“…In total, the cumulative fuel efficiency can be enhanced by 58.1%. The results are reasonably comparable to the results of the NASA ERA project [54], which has a fuel burn reduction of around 40%. The more aggressive fuel burn reduction of EWL project is due to the very significant LFC impacts.…”

Abstract:It is always a strong motivation for aeronautic researchers and engineers to reduce the aircraft emissions or even to achieve emission-free air transport. In this paper, the impacts of different game-changing technologies together on the reduction of aircraft fuel consumption and emissions are studied. In particular, a general tool has been developed for the technology assessment, integration and also for the overall aircraft multidisciplinary design optimization. The validity and robustness of the tool has been verified through comparative and sensitivity studies. The overall aircraft level technology assessment and optimization showed that promising fuel efficiency improvements are possible. Though, additional strategies are required to reach the aviation emission reduction goals for short and medium range configurations.

“…Although aircraft modeling and technology impact efforts have been extended to representative aircraft across all seat classes [10,11], this study focuses on the 300-passenger class large twin-aisle aircraft, consistent with the reference vehicle assumption for the N 2 technology generation noted in Table 1. To this effect, development of a reference vehicle with the integrated modeling framework was based on the Boeing 777-200ER with GE90-94B engines.…”

“…In recent work, Schutte et al [10,11] conducted a comprehensive survey of airframe and propulsion technologies expected to mature in the N 2 generation time frame based on their current TRL and assuming sustained support. That effort also produced a characterization of each technology in terms of subsystem attributes and correction factors within an integrated modeling capability for vehicle performance analysis and design.…”

The composition of an aircraft technology portfolio in response to environmental impact goals is of paramount importance for present and future aeronautics. Characteristics of the portfolio selection problem are ideally addressed via multi-objective genetic algorithm optimization. Methodological and practical considerations of this approach are examined while generating meaningful insight specific to a set of aircraft technologies expected to mature over the coming decade. Results allow for a detailed characterization of the set of Pareto-optimal technology combinations in terms of its corners, underlying performance tradeoffs, and salient topological features. High-impact technologies are resolved in terms of their pervasiveness across solutions in regions of interest. Because relativevalued environmental objectives can be exploited by the optimizer, the analysis is repeated with absolute-valued analogs to examine how the choice of objectives in this respect can affect the selection of technologies. The effect of resource costs associated with each technology, additively compounded for technology combination solutions, is also examined in this context by expanding the method to include a resource constraint. Accordingly, general features of the Pareto frontier in the objective space are characterized for varying degrees of resource constraint stringency.
