Abstract

An ignition testing system including a test article testing chamber, and at least one gas mixture verification chamber being communicably coupled to the test article testing chamber and being configured to verify at least a content of a gas mixture content provided to the test article testing chamber.

First claim

What is claimed is:

1. An ignition testing system comprising:
a test article testing chamber; and
at least one gas mixture verification chamber having a sealed interior being communicably coupled to the test article testing chamber so that a common gas mixture content is shared by both the test article testing chamber and the at least one gas mixture verification chamber, and the at least one gas mixture verification chamber being configured to selectively seal the sealed interior of the at least one gas mixture verification chamber from the test article testing chamber and further configured to verify within the selectively sealed interior of the at least one gas mixture verification chamber at least an incendivity of the common gas mixture content provided to the test article testing chamber.

2. The ignition testing system of claim 1 , wherein the at least one gas mixture verification chamber comprises:
a chamber frame forming the sealed interior, where the chamber frame includes at least one aperture; and
a transparent member configured to seal the at least one aperture.

3. The ignition testing system of claim 1 , further comprising a voltage arc source disposed within the sealed interior of the at least one gas mixture verification chamber.

4. The ignition testing system of claim 1 , further comprising a pressure sensor, where the at least one gas mixture verification chamber includes a chamber frame forming the sealed interior and having at least one sensor port in communication with the sealed interior of the chamber frame, the pressure sensor being coupled to the at least one sensor port.

5. The ignition testing system of claim 1 , further comprising a thermocouple, where the at least one gas mixture verification chamber includes a chamber frame forming the sealed interior and having at least one sensor port in communication with the sealed interior of the chamber frame, the thermocouple being coupled to the at least one sensor port.

6. The ignition testing system of claim 1 , further comprising:
a gas mixture inlet in communication with the sealed interior of the at least one gas mixture verification chamber;
a gas mixture outlet in communication with the sealed interior of the at least one gas mixture verification chamber;
a first valve coupled to the gas mixture inlet, the first valve being configured to seal the gas mixture inlet; and
a second valve coupled to the gas mixture outlet, the second valve being configured to seal the gas mixture outlet.

7. The ignition testing system of claim 6 , wherein the test article testing chamber is removably coupled to one of the gas mixture inlet and the gas mixture outlet through a respective one of the first valve and the second valve.

8. The ignition testing system of claim 6 , further comprising a lock out module coupled to the first valve and the second valve, the lock out module being configured to prevent operation of the at least one gas mixture verification chamber depending on an operational position of the first valve and the second valve.

9. The ignition testing system of claim 6 , further comprising a voltage arc source disposed within the sealed interior of the at least one gas mixture verification chamber, the voltage arc source being disposed between the gas mixture inlet and the gas mixture outlet so as to generate turbulent gas flow through the sealed interior.

10. An ignition testing system comprising:
a test article testing chamber;
a first gas mixture verification chamber being communicably coupled to the test article testing chamber to provide a gas mixture to the test article testing chamber;
a second gas mixture verification chamber being communicably coupled to the test article testing chamber to receive the gas mixture from the test article testing chamber; and
wherein:
first gas mixture verification chamber and the second gas mixture verification chamber are coupled to each other through the test article testing chamber to form a common environment that is common to an interior of each of the first gas mixture verification chamber, the second gas mixture verification chamber, and the test article chamber, and
the interior of the first gas mixture verification chamber and the interior of the second gas mixture verification chamber each being selectively sealed from the interior of the test article testing chamber to verify within the respective selectively sealed interior of the first gas mixture verification chamber and the second gas mixture verification chamber at least an incendivity of the gas mixture within the test article testing chamber.

11. The ignition testing system of claim 10 , further comprising a pressure relief in communication with a sealed interior of each of the first gas mixture verification chamber and the second gas mixture verification chamber.

12. The ignition testing system of claim 10 , wherein each of the first gas mixture verification chamber and the second gas mixture verification chamber further comprise a purge gas inlet in communication with a respective sealed interior of the first gas mixture verification chamber and the second gas mixture verification chamber.

13. The ignition testing system of claim 10 , further comprising a pulser disposed adjacent the test article testing chamber.

14. The ignition testing system of claim 10 , further comprising a controller coupled to one or more of the test article testing chamber, the first gas mixture verification chamber, and the second gas mixture verification chamber, the controller being configured to effect operation of the ignition testing system.

15. The ignition testing system of claim 10 , wherein one or more of the test article testing chamber, the first gas mixture verification chamber, and the second gas mixture verification chamber includes at least one of a heater, a cooler, a humidifier, and a dehumidifier.

16. A method for ignition testing with an ignition testing system, the method comprising:
filling an interior volume of a test article testing chamber and at least one gas mixture verification chamber with a gas mixture, where the test article testing chamber is communicably coupled to the at least one gas mixture verification chamber so that the gas mixture flows from one of the test article testing chamber and the at least one gas mixture verification chamber to another one of the test article testing chamber and the at least one gas mixture verification chamber;
sealing the interior volume of each of the test article testing chamber and the at least one gas mixture verification chamber from the interior volume of each other one of the test article testing chamber and the at least one gas mixture verification chamber; and
validating, with the at least one gas mixture verification chamber, a test environment within the test article testing chamber;
wherein validating the test environment within the test article testing chamber comprises verifying an incendivity of the gas mixture within the at least one gas mixture verification chamber.

17. The method of claim 16 , wherein filling the interior volume of the test article testing chamber and at least one gas mixture verification chamber with the gas mixture comprises purging the interior volume of the test article testing chamber and at least one gas mixture verification chamber with an inert gas.

18. The method of claim 16 , wherein filling the interior volume of the test article testing chamber and at least one gas mixture verification chamber with the gas mixture comprises drying the interior volume of the test article testing
