Description of the geometry of the outer surface the pen of the working blades of the axial compressor GTE twodimensional splines of degree 2 defect 1

Abstract

The algorithm for the construction of the matrix in the form of two splines of degree 2 and defect 1. On the basis of the developed method of description of the outer surface of the operation the vanes of the axial compressor GTE and built a mathematical model of the outer screen surface of the concrete of the rotor blade, which allows to determine the coordinates of any point on its outer surface. This study is the basis for creating techniques of using two-dimensional splines of degree 2 in the mathematical description of the scheme of stacking of layers of composite materials composite in the working blade of the axial compressor GTE and the subsequent use of the model of stacking of layers in the calculations for strength, stiffness and vibrations.
