Non-contact infrared temperature sensor for health monitoring of rotorcraft bearings
First Claim
1. A method for measuring a temperature of one or more bearings associated with a rotor assembly of a craft comprising:
- attaching one or more non-contact temperature sensors on the craft to measure a change in temperature in the one or more bearings; and
connecting the one or more non-contact temperature sensors to a computer;
receiving a temperature signal from the one or more non-contact temperature sensors; and
monitoring the temperature, stress, or both, of the one or more bearings in real-time before, during, or after craft operations using the computer and the one or more non-contact temperature sensors.

Abstract
The present invention includes an apparatus and method for measuring hysteretic heating or stress of one or more bearings of a craft comprising: one or more non-contact temperature sensors attached to the craft and directed toward the one or more bearings; and a computer connected to the one or more non-contact temperature sensors that measure the temperature, the stress, or both of the one or more bearings before, during, or after operation of the craft, wherein the one or more non-contact temperature sensors measure a change in temperature in the one or more bearings to monitor for heating or stress of the bearings.
