. For the cruise phase NOx emissions were calculated a) with the Boeing Fuel Flow Method 2 (BFFM2) based on LTO NOx and cruise fuel flow and b) with a method developed by the German Aerospace Center (DLR). Non-linear regression analysis was applied to estimate NOx emissions based on one or two selected engine parameters. Separate models were developed for the full dataset and for 13 specific combustor technology subgroups. --- Findings – NOx emissions from aircraft contribute to local air pollution near airports and to global warming at cruise altitude. Legal limits for NOx emissions are defined for the total LTO emissions per thrust as a function of Overall Pressure Ratio (OPR), with stricter standards introduced since 2004. The 50 selected engine families represent around 95% of the global commercial jet fleet. NOx emissions from the BFFM2 and the DLR method agree well (R² = 0.99). The most predictive engine parameters are OPR, thrust and fuel flow, while Bypass Ratio (BPR) has limited influence. Engine design is a trade-off. Low fuel burn requires higher OPR, which increases NOx emissions. Some combustors can reduce NOx but may lead to more soot emissions, causing denser contrails with more global warming potential. Combustor-specific regression significantly improves prediction accuracy. A model incorporating all combustor types yields a coefficient of determination of only R² = 0.398 and a Mean Absolute Percentage Error (MAPE) of only 62.5%. In contrast, combustor-specific models are much better. E.g. a model for the Twin Annular Premixing Swirler (TAPS) II achieves R² = 0.788 and a MAPE of 12.7%. This underlines the necessity of considering combustor technology in NOx estimation. --- Research Limitations – In this study, regression analysis was limited to a maximum number of two input parameters. However, more parameters seem not to lead to a substantially higher accuracy. --- Practical Implications – The study provides equations for three NOx emission cases: total emissions during the LTO cycle, emission index at take-off, and emission index during cruise. For each of these three cases and for each of the 13 investigated combustor technologies, one equation is proposed based on one engine parameter and a second equation based on the best combination of two engine parameters. This leads overall to 78 equations. --- Social Implications – Easy to use equations make NOx emission from passenger jet aircraft more accessible to a wider community of people to discuss the implications of aviation as a means of transport. --- Originality – No other study seems to be available that offers such a simple way to predict NOx emissions form jet engines for aircraft design or aircraft operation while accounting for different combustor technologies.

This dataset focuses on vibration and acoustic signals from a test bench based on the DGEN 380 turbofan, a small engine compared to those typically used in commercial aircraft. It provides a unique opportunity to explore the dynamics of a turbofan engine under different configurations, offering insights into vibroacoustic interactions and the impact of structural elements, such as Outlet Guide Vanes (OGVs), on the engine behavior. The test bench features a planetary gearbox with three planets, where the ring serves as the input, the sun as the output, and the carrier remains fixed. Key characteristic frequencies can be tracked, including the blade passing frequencies (BPF) and shaft-related frequencies for both the low-pressure (LP) and high-pressure (HP) shafts. The instrumentation setup includes three 3-axis accelerometers (A/34-2) positioned along the engine at specific locations, measuring vibration in the x, y, and z axes. The setups also include microphone distributions according to ISO 3746 standards and specific placements around different engine components, such as the rotor and stator. Four measurement configurations were employed, considering both the presence and absence of OGVs. The dataset includes acoustic and vibration signals for each configuration across different operational regimes, including idle, intermediate speeds, and full throttle. This controlled test environment allows for detailed analysis of the interaction between vibration and acoustic phenomena, providing insights that are valuable for diagnosing and improving turbofan engine performance.
