对装在F—111B飞机敞开的武器舱里的“不死鸟”空空弹编制了载飞振动研究大纲。此大纲包括导弹飞行测试大纲和为试验室振动试验而作的飞行振动环境的予测。空空弹的振动环境试验是用(参考文献1)其中一位作者所研究的统计方法来确定的。这种方法根据高性能飞机里以三种不同的安装方式的飞行试验所测数据得出的,此方法总括了对飞行数据予测和分析的结果所作之很详细的说明。载飞振动试验按导弹结构于十五个测点上进行测量。其数据是用符合于予测技术的

A fly-by-vibration study program was prepared for “NDV” empty-space bombs contained in open arms of the F-111B aircraft. This outline includes the Missile Flight Test Program and the flight vibration environment for the laboratory vibration test. Vibration tests of the air-to-air space were performed using the statistical methods studied by one of the authors (Reference 1). This method, based on data from flight tests of three different installations in high-performance aircraft, provides a very detailed explanation of the results of the predictions and analyzes of the flight data. Fly-vibration test The missile structure was measured at fifteen measuring points. The data is in line with the predictive technology
