Abstract
This paper presents a comprehensive conceptual design study for the next generation of single-aisle passenger transport, focusing on reducing fuel burn and noise through optimization around mission-based parameters. While much of the industry’s efforts have centered on advanced configurations unlikely to be developed and certified soon, this study emphasizes the importance of optimizing conventional aircraft designs to bridge the gap until their arrival. Technologies expected to mature by 2035 are identified and infused into a large single-aisle aircraft to establish a baseline, primarily because the largest market share among other classes of vehicles, followed by optimization driven by mission-based parameters. 2035 technologies alone resulted in a 19.8% reduction in block fuel for the default design range. Reducing the cruise Mach number and incorporating natural laminar flow further decreased the fuel burn by 8.2%. The reduced range optimization yielded an additional fuel saving of up to 4.1%, though the returns diminish with decreasing range. Overall, the total fuel burn reduction compared to the 2018 Technology Reference Aircraft is estimated to range from 29.2% to 30.8%. This work highlights the potential for significant efficiency improvements in next-generation civil aviation while leveraging mature technologies until the arrival of novel configurations.
