| 摘 要： | 试验测量总是伴随有误差的产生,这里对音速喷管在航空发动机高压涡轮内部导向器流量测量系统进行分析,主要介绍误差来源、误差分配理论分析方法及其在实际仪器选择上的应用.以高压涡轮内部导向器前支撑流量测量为例,在给定测量系统总误差条件下,提出一种可行的误差分配方案.该方案满足精度要求,成本低.

| Abstract: | An experiment investigation is always with errors.In this paper,the error of the mass flow measurement system using sonic nozzle through the high-pressure internal guide vane is analyzed,mainly on the errors source,errors distribution theoretic analysis and its application on the influence of experiment instrument choice.An example related to the high-pressure guide vane is given to illustrate the applicable errors distribution method at a given mass measurement uncertainty.The system satisfy the accuracy requirements with low cost. |
