Civil Aircraft Auto Brake System Development Using Model-Based Systems Engineering

Civil aircraft auto brake system development based on Model-Based Systems Engineering(MBSE) technology is proposed in this paper. After requirements analysis, functional analysis and architecture synthesis three phases, use case model, function analysis model, tradeoff model and logical architecture of system are established in Rhapsody using Systems Modeling Language(SysML). Then a collaborative simulation mechanism combining Rhapsody/Simulink model is proposed to solve the defect that SysML can’t describe the continuous behavior of system. Collaborative simulation enables system designers to carry out comprehensive and timely verification of dynamic behavior and correctness of modeling by simulating the overall composition which greatly improves the efficiency and accuracy of development.
