AIRCRAFT TURBINE ENGINE WITH PLANETARY OR EPICYCLIC GEAR TRAIN

摘要

The invention relates to an aircraft turbine engine, comprising a low-pressure body including a low-pressure shaft (24), means (44) for collecting power on said low-pressure shaft, and a fan (28) driven by said low-pressure shaft via a reduction gear (32), said reduction gear comprising at least one first element (50) constrained to rotate with said low-pressure shaft, at least one second element (56) constrained to rotate with said fan, and at least one third element (52) connected to a stator housing of the turbine engine. The invention is characterized in that said at least one third element is connected to said stator housing by disengageable connection means (60) comprising at least one member that is movable from a first position in which said at least one third element is rigidly connected to said stator housing, to a second position in which said at least one third element is disconnected from said stator housing and is free to rotate about said longitudinal axis.
