Second Law Based Integrated Thermoeconomic Modeling and Optimization Strategy for Aircraft/Aerospace Energy System Synthesis and Design.

摘要

As part of this project over the past two years, a general methodology (ILGO) for the decomposed synthesis/design optimization of highly coupled, highly dynamic energy system has been developed applied to an aircraft propulsion sub-system (PS) coupled to an environmental control sub-system (ECS) and is being applied to a combination of coupled aircraft sub-system, namely, a PS, and ECS, a TMS (thermal management sub-system) and a SS (structural sub- system). It is our intention at the completion of this project to have solved this problem in its entirety, resulting in a Ph.D. dissertation already completed and submitted as our annual report in year one of this project and an M.S. thesis. The latter of these will serve as our final report for the final phase of this project to be complete next year. In the meantime, however, for the purpose of this project, some preliminary results are presented showing the influence of the various coupling function (an integral part of ILGO) on the unit-level and system-level, unit-based synthesis/design optimization of the PS, ECS, and TMS (i.e. fuel loop sub-system (FLS) and vapor refrigeration /PAO loops sub-system (VC/PAOS)). Furthermore, for the time being, no decision variables are used for the SS, which is solved as an integral part of the PS.
