Abstract

It is described a movable pylon, associated with a lower portion of aircraft wing and with an aircraft engine to change the height of this engine between a flying position and a ground position, the movable pylon comprising: a main unique structure formed by a first movable structure pivoted to a second fixed structure, the first movable structure associated with the engine, the second fixed structure associated with the wing, and a pivot mechanism connecting the first movable structure to at least one point on the wing.

Claims

1. Movable pylon, associated with a lower portion of aircraft wing and with an aircraft engine to change the height of this engine between a flying position and a ground position, characterized in that it comprises:

a main unique structure formed by a first movable structure pivoted to a second fixed structure,

the first movable structure associated with the engine,

the second fixed structure associated with the wing, and

a pivot mechanism connecting the first movable structure to at least one point on the wing.

2. Pylon, according to claim 1, wherein the pivot mechanism is provided with a pair of sets of pivoted bars parallel to each other, comprising first edges associated with the point on the wing and second edges associated with the first movable structure.

3. Pylon, according to claim 2, wherein the pivot mechanism further comprises at least a hydraulic or electric actuator arranged next to the first movable structure and displacing the pair of sets of pivoted bars.

4. Pylon, according to claim 2, wherein the pivot mechanism further comprise at least a hydraulic or electric actuator arranged next to the second fixed structure and displacing the pair of sets of pivoted bars.

5. Pylon, according to claim 3, wherein the hydraulic or electric actuator and the pivot mechanism displace the first movable structure changing the height of the engine between a flying position to a ground position.

6. Movable pylon, associated with a lower portion of an aircraft wing and with an aircraft engine to change the height of this engine between a flying position and a ground position, characterized in that it comprises:

A main unique structure associated with the lower portion of the wing by means of at least one pivoting point and at least one pivot mechanism.

7. Pylon, according to claim 6, wherein the pivot mechanism comprises a set of pivoted bars associated with the lower portion of the wing and displaced by means of a hydraulic or electric actuator.

8. Pylon, according to claim 7, wherein the displacement of pivoted bar results in the change of engine height between a flying position and a ground position.
