Abstract

The mathematical model, minimizing the mass flow rate of cooling gas environment through the implementation of maximum strength potential is developed. The approach to the calculation of the optimum mass flow rates in the channels of the cooling shell turbomachinery components offered on the basis of the criterion of strength and heat balance equation. Features of the current state of stress, heat supply parameters to the boundary surface of the element and cooling characteristics are taken into account in constructing a mathematical model of the flow. The calculation of the optimum mass flow rate of the coolant for the turbine blade deflection held.
