Systems and methods for detecting landing gear ground loads
First Claim
1. A system for predicting loading of a landing gear comprising:
- a plurality of sensors positioned proximate to the landing gear which yield strain data,wherein the plurality of sensors comprises at least five sensors and the plurality of sensors measures at least five loads comprising a drag load, a side load, a vertical load, a moment drag load, and a moment side load, whereby the strain data may be determined; and
a first processor that receives the strain data from the plurality of sensors and predicts at least one ground load applied to the landing gear based on the strain data,wherein the first processor further predicts a weight and a balance of an aircraft based only on the strain data;
a power supply module that provides power to the plurality of sensors;
data acquisition circuitry that interrogates the plurality of sensors to acquire the strain data therefrom; and
a second processor that instructs the data acquisition circuitry as to the sampling rate and data resolution comprising a bit resolution to be used to interrogate the plurality of sensors,wherein the second processor instructs the data acquisition circuitry to increase the sampling rate and the data acquisition resolution in response to a detected increasing strain.

Abstract
There is provided a system for predicting loading of a landing gear including, a plurality sensors positioned proximate to the landing gear. The plurality of sensors measure strain applied to the landing gear, and each sensor yielding strain data. The system further includes a processor that receives the strain data from the plurality of sensors and predicts at least one ground load based on strain data. There is further provided a method for predicting loading of a landing gear. The method includes powering a plurality of sensors located proximate to a landing gear structure, interrogating the plurality of sensors via data acquisition circuitry to yield strain data, instructing the data acquisition circuitry as to a sampling rate and data resolution to be used for the interrogating, and, finally, processing the strain data to predict a ground load.
