不确定度评定是风洞试验数据品质保证的一项重要内容。本文介绍美国AIAA风洞试验不确定度评定标准的制定背景和主要内容;分析研究标准中采用的不确定度概念、评定方法特点和原则、影响不确定度的误差源等有关问题。目的是为国内风洞试验数据评定方法与国际接轨提供参考。 Uncertainty assessment is an important part of wind tunnel test data quality assurance. This paper introduces the background and main contents of the evaluation standard of uncertainty of wind tunnel test in the United States AIAA. It also analyzes the concepts of uncertainty used in research standards, the characteristics and principles of evaluation methods and the error sources that affect the uncertainty. The purpose is to provide a reference for the domestic wind tunnel test data assessment methods to be in line with international standards.
