FIELD: thermal engineering. SUBSTANCE: gas- turbine unit gas has turbine and compressor mounted on common shaft and combustion chamber with fuel injectors. Combustion chamber communicates at its outlet directly with turbine inlet and at its inlet, with compressor outlet through jet apparatus. Fuel injectors communicate with fuel tank through shut-off starting valve and feed pump system. Jet apparatus is made in the form of injector communicating with external high-pressure air supply. Pump system is provided with separate variable-speed electric drive or turbine drive. EFFECT: improved performance characteristics due to facilitated starting of unit. 3 cl, 2 dwg
