Physics of a Spudgun :: physics potato gun cannon

swell its quite simple actually. Spudguns use some of the same principles as interior combustion engines. Just as burning gas forces a piston step up of a cylinder it bottomland excessively force out a potato. A spudgun is a contrivance that uses some form of propellent to project a potato across the sky. Usually these devices are do of ABS plastic sewer pipe. There are several major separate of the spud gun that these pages allow for refer to. These parts are the touchwood chamber, the igniter, and the barrel. The ignition device of a spud gun is simply honk the spark generator that causes the combustion of the fuel in the electric arc chamber. This device is usually a charcoal radiator grille visible light. The stillton on the spark arrester is depressed and a spark arcs across a wire leash and a ground wire. The grill sparker is installed in to the back of the firing chamber by means of threading, epoxy, and bolts. This sparker becomes a projectile if it is no t well seated in the end cap of the firing chamber. It essential be held firmly in place withstanding any pressure produced by the fuels being burned in the chamber. This type or igniter will work in most conditions including when it becomes wet with fuel. Other igniters exist but are not recommended as highly as the charcoal grill sparker. The Colmen lantern spin lighter which use a flint and striker can become gummed up with some fuels and is not recommended for use in spud guns which will use hairspray as a primary fuel. This lighter must have new flints installed when they run out. This type of lighter also will fail to function when wet with fuel. The flame style barbecue lighter is a click lighter that produces a small-sustained flame. This lighter seldom misfires but is very hard to install given the high pressures it would be subjected to. Also the fuel in the lighter it self must be refilled. Some Spud Guns use a spark plug and outpouring setup that involves more tha n work as well as more components. The benefits of this style of ignition system is that you have the ability to remote depart the fuel from a safe distance. By far the push spill charcoal grill sparker is the recommended igniter. It is cheap, effective, relatively easy to install and dogged lasting.
