发动机热试车数据测量误差分析及处理方法

Error analysis and processing of engine hot test data

对发动机试车测量误差进行了分类并提出了消弱误差的方法,特别是对数据处理中最小二乘法的应用以及推力零位误差的消弱方法进行了阐述。验证表明,这些分析及方法对数据误差的消弱是有效和可行的。

The classification of measured error in the process of engine test and the way to weaken the error are proposed. The application of least squares method in the specifical data processing and the method to weaken the data zero error are presented. The confirmation result shows that the analysis on weakening of the data errors is valid and feasible.
