Kaufen Sie Pneumatik bei Europas größtem Technik-Onlineshop Nummer 1 Marktplatz in Deutschland I have one question though, when I fire my spud gun the RainBird sprinkler valve I use sounds like a airhorn, is there a way to fix that? Reply. Comment by Extreme Pneumatic vs Combustion; Spud Gun Construction - Pneumatic Style; Uncategorized; Archives. June 2007; Blogroll. Spud Files; Spud Gun Extreme; Calendar. April 2021; M T W T F S. Pneumatic spud guns are generally more powerful than combustion spud guns; a typical combustion gun generates chamber pressures of 10-70 PSI / 69 - 483 kP, while the average pneumatic gun can operate at pressures in the vicinity of 100 psi / 690 kP, or higher My take on all of this is that both kinds of guns have advantages and disadvantages. I a one of each style gun and enjoy them both. June 27, 2007 Categories: Pneumatic vs Combustion. . Author: Extreme Spud Master. Comments: Leave a commen

The two basic types of spud gun -- combustive and pneumatic-- each use a rapidly expanding volume of gas to move a potato. Both types of guns are typically made of PVC pipe, although some people use acrylonitrile butadiene styrene (ABS), aluminum or other piping materials. A combustion-based spud gun, says Suprise, uses a flammable vapor. A pneumatic spud gun uses the same principles of force as a combustive gun. However, instead of using an explosion to generate force, it uses compressed air. This content is not compatible on this device. A pneumatic spud gun generally has a larger chamber than a combustive model Pneumatic spud guns are generally more powerful than combustion spud guns. A typical combustion gun generates average chamber pressures of about 30 psi (210 kPa) with peaks of around 70-100 psi (500-700 kPa), while the average pneumatic gun can operate at pressures in the vicinity of 100 psi (700 kPa)

substantial it is not nearly as high as that of the pneumatic guns. The selection of Propellants is quite possibly the most important part of spud gun performance. The propellant is the fuel burned during combustion. This combustion creates the pressur The combustion of propane in air generates about 135 a spud won't even exit the barrel at a C:B this low. Clearly, there are more complex factors affecting the optimal C:B ratio of a combustion spudgun. Suggestively, the optimal C:B ratio for pneumatic guns, as predicted by GGDT are in the vicinity of 0.2~0.3, close to the simple minded. Since air is only ~21% oxygen we can calculate that for every unit of volume of the chamber we need (1C 3 H 8 /5O 2)*(0.21) = 0.042 volumes of fuel. 0.042 volumes of fuel is the same as 4.2% of fuel. (There are some subtleties about calculating the actual volume percent that'll be discussed below.) Common Fuels for Combustion Spud Guns Heats of. A potato gun, also called a spudzooka, potato cannon, and spud gun, makes for an entertaining project that also demonstrates a few laws of physics along the way. Part of the thrill of constructing a potato gun comes from experimenting with the basic design to get the best performance, all while learning valuable engineering lessons

It's really simple to make, but don't underestimate its power. They can shoot straight through a pretty thick sheet of plywood and break w When considering a combustion gun it is a good idea to take into account where you live. I live in the boondocks on a 300 acre farm. I can make as much noise as I want & only my mother will care. However if you line in an urban area with lots of snoopy & bitchy people, combustion might be a wise 2nd choice This causes the fuel/air mixture to ignite there first, and the combustion byproducts blow the potato out of the barrel with kind of a FOOOMP sound, while the residual fuel/air mixture continues to burn inside the gun. The spud cannon acts as a muffler, suppressing the combustion flash and some of the sound

Stun gun ignition is a spud gunners best friend. Stun guns produce a very powerful spark and make it very easy to wire multiple sparks into your chamber. There are several reasons why I feel this way about stun guns. The following list contains pros and cons of stun gun usage, as well as a few tips on using one. Pros: 1. Stun guns are cool I had an idea of using this principle on a spud gun, a hybrid between the combustion types (hairspray fueled typically) and compressed air guns. Meter in propane, then add compressed air. When spud passes over a switch, a spark plug fires, increasing pressure by combustion. Never made it..still have the plans somewhere

Spud guns or potato cannon's have been around for a long time. For some reason, I'm shocked that more hams don't use them for putting up wires. QST did an article awhile back on the topic getting people started, but not a lot of activity since (at least from what I've found online and locally) Glade Air Freshener: Has propane, butane, isobutane as propellants, powerful, but has a large percentage of water and smelly stuff. Starting Fluid (Either) Very powerful, but a little difficult to measure out, usually 1/2 a second will be enough fuel. Hard to get a small enough amount of fuel. Static Guard (for static on clothes

The cannon is also very useful for launching spuds huge distances, but compressed air at 100psi will pack much more power than a combustion spud gun for either of these purposes.

Air guns have existed since the 15th century There are three different types of spud guns. Combustion, Pneumatic and a hybrid of the two. Pneumatic is a bit more pricey to build than the combustion but it is the safest. It uses compressed gas to launch the spud. Because I am cheap, and I live in a country with free quality medical care (ACC), I built the combustion type

  1. He's made a spud gun from PVC pipe, powered by compressed air. It takes the form of a U-shaped tube with one side of the U being a pressure vessel separated from the other by a ball valve.
  2. The range of pneumatic cannons is more variable than the range of combustion spud guns due to the increased variation possible in the components. Typical ranges are slightly higher because of the greater power, but the maximum range of some high power pneumatic cannons has been said to be over 1,000 metres (1,100 yd )

Keep in mind that although PVC is pressure rated, I am sure that the pipe and fittings are not Sigma 3 tested for failure like rock climbing equiment and air plane parts So I finally built a mini spud gun. Several of them could fit inside the combustion chamber of the Splorg spud gun. The ported barrel is 1/8x6 and the combustion chamber is 1/2x2. I've tried denatured alcohol and propane as fuels and the latter is significantly better. Dunno what the range is but I'd guess that it's around 100-150' so far

The combustion design is the simplest and most common kind of spud gun. A projectile is loaded into the barrel. Fuel is added to the chamber behind the barrel (with the correct fuel/air ratio), and then ignited, blasting the projectile out The Mini T-Rex was my first potato gun that I designed totally by myself. It has a 3 inch expansion chamber with a 3/4 inch barrel. The best three things about the mini-rex are: it shoots almost as far as a big spud gun, you can get 6 shots per potato (vs. 1 or 2 for big ones), and it is quieter.

While laying down on his stomach, Pablo launches a potato through a spud gun that is angled upward from the ground at an angle of θ. The initial velocity of the potato is 132 m/s (this is a very high powered pneumatic spud gun that uses acetylene as a combustion agent) A chamber fan is a good addition to any spud gun. The purpose of a chamber fan is to provide a better fuel mixture inside of the combustion chamber. If you have ever used a spud gun in cold weather, you may have noticed a decrease in performance. This is due to the fact that the fuel (in my case propane) molecules do not move as fast when cold Ventilation is the key to assuring that if you have a vapor leak that is ignited, at worst, it becomes a flamethrower and you are not placed inside a potato gun. Consider the operation of an internal combustion engine in your car. Flood the engine, too much fuel, no combustion; not enough fuel, too much air, under the LFL, no combustion

First and foremost NEVER take off the cap and start clicking away at the igniter With the plans I am using, the piece of potato should be exiting the barrel at around 500km/h (138.8m/s). I think the sound barrier challenge is achievable using a hybrid cannon. I'm thinking of filling a chamber with compressed air, and remotely pumping a propane/butane mixture in
