A large air vortex cannon, with a 9 feet (2.7 m) wide barrel and a displacement volume of 2,873 US gallons (10.88 m 3) was built in March 2008 at the University of Minnesota, and could blow out candles at 180 feet (55 m). [6] [7] In 2012, a large air vortex cannon was built for Czech Television program Zázraky přírody (lit. ' Wonders of ...
The Ares Incorporated XM274 (originally designated as the medium caliber, antiarmor automatic cannon, MC-AAAC) was an American smoothbore 75mm autocannon designed by Eugene Stoner. [1] It used a rotating breech block with cased telescopic ammunition. It was developed for the HIMAG program, but was later used on a variety of test vehicles. [2]
A barrel roll attack is a military maneuver that improves the attacker's offensive position and prevents the attacker from overshooting. In this maneuver the defender breaks one direction and so the attacker performs a barrel roll in the opposite direction. The attacker pulls back on the stick more than a normal barrel roll, performing a ...
A barrel bomb is an unguided IED made to be dropped from helicopters and fixed-wing aircraft. A lob bomb is a rocket-fired IED. Barrack busters were improvised mortars used by the Provisional Irish Republican Army during The Troubles. Acid packets were used by rioters during the Citizenship Amendment Act protests in India [63]
The Brocock Air Cartridge System, for example, uses a self-contained "cartridge" roughly the size of a .38 Special cartridge, which contains an air reservoir, valve, and a .22 caliber (5.5 mm) pellet. Examples of BACS airguns converted to firearms, either by drilling the barrel out to fire a .38 Special cartridge or by altering the cylinder to ...
The cannon barrel is about 3 feet long, mounted on wheels and towed. It is muzzle loaded. An explosive such as ANFO is first dropped into the muzzle and tamped with a wooden stick. The projectile is a re-purposed gas cylinder filled with explosives and shrapnel (the payload). Welded to the payload is about a 2-foot metal tube (the tail) about ...

A lightweight bursting disk such as a piece of paper can be secured simply by the vacuum action when it is held against the barrel. The maximum velocity the projectile reaches is about 650 mph (1,050 km/h). [citation needed] The velocity of a projectile in a vacuum cannon can be modeled.
