AIRCRAFT ENGINE UNIT COMPRISING AN IMPROVED FRONT ENGINE ATTACHMENT

摘要

An aircraft engine unit comprising an engine, a mast and an engine connection connecting the engine and the mast. The aircraft engine unit includes a front engine attachment of the engine connection which comprises at least one front rod connecting the primary structure of the mast and the core of the engine and which assures the take-up of vertical forces, and at least one connection connecting the primary structure of the mast and the fan casing of the engine and which assures the take-up of forces that are horizontal and perpendicular to the axis of rotation of the engine and/or a torque about the axis of rotation of the engine.

1. An aircraft engine unit comprising an engine, a mast and a nacelle in which there is positioned the engine,
the engine comprising:
a core which comprises a stator and a rotor, the rotor pivoting about an axis of rotation relative to the stator,a fan connected to the rotor and positioned in a fan casing, the mast comprising a primary structure connected to the engine by an engine connection which comprises:
a rear engine attachment which connects an intermediate part of the primary structure and the core of the engine,a front engine attachment which connects a front end of the primary structure and the engine, andat least two thrust rods,the front engine attachment comprisingat least one connection which connects the primary structure of the mast and the fan casing of the engine, andat least one front rod which connects the primary structure of the mast and the core of the engine, andwherein each front rod is connected at a first end to a front end of the primary structure of the mast by a connection pivoting about a horizontal axis perpendicular to the axis of rotation, and is connected at a second end to the core of the engine by a connection pivoting about a horizontal axis perpendicular to the axis of rotation.
