FIELD: machine building.
SUBSTANCE: it is proposed to profile the grids of blade profiles, which are located on extreme axisymmetrical surfaces of working medium current and at least at one intermediate so that numerical values of special complex proportional to theoretical head of those grids can be approximately equal. Complex includes eight parametres, seven of which are geometrical parametres of grid, and the eighth one is design flow coefficient of the system.
EFFECT: increasing efficiency of turbine machine owing to equalising the head throughout the system width.
