中文摘要:现代民机广泛采用数字式电传飞控系统,它有利于飞机减重、飞行品质改善、飞机维护性改善等。民机电传飞控系统需满足严格的安全性与可用性要求,保证飞机取证与运营可靠性。故障检测与容错技术是实现高度安全可靠电传飞控系统的关键。该文阐述了已应用于现代民机的故障检测与容错技术,重点介绍了波音、空客公司故障检测与容错技术应用于民机设计的成功案例,对未来民机容错技术发展进行了探讨与展望。
英文摘要:Electrical flight control system(EFCS) has been widely applied in modern civil aircraft and brings benefits such as weight saving, improvement of flying qualities and improved maintenance strategies. EFCS is designed to meet very stringent requirements in terms of safety and availability, in order to satisfy aircraft certification and airline reliability. Fault detection and fault tolerance technology are the key to realize highly dependable EFCS. This paper deals with the industrial practices on fault detection and fault tolerance for civil aircraft, especially the state of the art and experiences from Airbus and Boeing Company. Several detail examples of fault detection and fault tolerance have been introduced. Finally, future trends and challenges for fault tolerance technology are presented.
