Definitions
- the invention relates to the field of aircraft braking and relates more particularly to an improved method of aircraft braking.
- the braking system comprising the brakes of wheels 10
- the thrust reverser system comprising the thrust reversers 12.
- the wheel brakes 10 are controlled from a wheel braking controller 14 which receives a request for deceleration regulation 16 from the cockpit 18 and issues an order deceleration regulation 20 for the wheel brakes 10.
- the thrust reversers 12 are for their part controlled from a thrust reverser controller 22 which receives a request for deployment of the thrust reversers 24 from the cockpit 18 from where from the actions of the pilot 26 and issues an order to deploy the thrust reversers 28 for the thrust reversers 12.
- One of the main functions of the wheel braking system is to provide deceleration regulation (“autobrake” function) allowing the airplane to decelerate homogeneously (smoothly) and adapted to the runway and the terrain. output (“brake to vacate” function).
- the request for deployment of the thrust reversers is received either directly by the wheel braking controller from an aircraft cockpit, or directly by the wheel braking controller and relayed to a reverser controller.
- thrust reverser actuating the deployment of the thrust reversers, or either directly by a thrust reverser controller which relays it to the wheel braking controller.
- FIG. 1 shows a simplified architecture of the wheel braking and thrust reversal systems according to a first embodiment of the invention
- FIG. 6 shows wheel braking and thrust reversal systems according to a conventional simplified architecture of the prior art
- FIG. 7 Figure 7 illustrates the deceleration curve of the wheel braking system of Figure 6.
- FIGS. 1 to 3 Three embodiments of the invention illustrated successively in FIGS. 1 to 3 are envisaged to provide this information to the wheel braking controller.
- the deceleration profile is however not optimal because the wheel braking controller cannot control the moment when the thrust reversers will deploy and it therefore does not know their real state. He can only react in relation to the deployment request made by the pilot and estimate that the deployment is actually taking place. Consequently, there is a risk of taking into account the order of deployment of the inverters when they are not deployed, causing a transient very harmful to comfort and braking performance (with an effective deceleration lower than the one ordered). This risk can however be eliminated by providing for the receipt of information 30 from the thrust reverser controller on this real state of the reversers allowing it to verify that the reversers are properly deployed.
- this architecture allows very simply, in a degraded mode in which the deployment request is not taken into account, a return to the conventional architecture where the braking of the wheels and the deployment of the thrust reversers are managed independently. 'from each other.
- the thrust reverser controller 22 relay the request for deployment of the thrust reversers 24 received directly from the cockpit 18 to the wheel brake controller 14.
- the deceleration profile is not optimal either because the wheel braking controller cannot control the moment when the thrust reversers are going to deploy and it therefore does not know their real state. It can only react in relation to the deployment request received from the thrust reverser controller and estimate that the deployment is actually taking place. Consequently, there is a risk of taking into account the order of deployment of the reversers when the latter are not deployed, causing a transient which is very detrimental to comfort and to braking performance. However, as previously, this risk can be eliminated by providing for the receipt of information 30 from the thrust reverser controller on this actual state of the reversers allowing it to verify that the reversers are indeed deployed.
- This architecture also allows very simply a return to the classic architecture where the braking of the wheels and the deployment of the thrust reversers are managed independently of one another by choosing in a degraded mode not to take into account the demand for deployment and the possible state of the inverters.
- the deceleration regulation request 16 and the request for deployment of the thrust reversers 24 are both addressed to the wheel braking controller 14 which can then choose to relay the request for deployment of the reversers. thrust to the thrust reverser controller 22 for example only when it is ready to take its effect into account. Once this request has been relayed to the thrust reverser controller 22, the latter can confirm proper reception to the wheel braking controller and send it information 30 on the actual state of the thrust reversers: reverser not deployed, in deployment , deployed.
- This master (for the brakes) slave (for the inverters) type operation makes it possible to optimize the deceleration of the aircraft as much as possible because the deceleration regulation algorithm can be perfectly adapted from the real state of the inverters. It is also possible to recreate (by an inverse model which returns by example the instantaneous or predicted deceleration delta with a certain advance to the wheel braking controller) the deceleration induced by the thrust reversers and integrate it directly into the deceleration regulation in order to be able to easily reject the disturbance due to the deployment thrust reversers. This can be done in the thrust reverser controller or in the wheel brake controller subject to sharing of model data necessary for regulation.
- FIG. 4 illustrates an exemplary embodiment of the wheel braking controller 14 which delivers the deceleration regulation order 20 for the wheel brakes 10 from the deceleration regulation request 16.
- This controller comprises a corrector 32 which acts. as is known on a regulation deviation between a setpoint 34 and a measured value of this deceleration 21.
- this setpoint is not a nominal deceleration setpoint 36 but a suitable deceleration setpoint delivered by an adaptation module of the setpoint 38 which receives the request for deployment of the thrust reversers 24 and possibly the information 30 on the actual state of these thrust reversers 12.
- This module 38 therefore makes it possible to switch from the nominal deceleration setpoint to the adapted deceleration setpoint .
- the wheel braking controller can thus directly modify its deceleration setpoint in line with the request for deployment of the thrust reversers so that the braking effect of the reversers and the wheel braking setpoint coincide with the value requested in the cockpit. from the plane.
- the deceleration setpoint returns to the constant value of the nominal setpoint 36 so as not to accelerate too much and have a minimum of oscillations during the transients.
- adaptation can have the same result as the aforementioned setpoint adaptation.
- an adaptation of the gain of the transfer function of the closed loop system is also possible.
- the gains of the regulation loop are modified at the time of the events defined by the request for deployment of the thrust reversers and the state of these thrust reversers.
