Civil Aircraft Electrical System Development Using Model-Based System Engineering

Abstract

As one of the key systems of modern civil aircraft, Electrical System (ES) plays an important role in all flight phases of the aircraft. Considering the needs of the electrical system, based on the analysis of interaction process of civil Electrical System design and safety assessment, Doors and Rhapsody are used to accomplish the Requirement Analysis, Functional Analysis and Design Synthesis of electrical system in this paper. The use case model, function analysis model and verifiable state machine model of the electrical system are established to ensure the requirements are accomplished by system architecture. Finally, the interactive interface of panel diagram is developed to complete the simulation of the system model according to design requirements. The simulation shows that Model-Based Systems Engineering (MBSE) can greatly improve the efficiency and accuracy of the development of the electrical system.
