A Design Method of Civil Aircraft Warning System Based on MBSE

Currently, the design approach for aircraft warning systems is predominantly reliant on documents, which is in contrast to the utilization of model system engineering being rel-atively limited. However, these techniques give rise to challenges such as insufficient design precision, poor model reusability, and complex structural design, which ultimately impact the quality and efficiency of aircraft research and development. To address these challenges, this paper proposes an aircraft warning system design method based on MBSE (Model-Based Systems Engineering). The method's core framework is built upon the Harmony SE approach, combined with the unique characteristics of the aircraft warning system. The design process involves three stages: “requirement analysis - functional logic analysis - architecture design”. In each stage, the method incorporates enterprise architect and SysML (Systems Modeling Language) to perform instance modeling and verify its effectiveness. Compared to traditional warning system design methods, this approach takes into consideration the specific characteristics of civilian aircraft warning systems, effectively mitigating common issues in the warning system design process while enhancing the efficiency of alarm system develonment.
