摘要: 叙述了单分量和三分量时差动导数天平的性能、测量原理和静、动校结果。单分量时差动导数天平测量mz/α·时,用GBM-4动导数标模作动态校测。三分量时差动导数天平可测量偏航、俯仰和滚转时差动导数(例如my/β·,mz/β·和mx/β·等),用类似于航天飞机外形的标模作动态校测。

Abstract: The function, the measurement principle, and the static dynamic calibration of the balances of the one component and the three components dynamic derivatives due to plunging are described. The balance of the one component dynamic derivative due to plunging measured m z/ α· with the GBM-4 dynamic derivative standard model. The balance of the three components dynamic derivatives due to plunging measured yawing, pitching, and rolling dynamics derivatives due to plunging (m y/ β· ,m z/ β· 和m x/ β· ) with a space shuttle-like standard model.
