A chamber fan is a device used in combustion or hybrid cannons for creating an even mixture of fuel and air within the chamber, and/or venting the chamber between shots. The commonly used fan is a CPU or case fan from a computer, these use brushless motors which do not create sparks that can ignite the fuel/air mix. A chamber fan setup also has a switch to operate the fan, and a power source such as batteries to power it. It can also be controlled automatically using a timer circuit which turns the fan off when it's 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.
- inducing turbulence into the flow contaning the flame front.
The effects on cannon performance include increased muzzle velocity, and the ability to quickly vent the chamber of exhaust gases.
