Definitions
- the present invention relates to a door for thrust reverser doors and such a thrust reverser and a nacelle equipped with such a thrust reverser.
- the role of a thrust reverser during the landing of an aircraft is to improve the braking capacity of an aircraft by redirecting forward at least a portion of the thrust generated by the turbojet engine.
- the inverter obstructs the gas ejection nozzle and directs the ejection flow of the engine towards the front of the nacelle, thereby generating a counter-thrust which is added to the braking of the wheels of the engine. the plane.
- the means implemented to achieve this reorientation of the flow vary according to the type of inverter.
- the structure of an inverter comprises movable covers moved between, on the one hand, an extended position in which they open in the nacelle a passage intended for the deflected flow, and on the other hand, a retracted position in which they close. this passage.
- These mobile hoods may furthermore perform a deflection function or simply the activation of other deflection means.
- the movable hoods slide along rails so that when backing up during the opening phase, they discover deflection vane grids arranged in the thickness of the nacelle .
- a linkage system connects the movable hood to blocking doors that expand within the ejection channel and block the output in direct flow.
- a door-thrust reversal device comprises one or more doors pivotally mounted so as to be able, under the action of drive means, to switch between an inactive position called closure during operation of the so-called turbojet engine.
- the doors constitute a part of the downstream section, and an inverting position or opening position in which they swing in such a way that a downstream part of each door comes to obstruct at least partially the duct of the nacelle and an upstream portion opens in the downstream section a passage allowing the flow of air to be channeled radially relative to a longitudinal axis of the nacelle.
- the pivot angle of the doors is adjusted so as to greatly reduce or eliminate the thrust force generated by the flow escaping in direct jet and up to possibly generate a counter-thrust by generating a component of the deflected flow upstream of the nacelle.
- the doors In order to be able to improve the reorientation of the air flow in a direction tending as close as possible to a longitudinal direction of the nacelle, the doors have been equipped with deflection means, generally constituted by terminal spoilers, also called deflectors, forming upstream of the door a return substantially perpendicular to the latter.
- deflection means generally constituted by terminal spoilers, also called deflectors, forming upstream of the door a return substantially perpendicular to the latter.
- the spoiler when the door is in the reverse thrust position, the spoiler is oriented in a substantially longitudinal direction of the nacelle and forces the flow of air in this direction.
- each spoiler Conversely, when the door is in the closed position, each spoiler is oriented in a direction substantially perpendicular to the longitudinal axis of the nacelle. Each spoiler then enters the flow of the flow of air stream and may then block the flow of air flowing in the nacelle direct jet, which is not permissible.
- the doors have been designed to have an upstream cavity at an inner surface of said door. Therefore, the door has upstream a reduced thickness which allows both the spoiler to project from said door and not to have a length greater than the thickness of the nacelle upstream of the door so as not to enter the flow vein of the airflow when the door is in the closed position.
- a general inverter gate structure is shown in FIGS. 1 and 2 in respectively closed and open positions. It should be noted, however, that such a cavity is a major aerodynamic accident inside the air flow duct when the door is in the closed position, which reduces the overall performance of the turbojet engine.
- a drawback related to this achievement lies in the reliability of the actuating system of the door spoiler, not proving sufficiently strong compared to the forces developed by the spoiler when it opens.
- the deflection means are subjected to significant forces that can lead to tearing of the deflection means when the latter are in the deployed position, that is to say for a door open position.
- the present invention aims at improving the direct jet and reverse jet performance of the thrust reverser with doors, by proposing a door for thrust reverser with doors, whose deflection means do not deform under load and do not vibrate. when using the low frequency turbojet engine, and whose actuating systems such spoilers are strong enough to withstand the forces generated by the spoilers when they open.

- said resilient means being adapted to open the angle formed by said second and third connecting rods.
- the actuating means according to the invention are shaped to withstand the forces suffered by the deflection means when they open and allow said deflection means to be maintained in a position in which they ensure optimum reorientation of the flow passing through the vein and blocked. through the door.
- the actuating means according to the invention comprise a set of three connecting rods connected to elastic means, which constitutes a relatively easy system to assemble and limited in number of parts necessary for the deployment and retraction of the deflection means , which makes it possible to reduce the mass of the assembly constituted by the deflection means and by its actuating means.

- the elastic means are contained integrally inside the deflection means when the door is in the closed position.
- the elastic means comprise a tension or compression spring.
