1. A system for determining a force applied to an outer disc of an aircraft brake by an actuator, the system comprising:
- a current sensor coupled to the actuator and configured to detect a detected amount of current applied to the actuator; and
a controller coupled to the current sensor and configured to determine an estimate of the force applied to the outer disc based on the detected amount of current and a plurality of predetermined input parameters.

Abstract
What is described is a system for determining a force applied to an outer disc of an aircraft brake by an actuator motor. The system includes a current sensor coupled to the actuator motor and configured to detect an amount of current applied to the actuator motor. The system also includes a controller coupled to the current sensor. The controller is configured to determine an estimate of the force applied to the outer disc based on the detected amount of current and predetermined input parameters.

11. A method for determining a force applied to an outer disc of an aircraft brake by an actuator, the method comprising:
-
receiving, at a controller and by a current sensor, a detected amount of current applied to the actuator; receiving, at the controller, the detected amount of current and input parameters including a maximum force of the actuator, a maximum current of the actuator and an efficiency fraction of the actuator; determining, by the processor, a mode of operation of the actuator including a first mode indicating that the force applied to the outer disc increases proportionally as the amount of current applied to the actuator increases, a second mode indicating that the force applied to the outer disc remains substantially constant as the amount of current applied to the actuator decreases a first amount and a third mode indicating that the force applied to the outer disc decreases proportionally as the amount of current applied to the actuator decreases a second amount; and determining, by the processor, an estimated amount of force applied to the outer disc of the aircraft brake by the actuator based on the input parameters and the detected amount of current. - View Dependent Claims (12, 13, 14, 15)
