TWIN SPOOL TURBINE ENGINE WITH POWER TAKE-OFF MEANS ON THE LOW-PRESSURE AND HIGH-PRESSURE ROTORS, POWER TAKE-OFF MODULE FOR THE TURBINE ENGINE AND METHOD OF ASSEMBLING THE TURBINE ENGINE

摘要

The invention relates to a twin spool turbine engine comprising a high-pressure rotor and a low-pressure rotor, at least one accessory gearbox, a drive means, driving coaxial transmission shafts that transmit movement to the accessory gearbox, characterized in that the drive means comprises a high-pressure drive pinion secured to the high-pressure rotor near its upstream end, a low-pressure drive pinion secured to the low-pressure rotor upstream of the high-pressure rotor, and a power take-off module in direct mesh with the drive pinions, driving the transmission shafts. By virtue of the invention, the transmission shafts run coaxial with one another and therefore pass through a single arm. The use of a power take-off module simplifies the mechanism. The turbine engine is simpler to assemble.
