基于MBSE的民机审定试飞场景设计

面向适航审定的飞行试验是验证民用飞机满足设计需求、表明适航条款符合性、形成审定证据的高风险、高成本的重要取证活动。定义和设计民机审定试飞场景是进行民机适航审定飞行试验的前提。由此提出了基于适航符合性证据链的审定试飞场景设计方法及流程。以“符合性证据链”为核心，规划了逻辑严密、可追溯的适航符合性证据。通过引入基于模型的系统工程(model-based systems engineering, MBSE)方法，实现了审定试飞场景符合性证据链构建过程的模型化。为提升可操作性,以适航要求“地面航向操纵性”为典型案例,演示了审定试飞场景需求分析、设计与需求确认的过程。最终设计得到的审定试飞场景能够支持民机适航审定飞行试验的开展。

Design of civil aircraft certification test flight scenario based on MBSE

The flight test for airworthiness certification is a high-risk and high-cost important forensic activity to verify that the civil aircraft meets the design requirements, demonstrates the compliance with the airworthiness clauses, and forms the certification evidence. Defining and designing the test flight scenario of civil aircraft certification is a prerequisite for conducting airworthiness certification flight test. The design method and process of the certification test flight scenario based on the airworthiness compliance evidence link are then proposed. Taking "compliance evidence link" as the core, the logical and traceable airworthiness compliance evidence is planned. The model-based systems engineering (MBSE) method is introduced to realize the modeling of the process of constructing the compliance evidence link for the certification test flight scenario. In order to improve the operability, taking the airworthiness requirement "ground heading maneuverability" as a typical case, the process of requirement analysis, design, and requirement confirmation of the certification test flight scenario are demonstrated. The final designed certification test flight scenario can support the conduction of the civil aircraft airworthiness certification flight test.
