Abstract
A gas turbine engine including a gas generator module and a reduction gearbox module. The gas generator module has an axis which extends longitudinally along a centreline of the gas generator module, and the reduction gearbox module has an axis which extending longitudinally along the centreline of the reduction gearbox and is offset from said generator axis. The reduction gearbox is driven by an intermediate shaft angled relative to the turbine output shaft.
Claims20
A gas turbine engine comprising:
- a gas generator module having a turbine shaft for providing rotating output power;
- and
- a reduction gearbox module having a gearbox input shaft and a main output power shaft, wherein the gearbox input shaft is drivingly connected to an intermediate drive shaft, the intermediate drive shaft being drivingly connected to the turbine shaft, and wherein the intermediate drive shaft is disposed at an angle to the turbine shaft.
A gas turbine engine comprising:
- a gas generator module, the gas generator module including a compressor portion, a combustor portion, and a turbine portion;
- and
- a reduction gearbox module adapted to drivingly connect the gas generator module to an output power shaft, the reduction gearbox module being disposed substantially laterally beside the gas generator module.
A gas turbine engine comprising:
- a gas generator module having an turbine shaft for providing rotating output power;
- and
- a reduction gearbox module adapted to drivingly connect the gas generator module to an output shaft,
- wherein the reduction gearbox module has an input shaft which is drivingly connected to an output turbine shaft of the gas generator module through a bevel gear on the turbine shaft.
