轻型飞机纵向静稳定性试验的估算

The Estimation of Longitudinal Static Stability Flight Test for Light Aircraft

推导出了在试飞试验前对轻型飞机纵向静稳定性进行估算的公式,分别给出了握杆和松杆状态下静稳定性的估算方法。在此估算的基础上推导出了试飞试验时所要测的驾驶杆位移和杆力等估算式,进而提出了从试验数据到飞机中性点和实际纵向静稳定裕度的分析处理方法。

The estimation equations of longitudinal static stability of light aircraft are reduced. Stick fixed and stick free longitudinal static stability are analyzed respectively during the estimation. Based on the longitudinal static stability estimation, the equations of stick movement and stick force on flight tests are obtained, and the test data reduction methods for neutral points and actual longitudinal static margin are discussed.
