Problems solved by technology

[0018] This architecture of the aircraft control system has some disadvantages, among them: the increase in the number of sensors and the associated increase in the wiring, which increases the burden on the weight plan of the aircraft
In addition, the analog signals transmitted by these sensors may be affected by noise caused by electromagnetic interference

Embodiment Construction

[0046] Consider again an aircraft control system that includes multiple meta-control systems, each meta-control system responsible for a specific function of the aircraft. These meta-control systems can be, for example, those mentioned in the introduction.

[0047] The basic idea of ​​the invention is to extend the AFDX network, which usually connects the computers of the avionics cabinet, to the entire flight control system, so that the computers, sensors and actuators of the system are connected to this network. In this way, any two meta-control systems connected to the same AFDX network can share one or more sensors.

[0048] image 3 The architecture of an aircraft control system according to an embodiment of the present invention is schematically shown. For purposes of simplification and not limitation, only two meta-control systems SC are shown 1 and SC 2 . Meta Control System SC 1 includes at least one computer 310 each connected to an AFDX network 340 1 and a pl...

Abstract

The invention relates to an aircraft control system in which a plurality of elementary control systems, corresponding to different aircraft functions, can share one or more sensors due to a common AFDX network. The transmission of commands is carried out via AFDX messages sent to network-subscribed actuators. Advantageously, the computers of the different elementary control systems installed in the avionics bay consist of generic computers hosting software specific to the execution of the respective functions thereof (IMA architecture).

Description

technical field [0001] The present invention generally relates to aircraft control systems. Background technique [0002] The control of an aircraft usually requires numerous control systems, in particular: [0003] - the primary flight control system, which allows the control of the aircraft around its roll, side Movement of the yaw and pitch axes. It also controls the traction of the aircraft by acting on the air brakes (spoilers); [0004] - the secondary flight control system which allows the control of the wing camber during take-off and landing phases by acting on the trailing and leading edge flaps (also called wing leading edges (slats)), thereby controlling the lift; [0005] - propulsion control system, which allows to control and reverse the thrust of the motor; [0006] - Landing gear braking control system; [0007] - steering control system; [0008] -Hydraulic line control system. [0009] The primary flight control system is often referred to simply a...
