Title:
TURBO FAN ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/092910
Kind Code:
A1
Abstract:
Provided is a turbo fan engine (TF) provided with a power transmission device which switches main shafts (MS), connected to a starter/generator (SG) in a power-transmittable manner, between a state during starting and a state after starting. The TF is provided with a first MS and a second MS, and the power transmission device is provided with first, intermediate, and second shafts which are arranged coaxially, and a clutch. The first shaft is connected to the first MS with a bevel gear therebetween. The intermediate shaft is arranged on the outside of the first shaft and is connected to the SG with a bevel gear therebetween. The second shaft is arranged on the outside of the intermediate shaft and is connected to the second MS with a bevel gear therebetween. When the inner of any two of the first, intermediate, and second shafts that are adjacent to each other tries to rotate faster than the outer thereof, the clutch causes the shafts to engage each other and rotate at the same speed to transmit power. When the outer of said two shafts tries to rotate faster than the inner thereof, the clutch disengages the shafts so as not to transmit power.
