“…Using the data in Table 1 and Eqs. (11), (12), (14) and (15), energy and exergy loss rates are calculated for main components of the CFBG system and given in Table 2. As can be seen in Table 2, while the most energy losses belong to the gasifier and PSA equipments as 22.45 and 10.51 MW, respectively, the most exergy losses are due to the gasifier, combustion chamber and PSA components with 47.95, 15.36 and 13.14 MW, respectively.…”

“…The cost coefficient of fuel, , is the key consideration of this study. As the aircraft model under study is A320-200s, which has turbofan engines, the important relationship of altitude, Mach number and velocity of a turbofan is accounted for (Roth and Mavris, 2001;Turgut et al, 2009…”

We studied a methodology for flight trajectory optimization, and also the workloads of air traffic control officers (ATCOs). Case studies were conducted through simulations for flight trajectory optimization. The aircraft model was A320-200s, which is pre-dominantly utilized in Southeast Asia for short to medium range flights. Fuel savings were computed for selected routes, and were compared with that of existing operations and flights simulations, which revealed significant fuel savings. The research also determined the coefficients of ATCOs’ workloads and demonstrated dynamic sectorization in selected airspace of Southeast Asia. It was found that dynamic sectorization was more efficient than static sectorization in balancing the workloads of ATCOs, reducing the standard deviation by 50% and the balance of workloads among sectors by 12.9%.

“…In the meantime, several studies have also been conducted using either Jet-A1 or JP8 as the fuel [1,[5][6][7][8][9]. Most of these studies cover not only the thermodynamic analysis part, but also the economic [5,7] and sustainability factors [1,9]. However, all of them take a turbofan engine with separate exhaust as the case study.…”

Abstract. In this study, the theory, methods and example application are described for a CF6 high-bypass turbofan engine with mixed exhaust flow based on exergo-sustainable point of view. To determine exergetic sustainability index, the turbofan engine has to undergo detailed exergy analysis. The sustainability indicators reviewed here are the overall exergy efficiency of the system, waste exergy ratio, exergy destruction factor, environmental effect factor and the exergetic sustainability index. The results obtained for these parameters are 26.9%, 73.1%, 38.6%, 2.72 and 0.37, respectively, for the maximum take-off condition of the engine. These results would be useful to better understand the connection between the propulsion system parameters and their impact to the environment in order to make it more sustainable for future development.
