Embodiment Construction

[0077] used to illustrate the invention and in figure 1 The detection device 1 schematically shown in the figure is used to detect at least one oscillation fault in at least one automatic position control chain 2 of at least one control surface (aileron, spoiler, elevator, rudder) 3 of an aircraft, in particular a transport aircraft.

[0078] Usually, this automatic control chain 2 forms part of the electronic flight control system 4 of the aircraft and includes:

[0079] - said control surface 3, which is movable and can be as figure 1 is steered as shown by the double-headed arrow E in , and its position relative to the aircraft structure is set by at least one standard actuator 5;

[0080] - said actuator 5 , which sets the position of said control surface 3 , for example by means of a rod 6 acting on said control surface 3 , according to at least one actuation command received via a link 7 ;

[0081] - At least one sensor 8 , 9 which measures the actual position of said ...

Abstract

The disclosure relates to a method and device (1) for detecting oscillatory failures, an electronic flight control system, and an aircraft. The detection device comprises a first data processing unit (24) configured to determine a first trend of the control surface control order as a function of time, wherein the first trend is defined according to a reference parameter; a second data processing unit (26) configured to determine at least one second trend of the control surface position value as a function of time, wherein the second trend is also defined according to the reference parameter; and a monitoring unit (29) configured to compare the first and second trends in order to verify the existence of a correlation between these first and second trends so as to detect an oscillatory failure as soon as a loss of correlation between the first and second trends appears, if necessary.

Description

technical field [0001] The invention relates to a method and a device for detecting an oscillating fault in at least one automatic position control chain of an aircraft control surface, as well as an electronic flight control system comprising such a detection device. [0002] The present invention is applied to the automatic control chain: [0003] - It is used to automatically control the position of all types of aircraft control surfaces, such as ailerons, spoilers or elevators; [0004] - it forms part of the electronic flight control system of the aircraft; and [0005] - which includes: [0006] · said control surface, which is movable and whose position relative to the aircraft is set by at least one actuator; [0007] · the actuator, which sets the position of the control surface according to at least one received actuation command; [0008] · at least one sensor measuring the actual position of said control surface; and [0009] A computer that generates the cont...
