Model-based System Safety Assessment of Aircraft Power Plant

Abstract

The aircraft power plant becomes even harder since the complexity and integrity of system function, and the traditional system safety analysis, influenced by the personal skills and experience of analysis, may cause error and system failure condition and effects. The paper presents a new approach called Model-based Safety Analysis (MBSA) for complex system, and the process of MBSA is studied by linking function modeling using formal language and fault propagation based on Altarica, and the given method can be introduced to aircraft power plant system in order to unify the process the system development and system safety assessment, and versatility and feasibility of the approach are demonstrated with the case study of aircraft power plant.
