Abstract
The present disclosure relates to brake control and monitoring, and more particularly, to a brake control and monitoring system that monitors brake actuation force.
Claims11
An aircraft brake control and monitoring system, comprising:
- a control and sense wire harness;
- a load cell disposed in a load path between a plurality of motors and a main landing gear brake stack, wherein the load cell is configured to provide a measured actuation force signal representative of a force exerted by the plurality of motors on the main landing gear brake stack to the control and sense wire harness;
- a junction box configured to selectably connect the control and sense wire harness to a brake actuator and the plurality of motors, wherein the measured actuation force signal may be received and logged by a method of brake actuation force logging;
- a force sensor system comprising a plurality of force sensors in mechanical communication with a plurality of brakes the plurality of brakes including the main landing gear break stack;
- and
- a processor configured to receive force measurements of each of the plurality of brakes from the plurality of force sensors, the force measurements defined as a force data set, calculate a single force data centrality value based on the force data set, calculate a force deviation value for each of the plurality of brakes based on the relative forces measured for each of the plurality of brakes compared to the single force data centrality value, and assign a health status for each of the plurality of brakes.

An aircraft brake control and monitoring system comprising:
- an electrical brake actuation controller;
- a first aircraft brake actuator connected to the electrical brake actuation controller and controllable by the electrical brake actuation controller;
- a first braking unit connected to the first aircraft brake actuator, the first braking unit comprising a first plurality of motors and a first brake stack;
- a first load cell disposed in a first load path between the first plurality of motors and the first brake stack, the first load cell configured to provide a first measured actuation force signal representative of a first braking force applied to the first brake stack;
- and
- a processor configured to receive the first measured actuation force signal, calculate a force data centrality value based on the first measured actuation signal and at least one other force actuation signal received from one of a plurality of brakes, calculate a force deviation value for each of the plurality of brakes based on the relative forces measured from each of the plurality of brakes compared to the force data centrality value, and assigns a health status for each of the plurality of brakes.
