民用飞机飞控系统需求确认方法研究

Research on Flight Control System Requirements Validation Method of Civil Aircraft

为获得性能、控制、重量和维修性等方面的收益,民机多采用电传飞控系统作为其实现平台。电传技术提升了飞控系统的综合性能,却增加了研发过程的复杂度和风险。在设计之初做好系统需求的确认工作,保证需求的正确性和完备性,进而保证设计实现的正确性,能有效降低研发风险和成本。在实际型号经验的基础上,提出飞控系统需求确认的过程及方法,为电传飞控系统设计研制提供支持。

To increase the proceeds of performance, controllability, weight and maintenance etc, most of the civil aircraft are implemented by the technique of Fly--By--Wire （FBW） flight control system. The FBW technique increases the system in- tegration level,it also augments the system＇s complexity and development risk. The requirement validation work shall be done to ensure the requirement completeness and correctness at the beginning of the design so as to enhance the design work success, and lower the risk and cost of development. This article proposes the validation process and method of FBW flight control system requirements based on the actual type aircraft experiences, it can provide references for civil aircraft FBW control system validation.
