Solid propellant fire extinguishing system

A fire extinguishing system, comprising:

• a hermetically sealed storage canister fabricated with at least one gas outlet and defining a hollow within, wherein the canister has an oval shape, wherein the canister has an area defining a flat surface formed on an external surface thereof;
• a powder form fire extinguishing agent stored inside the canister, wherein the fire extinguishing agent is subjected to hydrophobization prior to filling the canister;
• a potassium nitrate based solid propellant that is ignitable to generate gases and is stored inside a tubular member, wherein the tubular member has a first end fixed around a top portion of the canister and a second end defining a gas outlet point that is buried into the fire extinguishing agent, wherein the solid propellant is positioned within the canister;
• and
• a rupturable seal disposed at the gas outlet, wherein the solid propellant generates gases to sufficiently aerate the fire extinguishing agent inside the canister and build a positive gas pressure until the gas pressure is sufficient to rupture the seal for discharging the fire extinguishing agent under a pressurized gas flow;
• wherein the oval shape of the canister promotes aeration of the fire extinguishing agent such that the fire extinguishing agent is evenly distributed within the canister.
