- W2997866734 abstract "In order to achieve the aviation goals set by agencies around the world such as NASA and ACARE to reduce fuel consumption, carbon emissions and noise, academia and the industry are researching innovative solutions to the problem, including unconventional aircraft designs and alternative propulsion systems. Research on propulsion systems include improving fuel efficiency of gas turbine engines, alternative energy sources (battery, fuel cell) and architectures such as hybrid-electric and turboelectric. With many possible architectures, the ability to quickly assess multiple architectures could help focus resources for the further research and development of promising designs, and potentially identifying the optimal architecture. The objective of this paper is to propose a framework for rapid and efficient exploration and evaluation of propulsion system architectures. There are three aspects to this problem – representation, evaluation and exploration. To this end, generalized parameters that can uniquely represent different propulsion system architectures with one or more energy sources are defined. Using these parameters, equations to evaluate the performance of the system, such as the global chain efficiency, thrust specific power consumption, and energy specific air range, are derived. A method for exploration of the architecture space and identification of feasible architectures is then described. In this paper, the ability of the parameters to represent all architectures is demonstrated for the electrified propulsion design space, which is then explored by parametrically varying the parameters. Results are demonstrated for a 50-passenger regional aircraft." @default.
