飞行试验阶段航空装备可靠性评估方法

Study on Reliability Evaluation Method of Aviation Equipment in Flight Test Stage

目前,飞机试飞阶段遇到的情况复杂多样,对于可靠性评估提出了极大的挑战,传统可靠性评估方法在试飞过程中逐渐显得力不从心,因此,通过系统分析不纠正、即时纠正、提前纠正、延迟纠正、部分即时纠正、单设备复杂纠正和多设备复杂纠正等飞机试飞阶段实际遇到的情况,提出了相应的可靠性评估方法,可实现更精确评估试飞阶段飞机的可靠性结果,为工程推广应用奠定了良好的基础。

At present,the situation encountered in the flight test stage of aviation equipment is complex and varied,which presents a great challenge to the reliability evaluation,and the traditional reliability evaluation method’s ability gradually appears to be not equal to wishes in the course of flight test,so non-correction,immediate correction,early correction,delay correction,partial instant correction,single-device complex correction,and multi-device complex correction and other encountered conditions during the flight test stage are analysed.The corresponding reliability assessment method is put forward.The reliability results in the flight test phase of aviation equipment can be assessed more accurately.It has set a good foundation for the popularization and application of the project.
