School of Engineering Department of Mechanical and Aerospace Engineering 178 Aircraft Design and Air Transportation Operations: How do they Affect Each Other? Supervisor: LIEM Rhea Patricia / MAE Student: CHAVANACHINDA Phisitchai / MEGBM Course: UROP1100, Fall With the rising demand for air travel, airports around the world find themselves becoming increasingly busy. The traffic congestion and high demand has propelled airlines to explore the use of larger airliners. This paper aims to analyze different ranges of flights and their respective fuel efficiencies, to examine the correlation between payload and efficiency, and to identify the most suitable scenarios for long range aircraft, specifically the B777-300ER. The study helps develop a deeper understanding of the linkage between aircraft design and air transportation operations. The results show that short range flights have higher variance and fluctuations, affecting the accuracy of fuel consumption predictions. Moreover, the results illustrate that the most efficient route distance for long haul aircraft is the medium range, contradicting presumptions about long range aircraft while substantiating the rationale behind utilizing large aircraft on shorter routes. Aircraft Design and Air Transportation Operations: How do they Affect Each Other? Supervisor: LIEM Rhea Patricia / MAE Student: SWAMINATHAN Srivatsav / AE Course: UROP1100, Fall UROP2100, Spring With the rising demand for air travel, airports around the world find themselves becoming increasingly busy. The high passenger demand across different flight routes have incentivised certain airlines to consider using long-range aircrafts such as the Boeing 777-300ER for all variants of flight routes. This paper aims to analyse the fuel burn-offs of the Boeing 777-300ER across different flight routes considering the distance travelled and net flight time. The study helps in developing a deeper understanding of the linkage between aircraft design and air transportation operations. The results show that short-range flight routes have a greater divergence of fuel burn-offs primarily due to the high payload variations across a relatively smaller distance. Furthermore, the results also depict the existence of a critical passenger payload at which the aircraft performs the most optimally. Aircraft Design and Air Transportation Operations: How do they Affect Each Other? Supervisor: LIEM Rhea Patricia / MAE Student: YIU Kwan Ho / AE Course: UROP1100, Fall Conditions in Top Level Requirement is considered as the most efficient way in aircraft operation. However, it is hard to operate aircraft only in such specific conditions. To optimize fuel efficiency, the optimum operation pattern of the aircraft needs to be found. Taking B777-300ER as an example, the longer flight distance, longer flight time and higher payload boost the fuel efficiency. Attaining these conditions, the aircraft tends to operate more fuel efficiently.
