Aircraft Prognostics Health System
First Claim
1. A method of assessing use of an aircraft component installed on an aircraft, comprising:
- receiving, from one or more sensors installed on the aircraft, one or more measurements representative of at least one load applied against the aircraft component;
selecting at least one usage model from a plurality of usage models, each usage model of the plurality of usage models relating aircraft loads with received sensor data;
determining at least one load value based on the selected at least one usage model and the received one or more measurements; and
calculating, based on the determined at least one load value, an amount of change in probability of failure caused by application of the at least one load against the aircraft component.

Abstract
According to one example embodiment, a method of assessing use of an aircraft component installed on an aircraft includes receiving, from one or more sensors installed on the aircraft, one or more measurements representative of at least one load applied against the aircraft component; selecting at least one usage model from a plurality of usage models, each usage model of the plurality of usage models relating aircraft loads with received sensor data; determining at least one load value based on the selected at least one usage model and the received one or more measurements; and calculating, based on the determined at least one load value, an amount of change in probability of failure caused by application of the at least one load against the aircraft component.

10. A system for assessing use of a rotorcraft component installed on a rotorcraft, comprising:
-
a rotorcraft comprising a rotorcraft component, a body, a power train coupled to the body and comprising a power source and a drive shaft coupled to the power source, a hub, a rotor blade coupled to the hub, and one or more sensors operable to provide a plurality of measurements; and a prognostics health system installed onboard the rotorcraft and operable to; receive, from one or more sensors installed on the rotorcraft, one or more measurements representative of at least one load applied against the rotorcraft component; select at least one usage model from a plurality of usage models, each usage model of the plurality of usage models relating rotorcraft loads with received sensor data; determine at least one load value based on the selected at least one usage model and the received one or more measurements; and calculate, based on the determined at least one load value, an amount of change in probability of failure caused by application of the at least one load against the rotorcraft component. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
