| 摘 要： | 针对目前风洞铰链力矩实验中的一种三分量片式结构铰链力矩天平没有轴向力测量元件的不足,提出一种切实可行的四分量片式结构铰链力矩天平设计方案,进行了物理样机的研制,应用于某模型升降舵风洞铰链力矩实验中。实验结果与理论分析获得了良好的一致性,在舵面偏角为21°时,由忽略轴向力测量带来的舵面法向力系数相对误差百分比为14.7%,舵面弦向压心位置相对误差百分比为17.2%。

| Abstract: | For resolve the non-axial force measurement limitations of three-component hinge moment balance on wind tunnel control flap test,a operable design plan of four-component hinge moment balance is put forward in this paper,then a physical prototype was application in the elevator experiment.The result shows that the experiment result and theoretical analysis have good consistency when elevator angle is 21 degree,normal force coefficient relative error is 14.7% and control flap＇s pressure center position relative error is 20%,which ignore the axial force measurement. |
