Mission reliability assessment for battle-plane based on flight profile
-
摘要: 针对作战飞机故障数据的特点,分析了作战飞机不同飞行剖面对其任务可靠性的影响.在此基础上,定义了飞行剖面折合系数、建立了作战飞机任务可靠性模型.基于该模型给出了作战飞机在不同飞行剖面下的任务可靠性评估方法.针对想定任务剖面,采用剖面合成的方法把其处理为典型飞行剖面的线性组合,并由此给出了作战飞机在想定剖面下任务可靠性的预测方法.实例表明基于飞行剖面的作战飞机任务可靠性评估方法合理可行,便于工程应用.Abstract: The mission reliability of battle-plane varied under different flight profiles. According to the characteristics of battle-plane's fault data, the flight profile conversion factor was introduced to establish the mission reliability model of battle-plane. Based on the model, the statistical inference method of failure rate for battle-plane was proposed, and the mission reliability was assessed under a given flight profile. For a scenario flight profile, a synthetic method was used to describe it as a weighted combination of typical profiles. Thus, the prediction method of mission reliability under the scenario flight profile was put forward by using the failure rates under typical profiles. The illustrative example shows that the method is reasonable and straightforward for engineering.
