Abstract
AbstractThe concept of electrified aircraft propulsion (EAP) has garnered substantial attention and investigation due to its potential for mitigating fuel consumption, emissions, and noise. Present studies mainly concentrate on point design rather than systematic design space exploration. This paper considers the attainment of prescribed mission objectives as a paramount evaluation criterion and proposed a mission-oriented design and verification method based on model-based systems engineering (MBSE). Instead of using a general modeling language, this method develops a domain-specific metamodel library for EAP based on six meta-metamodels. A Mission-Operational-Functional-Logical-Physical (MOFLP) modeling methodology is provided to standardize EAP design process. Furthermore, the modeling process is integrated with the verification process by executable verification script. A case study about skydiving mission is conducted to verify the effectiveness of this method. The case results corroborate the utility of this method in the generation of an initial EAP solution. Such initial solution can serve as a fundamental benchmark for iterative design.
