AI Technical Summary

Problems solved by technology

The temperature sensor is indirectly coupled to the gas in the tire, so it cannot be assumed that the measured temperature is the same as the temperature of the gas in the tire
Additionally, the relationship between gas temperature and temperature sensors is complex, influenced by factors such as the time of heat transfer through the wheels and external heat sources such as cooled brake discs and current weather conditions

Embodiment Construction

[0032] It has been found that if a historical record of tire pressure measurements and temperature measurements is kept, the historical data can be used to increase the reliability of tire pressure measurements and enable improved tire maintenance.

[0033] With the advent of automatic electronic tire monitoring devices affixed to aircraft wheels, tire pressures can be periodically measured to obtain historical pressure data without the need for the operator to enter and store with associated measurement times or timestamps. When the tire monitoring device also includes a temperature sensor, temperature data may also be stored together with pressure data. Thus, a history of pressure / temperature pairs with associated time stamps can be built up over time.

[0034] Both pressure and temperature vary depending on the operation of the aircraft, including the length of the flight, turnaround time, ambient temperature at the destination, and weather at the destination. As noted abo...

Abstract

A computer-implemented method of determining tire pressure is provided. The method includes: receiving data including a latest stable point of tire gas pressure and temperature; receiving data of a desired temperature at which a current pressure is desired to be determined; and determining the current pressure from the data of the latest stable point and the desired temperature.

Description

technical field [0001] The invention relates to a method and a device for determining tire gas pressure and tire gas temperature. Background technique [0002] The monitoring of tire inflation pressure is an important part of aircraft maintenance. Underinflated tires are more likely to burst during takeoff and / or landing, and tire bursts can cause severe damage to surrounding aircraft structures. Therefore, periodic tire pressure checks on commercial aircraft are mandatory. [0003] Current methods of tire pressure checking include manual methods (using a pressure gauge to measure each individual tire) and automatic methods (interrogating a pressure sensor attached to each wheel to measure the associated tire pressure). Regardless of whether the pressure check is manual or automatic, tire pressure maintenance decisions are based on readings from all tires taken in a single measurement session. For example, by manual measurement, each tire pressure is measured and recorded...
