METHOD OF MODELLING BATHTUB OF BLADE Russian patent published in 2019 - IPC G06F17/50 F01D5/20 

FIELD: machine building.

SUBSTANCE: invention relates to simulation of at least part of bathtub (2) of turbine blade (1). Disclosed is a simulation method, characterized in that it includes, using data processing equipment (11) means (10), steps of: (a) parameterising volume (V) displaying said portion of bathtub (2) as a collection of sections (20) extending from support transverse surface (S) of blade (1), wherein blade (1) physically comprises sections (20), and each section (20): is connected to elementary surface (Si) selected from plurality of elementary surfaces (Si), forming separation of at least part of said support transverse surface (S); and is determined by section height relative to said support surface (S); (b) determining optimized values of sections heights relative to a given aerodynamic and/or thermal criterion; (c) at interface (13) of said equipment (10) reproduce determined thus values.

EFFECT: technical result consists in enabling analysis of various geometry of blades with reduced use of computer resources.
