测量过程对航空航天行业至关重要，其产品必须遵守严格的法规和客户要求。此外，测量不确定度正迅速成为认证机构和客户的一项要求。必须对所有需要在测量结果中添加不确定度声明的过程进行不确定度评估。为了维持已定义的质量标准，航天制造公司需要确定所有受益于陈述不确定度水平的测量学科，并定义用于复杂测量过程的不确定度计算方法。为了确定最合适的方法来评估复杂航空部件的不确定度，人们进行了广泛的研究，并应用案例研究来评估不同航空部件的应变片校准测试不确定度。本研究开发了一个通用框架，帮助评估所有单独的不确定度来源，完成了《测量不确定度表示指南》建立的框架。从案例研究的结果中提取了结论。进行的研究有助于更好地理解测量过程和导致较低不确定度的良好做法。结果将帮助制造公司了解测试的不确定因素，如何减少这种不确定度，以及在测试过程中进行的测量的可靠性。
Measurement processes are critical to the aerospace industry, which products must follow strict regulations and customer requirements. Additionally, measurement of uncertainty is fast becoming a requirement from both certification bodies and customers. An uncertainty assessment must be carried out for all processes that need to add an uncertainty statement to the measurement result. In order to maintain defined quality standards, aerospace manufacturing companies need to identify all measurement disciplines that benefit from stating the level of uncertainty and define a methodology to calculate it for complex measurement processes.An extensive research has been conducted in order to define the most appropriate methodology to assess uncertainty on complex aerospace components and a case study has been applied to assess the strain gauge calibration test uncertainty of different aerospace components.This study develops a generic framework, which helps the assessment of all individual sources of uncertainty and completes the one established by the Guide to the Expression of Uncertainty in Measurement. Conclusions have been extracted from the outcome of the case study.The conducted research contributes to a better understanding of measurement processes and good practices that lead to lower uncertainty. The outcome will help manufacturing companies to be aware of the contributors of uncertainty to the tests, how to reduce this uncertainty and the reliability of the measurements taken during the process.
