Abstract
This work addresses the optimized integration of new types of electrical power system energy storage and energy generation devices into advanced electrical power systems for commercial airplanes. The objective of this research is to identify how new energy generation and storage system technologies, such as batteries, fuel cells and super capacitors, can be successfully integrated into an optimized and more efficient future airplane electrical power system architectures with success being measured from the standpoint of improvements in airplane, efficiency, reliability and maintainability. The baseline airplane electrical power system architecture that was chosen as a reference starting point for this study is a scaled model of Boeing's 787 "More Electrical Airplane" (MEA) due to its significantly increased electrification in comparison to all other commercial transport airplanes flying today. The 787 power system is unique in that it replaces nearly all of the pneumatically powered systems and some of the hydraulically powered systems with electrical power. This system architecture was incorporated on the 787 in order to provide significant advancements in airplane efficiency and to enable increased airplane performance and range along with decreased fuel burn and an associated decrease in emissions detrimental to the environment.The 787 MEA also incorporates a much more distributed electrical power system architecture and makes significantly increased use of power electronic conversion technology. Similarities can thus be drawn between the MEA and what is occurring with microgrids in the utility industry and electric and fuel cell powered automobiles in the transportation industry. Consequently technical information can be drawn from those industries technologies that potentially is useful in the research and development of an advanced MEA.Through the combination of the simulation and analysis this research shows that incorporation of these new energy generation and storage systems into a future MEA electrical power system along with changes in system conversion systems, electrical loads, and the overall electrical power system architecture would result in a significant increase in overall airplane efficiency along with other improvements for a future MEA.
