Twin-shaft turbine engine for aircraft, has main drive pinion module driving movement transmission shafts extending coaxially, and driving unit comprising high and low pressure drive pinions integrated to high and low pressure rotors

摘要

The engine has a driving unit comprising a high pressure drive pinion (9) integrated to a high pressure rotor (2) at the proximity of an upstream end of the rotor. The driving unit has a low pressure drive pinion (7) integrated to a low pressure rotor (1) in the downstream of the rotor (2). A main drive pinion module (29) drives movement transmission shafts (11, 12) that extend coaxial to each other. An independent claim is also included for a turbine engine mounting method.
