Retrofitting and redesigning existing aircraft are potential paths toward achieving hybrid and all-electric flight. New design tools need to be developed to support the study of these new aircraft configurations. In particular, novel design frameworks need to account for system-level aspects, such as the use of space, the required level of electrification, thermal aspects, safety, and maintainability. This paper presents a multidisciplinary design analysis (MDA) framework focusing on aircraft system integration for future aircraft. Specifically, this paper focuses on the integration between aircraft sizing and subsystem sizing tools in an MDA workflow. In addition, the authors include an improved physics-based subsystem sizing methods valid for smaller, commuter, or regional aircraft. The capabilities of the developed framework and tools are presented for a case study covering the redesign of the DO-228 with a hybrid-electric propulsion system in combination with the electrification of its systems architecture and different subsystem technologies. 收起
