The Birth of FACE- Test #1
This is the first ever practical test of F.A.C.E. - Fire Activated Canister Extinguisher, using solid retardant with an aerosol-like dispersion. This test allowed me to determine that the height of the canister needed to be lower relative to a fire in order to achieve sufficient contact for supression.
Baby Steps- Test #2
Building off of the information from the first test, where the retardant was propelled a very limited distance, I changed my experimental setup to mount FACE closer to the ground in a more open environment. This test allowed me to determine that a switch from a solid-based retardant to a liquid one would be the best option for consistent dispersion and suppression.
Liquid Retardant- Test #3
After my observations in the last test, where the solid retardant was still largely ineffective, I made the switch to a liquid, and utilized 2 pans to gather the total water emitted to determine flow rate. In this setup, only water was used without retardant. As a result of this test, I was able to make modifications to the flow rate of the water, as well as deduce that the distance from the extinguisher to the fire needed to be closer.
Getting Closer- Test #4
This test was the first to utilize actual fire which was not artificially maintained by a lighter. Based on the results of the previous test, where the amount of water over the period of time was slightly lower than it should have been, I modified the flow rate of the water, as well as the air/water ratio within the canister. As a result of this test, I was able to hone the flow rate and radius even more in order to get a more effective suppression.
A Functional Design- Test #5
This was the first fully effective test of FACE, yielding 100% fire suppression in a complete and controlled manner. This test utilized a modified pressure and air/water ratio in order to achieve a longer water flow. As a result of this test, I finalized the golden ratios of elements within the canister, and decided to work on scaling up the effective radius of the extinguisher.
