摘要

为减少机载武器可靠性验证试验样本量和降低验证试验风险,通过对机载武器作战使用可靠性验证的工程需求、试验方案、统计模型、验证方法等进行研究,提出了一种利用研制试验数据和定型飞行试验数据的作战使用可靠性综合验证方法。针对机载武器的特点,根据变动统计理论,考虑性能验证与可靠性验证的要求,综合利用研制试验数据和定型飞行试验数据,给出作战使用可靠性综合验证方案,进而制定设计定型飞行试验方案。实例表明,在不改变生产方风险和使用方风险的情况下,该方法可有效地验证机载武器挂飞可靠性和自主飞行可靠性指标,显著地减少定型飞行试验样本量,大幅节约研制成本,并缩短研制周期。

Abstract

Reliability is one of the most important indexes of airborne weapon. To improve the precision of reliability demonstration on airborne weapon, the characteristics of the airborne are studied and a synthetic reliability demonstration method for airborne weapon is proposed with dynamic population statistics. According to the theory of dynamic population statistics, the environment factor and growth factor are introduced to describe the relation of reliability between varied environments and varied phases. Then, with the factors, the test data from various environment conditions and various develop phases is used to establish the reliability demonstration scheme. With the method, various test data is used synthetically to enlarge the sample size and increase the information for reliability demonstration. The present method is used to demonstrate the embarkation flight reliability and flying reliability of an airborne weapon. The result shows that the method is able to reduce the flying test samples and decrease the test charge and time.
