Abstract
The measurement results of the geometric parameters of the parts play an important role in the assembly process of gas turbine engine assemblies The article provides an analysis of the problems of reducing the measurement uncertainties of gas turbine engine parts. Significant uncertainties in the measurement of the geometric parameters of gas turbine engine low-rigid parts are caused by uncertainties in the processing algorithms for measured data. The ways of improving the processing algorithms for measured data are proposed, they are based on taking into account the contact of the surfaces during assembly and the rigidity of the measured parts. Theoretical and experimental studies of the uncertainties in the processing algorithm for measured data are carried out, using the example of measuring the geometric parameters of a low-rigid part of the “spacer” type. Comparison of three variants of the processing algorithms for measurement results are presented.
