基于适航安全的民用飞机电传飞控系统架构设计考虑

Architecture Design Consideration of Fly-by-Wire Flight Control System for Civil Aircraft Based on Airworthiness and Safety

在民用飞机电传飞控系统架构设计中,安全性需求占据着至关重要的地位。本文介绍了民用飞机适航规范和行业准则,梳理了系统架构设计要求,从设计前的需求论证、设计中的权衡以及设计后的评估验证三个方面,对适航安全性在飞控系统架构设计中的具体体现进行了研究,并以滚转轴(纵轴)基本控制功能为例,提出了满足适航安全要求的设计考虑,为民用飞机电传飞控系统架构设计提供参考。

Safety requirements play an important role in the architecture design of the fly-by-wire flight control system of civil aircraft.This paper introduces civil aircraft airworthiness standards and industry standards,and analyzes their requirements for system architecture design.The embodiments of airworthiness and safety in flight control system architecture design are studied from the following three aspects:requirements demonstration,design tradeoff and verification.Taking the basic control function of the roll axis as an example,the design considerations to meet the airworthiness and safety requirements are put forward,providing a reference for the architecture design of the fly-bywire flight control system of civil aircraft.
