Information Model for Estimate of the Geometric Parameters between the Surfaces Trapezoidal Shape in the Measurements of Compressor Blades of GTE
Abstract— The paper describes the developed method and the measured information processing model
in coordinate measurements of geometric parameters describing the mating surfaces of trapezoidal
shape by an example of compressor blades of GTE. The considered pairing includes a blade root and
a turbine engine disk slot. Trapezoidal is formed by three planes, including two sides and one lower.
The type of mating achieved in the assembly process is considered in the proposed method and the
model in the contrast to traditional algorithms and techniques .The results of proposed model testing
and the results of the comparison estimates of geometric parameters obtained by using the proposed
model and the traditional methods of treatment. We investigate the influence of the errors of form and
microroughnesses on accuracy of the estimation of geometrical parameters characterizing the mating
surfaces of trapezoidal shape.
Index Terms— Least square method, compressor blade, assembly.
