Abstract

The present disclosure includes a combination sensor and pressure relief valve. The combination sensor and valve may be used with existing aircraft wheel systems. Wheel systems utilizing the combination sensor and valve are also disclosed.

First claim

What is claimed is:

1 . A combination sensor and pressure release valve, comprising:
a housing comprising a stem defining an opening; an over-inflation pressure relief valve within the housing in fluid communication with the opening and comprising a frangible disk configured to rupture at a predetermined pressure; and a tire pressure sensor within the housing in fluid communication with the opening.

2 . The combination sensor and pressure release valve of claim 1 , wherein the stem comprises a threaded pattern configured to mate with a complementary threaded receptacle in a wheel.

3 . The combination sensor and pressure release valve of claim 1 , wherein the predetermined pressure is between about 1400 kPa and about 2000 kPa.

4 . The combination sensor and pressure release valve of claim 3 , wherein the predetermined pressure is about 1700 kPa.

5 . The combination sensor and pressure release valve of claim 1 , wherein the tire pressure sensor is powered and interrogated by an external magnetic field.

6 . The combination sensor and pressure release valve of claim 1 , wherein the housing comprises a metal.

7 . The combination sensor and pressure release valve of claim 1 , wherein the housing is manufactured by an additive process.

8 . An aircraft wheel system, comprising:
a wheel having a sensor receptacle; and a combination pressure sensor and pressure relief valve comprising a housing having a stem and an opening, an over-inflation pressure relief valve within the housing in fluid communication with the opening comprising a frangible disk configured to rupture at a predetermined pressure, and a tire pressure sensor within the housing in fluid communication with the opening.

9 . The aircraft wheel system of claim 8 , wherein the stem comprises a threaded pattern configured to mate with a complementary threaded pattern of the sensor receptacle in the wheel.

10 . The aircraft wheel system of claim 8 , wherein the housing is manufactured by an additive process.

11 . The aircraft wheel system of claim 8 , wherein the tire pressure sensor is powered and interrogated by an external magnetic field.

12 . The aircraft wheel system of claim 11 , further comprising a sensor reading device configured to power and to interrogate the tire pressure sensor and receive a pressure datum from the tire pressure sensor.

13 . The aircraft wheel system of claim 12 , further comprising an interface, wherein the sensor reading device transmits the pressure datum to the interface.

14 . The aircraft wheel system of claim 8 , wherein the predetermined pressure is between about 1400 kPa and about 2000 kPa.

15 . The aircraft wheel system of claim 14 , wherein the predetermined pressure is about 1700 kPa.
