Spitsyn V. Geometrical modelling of compressor blade apparatus

An object is the blade apparatus of compressors of gas-turbine engines; a target is development geometrical models, algorithms and computer programs of calculations and visualisation on personal computer of axial compressors blades necessary to determine their rational forms and further machining on the modern technological equipment; methods - solution of tasks is carried out on the basis of methods of the applied geometry and computer graphics; theoretical and practical results - the effective methods for solution of complex of tasks of geometrical modelling of compressor blade apparatus both on the stages of their design and further machining on modern technological equipment; novelty - in this thesis for the fist time were proposed the geometrical models of axial compressor blade apparatus which allows to increase their efficiency, the model of skeleton line modelling on the base of given curvature diagram, the model of non-symmetric profile; the method of blade working surfaces modelling, influence of geometrical parameters on the blade shape and surfaces was determined; degree of adoption - the result of investigation are introduced in SP NPKG "Zorya"-"Machproect" (Nikolayev), OAO IPP "Energiya" (Krivoy Rog), ZMKB "Progress" (Zaporozhie), FGUP MMPP "Salute" (Mos-cow), OAO NPO 'Saturn' (Ribinsk); the sphere of utilization is the blade apparatus of axial compressor.
