FIELD: gas-transfer facilities.
SUBSTANCE: proposed cooling system of gas-turbine engine includes air intake, axial flow, fan and driven gate with turnable louvers. Louvers in gate are fitted on shaft asymmetrically relative to axes of their rotation, being installed to that smaller length parts are pointed to side of air intake. Owing to asymmetrical arrangement of louvers on shaft, when air passes through louvers, moment of forces for opening the louvers exceeds moment of force for closing the louvers which excludes overlapping of passage section of gate, thus providing reliable delivery of air for cooling gas-turbine engine.
EFFECT: provision of possibility of changing the system on operating sets at minimum labor input and cost of work.
