Abstract
A computer-implemented method of tire maintenance including: receiving data of a plurality of tire gas pressure measurements each measurement having an associated time; analyzing the received data to determine maintenance information, wherein the maintenance information comprises at least one of: an inflation event, a maximum pressure, a minimum pressure and a tire replacement event; and providing an indication based the determined maintenance information.
Claims17
A method of tire maintenance comprising:
- actuating pressure sensors mounted to at least two tires on an aircraft;
- measuring tire gas pressure in the at least two tires using the pressure sensors in response to the actuation of the pressure sensors;
- receiving data regarding the measured tire gas pressures in the at least two tires, wherein the data comprises the plurality of tire gas pressure measurements each measurement having an associated time;
- analyzing the received data to determine maintenance information, wherein the maintenance information comprises at least one of:
- an inflation event, a maximum pressure, a minimum pressure or a tire replacement event;
- wherein the analyzing the received data further includes determining deflation rates for the at least two tires and comparing the deflation rates to identify the deflation rate that is greater than at least one other of the deflation rates,
- wherein the maintenance information further includes information regarding the identified deflation rate, and
- providing aircraft tire maintenance based the determined maintenance information, wherein the aircraft tire maintenance is at least one of adding a gas to at least one of the two tires on the aircraft to reinflate the tire or removal from the aircraft of the at least one of the two tires.

A method of tire maintenance comprising:
- actuating pressure sensor mounted to a tire mounted to an aircraft;
- in response to the actuation of the pressure sensor, measuring tire gas pressure in the tire using the pressure sensor to generate a plurality of tire gas pressure measurements each having an associated time of measurement;
- receiving data representative of the plurality of tire gas pressure measurements and the associated time of measurement;
- analyzing the received data to determine an inflation event by determining an inflation frequency or an interval between consecutive inflation events;
- receiving data comprising a retread count of the tire,
- determining whether there is a correlation between the retread count and the inflation frequency, the interval between consecutive inflation events, tire replacement frequency, or an interval between consecutive tire replacements, and
- providing aircraft tire maintenance based the determined maintenance information and the determined correlation, wherein the aircraft tire maintenance is at least one of adding a gas to at least one of the two tires on the aircraft to reinflate the tire or removal from the aircraft of the at least one of the two tires.

A method of tire maintenance comprising:
- actuating pressure sensors mounted to at least two tires on an aircraft;
- measuring tire gas pressure in the at least two tires the using pressure sensors in response to the actuation of the pressure sensors;
- receiving data representative of the measured tire gas pressures from the at least two tires, wherein the data comprises a plurality of the tire gas pressure measurements and an associated time of each of the tire gas pressure measurements;
- analyzing the received data to determine a plurality of inflation events, to determine deflation rates for each of the at least two tires, and to compare the deflation rates to identify a first deflation rate of the deflation rates that that is greater than the deflation rate of at least one other of the at least two tires;
- determining a minimum pressure between two consecutive inflation events;
- determining tire maintenance information for each of the at least two tires based on comparing the minimum pressure to a predetermined threshold and the first deflation rate;
- and
- providing aircraft tire maintenance based on the tire maintenance information, wherein the aircraft tire maintenance is at least one of adding a gas to at least one of the two tires on the aircraft to reinflate the tire or removal from the aircraft of the at least one of the two tires.
