TWO-STAGE GAS TURBINE ENGINE WITH PTO-DEVICE AT LOW-AND HIGH-PRESSURE ROTORS, GAS TURBINE ENGINE PTO-UNIT AND METHOD OF GAS TURBINE ASSEMBLY

摘要

FIELD: engines and pumps.;SUBSTANCE: proposed engine comprises low- and high-pressure rotors, extra gearbox and transfer shaft drive to transfer drive force to extra gearbox. Said drive comprises high-pressure gear wheel on high-pressure rotor shaft, low-pressure gear wheel on low-pressure rotor shaft and p.t.o-unit engaged with drive gear wheels. P.T.O.-unit comprises housing and two p.t.o.-gears. High-pressure p.t.o.-gear engages with high-pressure drive gear, while low-pressure p.t.o.-gear is in mesh with low-press p.t.o.-gear. Another invention of proposed set relates to p.t.o.-unit of proposed gas turbine engine. One more invention relates to method of assembling said gas turbine engine that comprises mounting high-pressure rotor, p.t.o.-unit, transfer shafts in p.t.o.-unit and low-pressure rotor.;EFFECT: simplified design and assembly.;9 cl, 1 dwg
