TURBOJET ENGINE SUSPENSION USING A DOUBLE REAR SUPPORT

摘要

Bypass turbojet engine comprising a fan casing (5) at the front and an exhaust casing at the rear, said turbojet engine further comprising a cold stream duct (7) which comprises an annular rear end connected to the exhaust casing and on which is positioned at least one attachment point (4) able to transmit the load from the exhaust casing to the structure of an aircraft, characterized in that a plurality of attachment points (4g, 4d) is positioned on the circumference of said annular rear end of the cold stream duct (7), said plurality of attachment points comprising either two points (4g, 4d) that are diametrically opposed on said circumference or at least three points that form a polygon through which the axis of symmetry of the cold stream duct (7) passes, and in that the turbojet engine is equipped with a rear suspension hoop (8) fixed to said attachment points and able to be fixed to the structure of the aircraft.

1. Bypass turbojet engine comprising a fan casing at the front and an exhaust casing at the rear, said turbojet engine further comprising a cold-flow channel which extends the fan casing in order to guide the cold flow towards the downstream end of the turbojet engine, said cold-flow channel comprising an annular rear end which is connected to the exhaust casing and on which at least one attachment point is positioned which is capable of transmitting the stresses from the exhaust casing to the structure of an aircraft,
characterised in that a plurality of attachment points is positioned on the circumference of said annular rear end of the cold-flow channel, said plurality of attachment points comprising either two diametrically opposed points on said circumference or at least three points forming a polygon, within which the axis of symmetry of the cold-flow channel passes, and in that the turbojet engine is equipped with a rear-suspension hoop which is attached to said attachment points and is capable of being attached to the structure of the aircraft.
