A pneumatic potato cannon A large pneumatic design: The projectile is loaded in the muzzle (not pictured), which is then attached to the cannon (at 2). The air reservoir (3) is filled to 120 psi (0.83 MPa) using the Schrader valve (4). Upon opening the solenoid valve (1), the air from the reservoir is transferred to the projectile, which is ...
Spud gun. A typical factory-made toy die-cast spud gun. The cap attached to the muzzle converts it into a water pistol. A spud gun or potato gun is a small toy gun used to fire a fragment of potato. To operate, one punctures the surface of a potato with the gun's hollow tip and pries out a small pellet which fits in the muzzle.
The action, or the mechanism by which subsequent rounds are automatically reloaded, must also be powered by the air pressure; that is not a major drawback as pneumatic tools such as the nail gun proves as long as you carry an air tank and compressor around with you. The weapon has to supply or be supplied with a source of very high pressure gas.
The usual recoil system in modern quick-firing guns is the hydro-pneumatic recoil system. In this system, the barrel is mounted on rails on which it can recoil to the rear, and the recoil is taken up by a cylinder which is similar in operation to an automotive gas-charged shock absorber, and is commonly visible as a cylinder mounted parallel to ...
Pneumatic cannon. Pneumatic cannon may refer to: Dynamite gun, any of a class of artillery pieces that use compressed air to propel an explosive projectile. FN 303, a semi-automatic less-lethal riot gun. Holman Projector, a naval anti-aircraft weapon. M61 Vulcan, a hydraulically, electrically, or pneumatically driven, six-barrel, air-cooled ...
The development of the M18A1 mine dates back to work done during World War II. The Misnay–Schardin effect was independently discovered during that war by József Misnay, a Hungarian, and Hubert Schardin, a German. When a sheet of explosive detonates in contact with a heavy backing surface (for example, a metal plate), the resulting blast is ...
Category. : Pneumatic weapons. A pneumatic weapon is a weapon that fires a projectile by means of air pressure, similar in principle to the operation of pneumatic tube delivery systems. The term comes from a Greek word for "wind" or "breath" (πνεύμα). Wikimedia Commons has media related to Pneumatic weapons.
Vacuum bazooka. A vacuum bazooka is a pipe-based cannon which uses a vacuum pump (often a vacuum cleaner) to reduce pressure in front of the projectile and therefore propel a projectile as a result of the air pressure acting on its reverse. The concept was originally proposed by Neil A Downie in 2001 [1] but many variations have been built ...
