- W2332325192 abstract "As part of the efforts to better assess the effect of aviation on the environment, the need for an improved understanding of noise, emissions, and fuel burn interdependencies has been recognized. A suite of analysis tools has been developed by the FAA, in conjunction with NASA and Transport Canada to inform environmental policy making and help shape the future of air transportation. As part of this suite, the Environmental Design Space (EDS) is tasked with the evaluation of the impact of new technologies on vehicle performance through simulation-based analysis of engines and airframes. To ensure the credibility of the EDS model, the assumptions, methodologies, and results must be reviewed through a formal, repeatable, and transparent assessment. This paper outlines the challenges faced, and the approach taken, in the assessment of the EDS model. The development process is divided into three distinct phases. The calibration process demonstrates the ability of the EDS model to reproduce representative aircraft. Using only public domain data, a combination of input parameters is established to approximate existing engines and airframes. The sensitivity analysis explores the relationship between model inputs and outputs while aiding the verification of physical trends. A methodology for variable screening and subsequent determination of input settings is established. Finally, the trade space exploration allows for the determination of a fleet of aircraft that represents the technology space through Pareto-front identification and selection. In each phase, error and uncertainty are quantified and propagated to communicate the probabilistic results of EDS to the other tools within the suite. Future work will focus on the details of implementing the approach for development and assessment." @default.
