FIELD: power engineering.
SUBSTANCE: proposed gas-turbine power plant contains gas-turbine engine whose input device is furnished with stator flange. Rotor of free power turbine of gas-turbine power plant has shaft, useful load drive flange, labyrinth disk and radial-thrust bearing from side of input device. Relief space of free power turbine is formed by stator flange, labyrinth disk and input device housing. Labyrinth disk is installed by ring radial flange on ring radial flange of useful load drive shaft and is axially fixed by flange of useful load drive. Drive shafts of useful load and rotor of free power turbine are connected by torque transmitting device made, for instance, in form of splines and are also connected by coupling bolt.
EFFECT: improved reliability of gas-turbine plant by reducing stresses in drive shaft and axial forces acting onto radial-thrust bearing.
