固体火箭发动机地面试验性能参数测量不确定度评估

The Evaluation of Uncertainty in Measurement of Performance Parameters at a Solid Rocket Motor Static Test

首先阐述了A类不确定度与B类不确定度的评估方法,进而讨论了单通道测量结果与多通道测量结果的评估方法,最后阐述了通过抽样试验获得的样本数据,估计总体的性能参数范围这一参数估计问题。

This paper describes the evaluation method of uncertainty of class A and class B, discusses the evaluation method of measurement results through a single channel and multiple channels, and finally presents the parameter estimation problem that the range of the motor performance parameters is estimated with sample data obtained from a sampling test.
