FIELD: mechanical engineering; gas turbine engines. SUBSTANCE: two-rotor gas turbine engine has support charging system including supply air duct with air intake, low-pressure compressor and high-pressure compressor support charging spaces and turbine support charging space communicating through movable seals with gas-air duct of engine and with oil system spaces. Supply air duct is common for entire engine support charging system. Its air intake is furnished with change-over valve with at least two inlets spaced along gas-air duct. Air duct passing through low- pressure compressor trunnion is provided with throttle pack. Turbine support charging space communicates with turbine air duct and with high-pressure compressor front support charging space through additional air ducts. EFFECT: increased stability and efficiency of engine. 5 cl, 3 dwg
