“…Moreover, these aviation emissions have started to be debated in global extent since it is observed that harmful gaseous lead to health concerns of people that especially live to vicinity of airports. To decrease fuel consumption, thereby harmful effects from aircraft, there are a number of attempts such as using renewable energy, applying novelties to the engine and airframe, higher efficiently air traffic management and new binding deal on emissions such as CORSIA regulated by ICAO [ 9 ]. More green environment and less fuel consumption by integrating different engineering areas have been hot topics of aviation sector.…”

As a kind of gas turbine engines, turbofan engines have powered a number of aero-vehicles in aviation sector. The necessity of turbofan with higher energy efficiency has been greatly drawn attention since these are operating dependent to fossil fuels. In this study, energy and emission metrics of fifty-one mixed flow turbofan engines (MFTE) with different bypass ratio, overall pressure ratio and fuel flow are modeled with multi-regression (MR) method. The obtained models are subjected to metaheuristic approaches involving genetic algorithm (GA) and simulated annealing (SA) so as to decrease error of the models. According to MR findings, rated thrust of MFTEs is estimated with 1.4877 of minimum square error (MSE) whereas GA and SA make it lower as 1.3404 and 1.2524, respectively. On the other hand, NO x emission index of MFTEs is predicted with relatively low coefficient of determination (R 2 ) as 0.8620. However, its accuracy is enhanced to 0.8633 (with GA) and 0.8655 (with SA). Finally, exergy efficiency of MFTEs is estimated the highest model correctness with GA. Namely, R 2 of the model is computed as 0.9280 with GA and 0.9277 with SA. Without applying these methods, its R 2 is obtained as 0.9263 with MR. When considering these outcomes, thanks to modeling and optimization methods, prediction of performance and emission indexes of mixed flow turbofan engines could be performed with lower error values. It is thought that the study helps in prediction of environmental effect regarding turbofan engines that are utilized at busy airports.

“…Flight phases consist of two main parts. The first part is called the LTO stage (taxi-out, take-off, climb-out, final approach, landing, and taxi-in), and the second part is called the CCD stage (climb, cruise, and descent) [22]. While aircraft-induced emissions at the CCD stage cause global air pollution, the LTO stage has a severe impact on local air quality [23].…”

In this study, a comparison in terms of environmental impact is carried out between regional jet and narrow-body passenger aircraft with different Maximum Take-Off Weights (MTOW) and seating capacities considering the fuel burn and emissions. The flight trajectory is selected from Erzincan Yıldırım Akbulut Airport to Ankara Esenboğa Airport and that trajectory is a frequently performed domestic flight between Erzincan and Ankara. Integrated Aircraft Noise and Emissions Modelling Platform (IMPACT) developed by EUROCONTROL is used for the calculation of fuel burn, CO2, H2O, and other gas emissions (NOx, SOx, CO, HC, soot, and other trace compounds) for the per phase of flight. These emissions have an impact on human health, air quality, and the ecosystem, and cause air pollution, climate change, and global warming worldwide. Commercial air-transport-based simulations are created for regional jet and narrow-body passenger aircraft. According to the results, flying with regional jets which have lower MTOW from/to airports such as Erzincan Yıldırım Akbulut Airport, where the passenger density per aircraft is low, provides advantages in terms of fuel burn and emissions. It is expected that this study will serve as a guide for airline operators for fleet selection based on fuel burn and emission parameters.
