FIELD: engines and pumps.
SUBSTANCE: proposed engine comprises a central assembly support, a gearing assembly and a flexible support. The central assembly support forms an inner circular wall for axial contour comprising the first mounting device. Gearing assembly engages shaft and fan running about axis. The flexible support couples the gearing assembly with the central assembly support and comprises the second mounting device interfaced with the first mounting device to transmit torque from one mounting device to another. During disassembly of the engine front section, the access is provided to forward-facing fasteners that secure the central assembly support to the flexible support, bearing the gear assembly, and these fasteners are removed. Then, the first and the second mounting devices made respectively on the central assembly support and flexible support are disengaged.
EFFECT: group of inventions allows to simplify dismantle of assembly of gearing of the gas turbine engine.
