摘要
本文对航空器压力测量管路系统的迟滞特性与误差进行了理论分析与实验研究。推导出有实用价值的等速率输入波形下压力测量管路系统迟滞特性的计算公式。设计和建立了测定管路压力迟滞的实验系统并进行了实验。将管路压力滞后的计算值与实验结果进行了比较,表明在一定的范围内吻合良好。
Theoretical and experimental investigations of pneumatic lag characteristics in vehicle's pressure sensing devices is presented. An useful formula which can be accurately used to predict the lag charactevistics of pneumatic sensing system subjecting to pressure input with constant rate is given. The procedures used to experimental measurement of pressure lag are described. Comparisons of theoretical Calculations and experimental results are given and show they are in good agreement.
