The method of analytic-visualized data processing of physic modeling hydro-aerodynamic processes 
in physical prototypes minor elements of power equipment was developed. 
The method allows obtaining knowledge about the hydro-aerodynamic processes 
and to reduce hydro-aerodynamic resistance in these elements. 
It based on information models of visual data of hydro-aerodynamic process 
and structural primitives and on modified method of their creation – 
clusterization and classification. The method of analytic-visualized data processing, 
which was used in system of technical diagnostics, 
allowed solving vital scientific-applied problem of increasing efficiency 
of hydro-aerodynamic process in power equipment.
