Chamber fan

A chamber fan is a device used in combustion or hybrid cannons to create an even mixture of fuel within the chamber. A chamber fan system usually consists of a CPU or case fan from a computer, a switch to operate the fan, and a power source such as batteries to power the chamber fan. The fan is usually controlled manually by a switch but sometimes a timer circuit is employed to automatically turn the fan off when not needed.

The benefits of using a chamber fan include, but are not limited to:

• Mixing the fuel within the chamber to provide an even distribution.
• Venting the chamber of exhaust gases after a shot.

The effects on cannon performance include increased muzzle velocity, and the ability to quickly vent the chamber of exhaust gases.
