Abstract

Method and device for implementing the thrust reversers of an aircraft. According to the invention, the following successive steps are carried out automatically: deployment (E3) of the previously armed thrust reversers of the aircraft; application (E5) of a predetermined engine speed; reduction (E6) of the engine speed; - re-furling (E7) of the thrust reversers of the aircraft.

Description

technical field

[0001] The invention relates to a method and a device allowing the use of a thrust reverser of an aircraft, as well as an aircraft comprising such a device. Background technique

[0002] It is known that civil aircraft equipped with turbojet engines are provided with thrust reversers which allow improved braking of the aircraft by reducing the glide distance on the ground in particular when landing and take-off are interrupted. Thrust reversers are associated with the engines of the aircraft and are controllable so as to be able to pass from an inoperative stowed position to an operative deployed position and conversely from said operative deployed position to said inoperative Put away the location. After adjusting the speed of rotation of the engines, the pilot can manually initiate the deployment of the thrust reversers associated with these engines by means of controls of the joystick type.

[0003] However, the thrust reversers run the risk of untimely ...

Embodiment Construction

[0058] Although in the following embodiments according to the present invention, the aircraft is a twin-engine aircraft equipped with a thrust reverser, it is easy to understand that the system of the present invention can also be installed on an aircraft equipped with an engine tail nozzle section changing device. on the thrust reverser.

[0059] The speed of each engine is individually controlled between idle and full speed by a throttle lever respectively associated with said engine and actuated by the pilot.

[0060]In a preferred embodiment, the thrust reverser is controlled by means of a single control element 1, described below Figures 4A to 4D Embodiments of the control element in different positions are schematically shown in .

[0061] Such as figure 1 As shown, the automatic use of the thrust reverser according to the invention (referred to as automatic mode) is as follows.

[0062] Assume initially that the aircraft is in a phase approaching the runway, and in ...
