	The '''combustion process''' is an exothermic chemical reaction of a ~~chemical~~ with ~~oxygen~~. In the context of [[combustion cannon]]s and [[hybrid]]s, this refers to the reaction of a [[fuel~~]], usually a hydrocarbon~~ (usually [[propane]]) with atmospheric oxygen, producing carbon dioxide, water, and heat. The heat produces ~~sufficient~~ [[pressure]] ~~to propel~~ the projectile out the [[barrel]].		The '''combustion process''' is an exothermic chemical reaction of a fuel with an oxidizer. In the context of [[combustion cannon]]s and [[hybrid]]s, this refers to the reaction of a hydrocarbon fuel (usually [[propane]]) with atmospheric oxygen (the oxidizer), producing carbon dioxide, water, and heat. The heat produces [[pressure]] that propels the projectile out the [[barrel]].

	This burning takes place mostly on the "flame front", a stereotypically shell-shaped region that spreads outwards from the [[ignition source]]. Techniques used by some to encourage the rapid spread of this flame front <i>(to decrease the time it takes to combust all the fuel-air mixture, allowing the gases to reach peak pressure quickly, which has been shown to improve performance, especial on short-barrel launchers.)</i> Include:
	* multiple ignition points, allowing multiple flame fronts; usually accomplished via a [[spark strip]].
	* inducing turbulence into the flow containing the flame front; usually accomplished via a [[chamber fan]].

	The latter is not a well established way of doing things, but the latest attempt by DR shows promise; an adaptation of the [[jet ignition]] idea, in which an inherently turbulent spire of flame is squirted into the main chamber through a small orifice.

			This burning takes place in a "flame front", typically a spherical or domed shaped region that spreads outwards from the [[ignition source]]. It is generally believed that the faster the flame front moves the better a combustion spudgun will perform. Techniques used by some to encourage the rapid spread of this flame front include:
			* Multiple ignition points to produce multiple flame fronts. This is usually accomplished via multiple [[spark gap]]s, or perhaps by use of a [[spark strip]].
			* Inducing turbulence in the gases through which the flame front is moving. This is usually accomplished via a [[chamber fan]].
