RÉSUMÉ

Methods of a decrease of the expenditure of energy for cooling high-temperature gas-turbine plants are given. It is shown that the decrease is maximum owing to a decrease in the total cooling air consumption, a decrease in the properties of air taken from a compressor to a cooling system, and a decrease in the air leakage from a cooling path into a flow-through turbine part. A method of multi-criterion optimization of a cooling system in multidimensional space of properties is designed with allowance made for functional and parametric restrictions. The use of this method for decreasing the expenditure of energy for cooling gas-turbine plants shows its high efficiency.
