摘　　要：故障注入是一种基于试验的测评方法,是飞行器综合健康管理的重要组成部分,在提高飞行器的安全性方面具有重要作用。本文介绍了故障注入技术的基本原理,详细阐述了故障注入的各种实现方法在飞行器中的应用现状,重点分析了故障注入技术在飞行器结构、防热、液压、机械等非电系统应用中的关键技术以及存在的技术难点,并展望了该领域的发展。Faults injection technologies, which are important component of integrated vehicle health management （IVHM） system and can be used to estimate the safety status of vehicles by lots of experiments, are being paid more and more attention. Based on the principle of faults injection, several methods of faults injection and their applications in aircraft are described in detail. For different systems or subsystems of aircraft, the key-point of different faults injection technologies have been discussed. Especially, for non-electronic system, including the structure system, thermal-protection, hydraulic and mechanical system, there are some particular technologies and updated promotions which may make the system health management more easy and convenient. All the in- vestigation on faults injection technologies will be useful to the IVHM system and its implement.
