Abstract

Tire pressure monitoring systems and methods for detecting a tire burst are disclosed. The system may include a tire pressure sensor, a tire pressure monitor, and a tire burst indicator. The tire pressure sensor may measure tire pressure in an aircraft tire. The tire pressure monitor may analyze data from the tire pressure sensor to detect a tire burst. A tire burst may be detected in response to a rapid decrease in tire pressure. In response to detecting a tire burst, the tire pressure monitor may transmit a tire burst message to the tire burst indicator. The tire burst indicator may indicate to a pilot that a tire burst has been detected.

Claims

1. A system for detecting a tire burst comprising:

a tire pressure sensor;

a tire pressure monitor for registering the tire burst in response to a decrease in tire pressure measured by the tire pressure sensor; and

a binary tire burst indicator which indicates the tire burst in response to the tire pressure monitor registering the tire burst, wherein the binary tire burst indicator is configured to prevent indication of a low-pressure tire.

2. The system of claim 1, wherein the binary tire burst indicator indicates which tire has burst.

3. The system of claim 1, wherein the tire pressure monitor registers the tire burst in response to the tire pressure decreasing by greater than 50% within 50 milliseconds.

4. The system of claim 1, wherein the tire pressure monitor registers the tire burst in response to detecting a rate of decrease of the tire pressure of at least 1,000 psi per second.

5. The system of claim 1, wherein the tire pressure monitor identifies a tire pressure leak.

6. The system of claim 1, wherein the binary tire pressure sensor is coupled to an aircraft tire.

7. A method comprising:

measuring a tire pressure with a tire pressure sensor;

determining, by as processor and in response to a decrease in the tire pressure, that a tire burst has occurred; and

indicating, with a binary tire burst indicator, that the tire burst has occurred, wherein the binary tire burst indicator is configured to prevent indication of a low-pressure tire.

8. The method of claim 7, wherein the tire pressure decreases by a rate of at least 1,000 psi per second.

9. The method of claim 7, further comprising transmitting, by the tire pressure monitor, a tire burst message to the binary tire burst indicator.

10. The method of claim 7, wherein the tire pressure monitor determines that the tire burst has occurred in response to at least one of a detecting a decrease of at least 50% of the tire pressure within 50 milliseconds and a decrease of at least 90% of the tire pressure within 200 milliseconds.

11. The method of claim 7, wherein the binary tire burst indicator indicates the tire burst to a pilot during takeoff.

12. The method of claim 7, further comprising identifying, by the tire pressure monitor, a leak.

13. An article of manufacture including a tangible, non-transitory computer-readable storage medium having instructions stored thereon that, in response to execution by a computer-based system for detecting a tire burst, cause the computer-based system to perform operations comprising:

measuring, by the computer-based system, a tire pressure with a tire pressure sensor;

determining, by the computer-based system and in response to a decrease in the tire pressure, that a tire burst has occurred; and

indicating, by the computer-based system and with a binary tire burst indicator, that the tire burst has occurred, wherein the binary tire burst indicator is configured to prevent indication of a low-pressure tire.

14. The article of manufacture of claim 13, wherein the tire pressure decreases by a rate of at least 1,000 psi per second.

15. The article of manufacture of claim 13, the operations further comprising transmitting, by the computer-based system, a tire burst message to the binary tire burst indicator.

16. The method of claim 13, wherein the computer-based system determines that the tire burst has occurred in response to at least one of a detecting a decrease of at least 50% of the tire pressure within 50 milliseconds and a decrease of at least 90% of the tire pressure within 200 milliseconds.

17. The method of claim 13, wherein the binary tire burst indicator indicates the tire burst to a pilot during takeoff.
