Abstract

The regularities of the characteristics percolation of the cascades identified by Howell and the method of their calculation using the P. P. Kazanchan regression dependence are considered. There is offered usage of linearization methods, substantiated for simplified performance axial compressor stage by L. E. Olshteyn, for cascades. To do this, the authors derived the corresponding optional dependings.
