Refinement and expansion of area of use methods of calculation of characteristics of lattices of profiles

Abstract

Laws of course of characteristics of lattices of profiles are analyzed, the method of their extrapolation and construction of a field of these characteristics, including contraflows (arising is offered periodically during a surge). Course of lines nominal (on Howell) modes and lines of the maximum turn of a stream is In the field shown. The zone where the received Kazandzhan P. K regression relation (for angles of entry and an exit from a lattice with the account geometry) have the minimum error (on the first derivative and on antiderivative) in comparison with results of purgings is revealed. Particular treatments and points on characteristics of lattices of profiles are allocated. Universal relations for calculation of parameters in these points depending on geometry of blade wreaths are received.
