Embodiment Construction

[0033] figure 1 The main elements of an electric thrust reverser in one embodiment of the invention are described in . In this embodiment, the thrust reverser mechanism comprises two doors 4 and 5 arranged on either side of the aircraft engine nacelle (not shown). The two doors 4 and 5 slide along the longitudinal axis of the nacelle (not shown) to expose a second channel for diverting the air blown by the aircraft's engine fans and redirecting it forward in the direction opposite to flight Squirt gas.

[0034] The doors 4 or 5 are respectively actuated by their respective mechanisms 2 or 3, which are substantially identical to each other. exist figure 1 In the embodiment of , the same door 3 actuation mechanism as the door 2 actuation mechanism consists of two cylinders 6 and 7, the rods of which are translatable and connected at one point of door 4 so that when the thrust reverser is actuated The drive rod performs the desired movement. The two cylinders 6 and 7 are sub...

Abstract

Provided are an electric thrust reverser system for an aircraft engine nacelle and an aircraft engine nacelle provided with same. The invention concerns an electric thrust reverser system for an aircraft engine nacelle, comprising at least one mechanism (2 or 3) for actuating a thrust reverser mechanism like a reverser door. The actuating mechanism (2 or 3) comprises first (6) and second (7) drive cylinders. Each cylinder comprises a mechanical connection casing (9), a primary lock (8) and a mobile rod (10) rigidly connected to a point linked to the associated reverser mechanism, like a reverser door. A motorised drive unit (11) is connected mechanically by flexible shafts (12) to the mechanical connection casings (9) of each cylinder (6, 7) of the actuating mechanism (2 or 3) and set in motion under the control of a control unit (1) by means of an electrical connection (16, 17). A tertiary lock (13) is disposed to secure the associated thrust reverser mechanism like a thrust reverser door to a fixed structure of the nacelle.

Description

technical field [0001] The invention relates to an electric thrust reverser system of an aircraft engine nacelle and an aircraft engine nacelle equipped with the electric thrust reverser system. Background technique [0002] In the prior art, a type of thrust reverser is known which operates the thrust reverser mechanism of the thrust reverser by means of an electric motor. [0003] In particular, two types of thrust reverser mechanisms are common: a gate-type thrust reverser and a cascade-type thrust reverser. In order to operate these mechanisms, there are known dedicated cylinders that can be driven on command by an electric motor. [0004] In the case of a door-type thrust reverser, a system for locking the doors is provided, comprising control means and locks capable of connecting each door to the fixed structure of the nacelle. When the command to drive the thrust reverser door is issued, its locking system is deactivated by the control part of the thrust reverser do...
