Problems solved by technology

[0017] However, a common disadvantage of these solutions is that they only solve one side of the problem, namely, either ensuring sufficient airflow diversion for the thrust reverser to perform its function effectively, or sufficient airflow exhaust to avoid damage to the turbine Jet Engine Requirements
[0018] Furthermore, prior art devices are complex to implement, or are not suitable for the problems inherent in the aviation sector, which is the constant quest to reduce weight

Embodiment Construction

[0042] Typically and well known, a thrust reverser comprises at least one door adapted to be driven by an actuator or the like, the door being moved from a "closed door" position corresponding to the engine compartment operating in direct injection mode to a position corresponding to the engine compartment The "door open" position where the cabin operates in reverse injection mode.

[0043] see figure 1 , showing a nacelle 1 of a turbojet engine 3 operating in reverse injection mode, a portal thrust reverser according to the invention comprising two doors 5a, 5b according to the invention.

[0044] The doors 5a and 5b are identical, and one of them is referred to as door 5 in the following description.

[0045] The door 5 according to the invention is constructed in such a way that the inner wall 7 is connected to the outer wall 9 by a side wall 11 and according to the invention the door 5 comprises a deflection device 13 .

[0046]For the direct injection mode of the nacell...

Abstract

The present invention relates to a thrust reverser having gates. Said gate includes an inner wall (7), which is part of a flow path (V) of an airflow (F) generated by a turbojet engine, an outer wall (9), at least one sidewall (11), and a means for deflecting the airflow (F) generated by the turbojet engine. The gate according to the invention is characterized in that the deflecting means includes a cavity of the gate, said cavity being shaped so as to convey at least a fraction of said airflow (F) from an air intake (17) rigidly connected to the inner wall (7) of the gate to an air outlet (19) rigidly connected to the sidewall (11) of the gate, such that, when the nacelle is operating in a reverse-jet mode, at least a portion of said airflow is redirected upstream from the inner wall (7) of the gate.

Description

technical field [0001] The invention relates to a door for a thrust reverser of the portal type, as well as such a thrust reverser and a nacelle equipped with such a thrust reverser. Background technique [0002] The function of the thrust reverser device when the aircraft is landing is to turn at least a part of the thrust produced by the turbojet engine to the front, so as to improve the braking ability of the aircraft. During this phase, the thrust reverser blocks the gas nozzles and directs the jet stream from the engine towards the front of the nacelle, which creates reverse thrust that adds to the braking of the aircraft's wheels. [0003] The means used to achieve this airflow diversion vary depending on the type of thrust reverser. In all cases, however, the structure of the thrust reversers consists of movable cowls movable between a deployed position in which they open a passage in the nacelle for the diverted airflow and a retracted position in which In the retr...
