This Bachelors Thesis is focused on studying and analyzing the Single Engine Taxi-out (SETO) procedure for A320 and A319 aircraft in the current aviation landscape, where reducing carbon footprint and cost savings have become priorities for airlines. The procedure consists of the use of a single engine to perform the taxi-out, which can result in a significant reduction in fuel consumption and greenhouse gas emissions. The main objective of the research is to evaluate the feasibility of SETO in terms of fuel savings, considering variables such as aircraft type, taxiing distance, airport size, aircraft weight, among others. To achieve this, pre-takeoff cockpit procedures have been examined and a comprehensive analysis has been conducted using data collected from real flights extracted from a renowned airline within the European framework. The methodology used consisted of an evaluation of the procedures carried out by the flight crew in the cockpit before and during SETO. This allowed to identify critical points of the maneuver and the developing of a comprehensive guide of considerations for pilots to determine whether the SETO maneuver meets the necessary safety standards and is suitable to conduct. Additionally, a linear regression analysis has been conducted to investigate the relationship between the application of SETO maneuver and fuel consumption during the taxi-out phase. In conclusion, the results of the data analysis have revealed a significant relationship between the application of SETO and the reduction of fuel consumption during the taxi-out phase. This supports the assertion that this procedure leads to both emissions and cost reductions. Furthermore, it has been found that the viability of SETO is independent of the ground distance covered once a defined threshold has been exceeded.

Purpose - This thesis presents a comparison of aircraft design concepts to identify the superior propulsion system model among turbo-hydraulic, turbo-electric and classic jet propulsion with respect to Direct Operating Costs (DOC), environmental impact and fuel burn. --- Approach - A simple aircraft model was designed based on the Top-Level Aircraft Requirements of the Airbus A320 passenger aircraft, and novel engine concepts were integrated to establish new models. Numerous types of propulsion system configurations were created by varying the type of gas turbine engine and number of propulsors. --- Findings - After an elaborate comparison of the aforementioned concepts, the all turbo-hydraulic propulsion system is found to be superior to the all turbo-electric propulsion system. A new propulsion system concept was developed by combining the thrust of a turbofan engine and utilizing the power produced by the turbo-hydraulic propulsion system that is delivered via propellers. The new partial turbo-hydraulic propulsion concept in which 20% of the total cruise power is coming from the (hydraulic driven) propellers is even more efficient than an all turbo-hydraulic concept in terms of DOC, environmental impact and fuel burn. --- Research Limitations - The aircraft were modelled with a spreadsheet based on handbook methods and relevant statistics. The investigation was done only for one type of reference aircraft and one route. A detailed analysis with a greater number of reference aircraft and types of routes could lead to other results. --- Practical Implications - With the provided spreadsheet, the DOC and environmental impact can be approximated for any commercial reference aircraft combined with the aforementioned propulsion system concepts. --- Social Implications - Based on the results of this thesis, the public will be able to discuss the demerits of otherwise highly lauded electric propulsion concepts. --- Value - To evaluate the viability of the hydraulic propu

The aviation sector is growing every year with a steady pace of 5%. With this growth, the greenhouse emissions can only rise in the future until new innovative aircraft are designed such as electrical aircraft. An interim solution is to switch the fuel from kerosene to Liquefied Natural Gas (LNG). LNG is much cleaner for the environment, cheaper and more abundant. This study looks into retrofitting conventional aircraft to work on LNG, in this case an Airbus A320 since it the most used airplane in the commercial aviation. A cryogenic tank to store the LNG, was designed and incorporated into the cargo bay replacing some of the cargo. The two aircraft were generated and compared using a preliminary design tool, the Initiator. The LNG aircraft achieved a significant reduction in CO2 and NOx , 24% and 69% respectively. In addition to a potential saving of 17% in direct operating cost., Aerospace Engineering

Structural improvements in aircraft design, seeking to improve energy efficiency, can significantly reduce greenhouse gas emissions (GHG) by reducing reduced fuel consumption. This research reviews improvements with the introduction of a structural component known as "winglet;" these are positioned at the top of the aircraft wing, and increased Airbus Group A320 sales. Data used are taken from air traffic in Spain for the 2010–2014 period with projections being made for 2020. The results show that winglets reduce CO2 equivalent emissions associated with Spain's air transport for the 2015–2020 period between 66.29 and 59.56 Gg. depending on the scenario considered in 2020.
