Storm Tested Many of our shelters were in the path of the EF5 storms of April 27, 2011 - they all survived without damage. Aqua Marine Enterprises, Inc., manufacturer of Safe-T-Shelter® safe rooms, has been manufacturing and installing storm shelters since 1995. Metal Storm Limited was a research and development company based in Brisbane, Australia that specialized in electronically initiated superposed load weapons technology and owned the proprietary rights to the electronic ballistics technology invented by J. Mike O'Dwyer. The Metal Storm name applied to both the company and technology.

Contents.Technology Metal Storm used the concept of; multiple loaded nose to tail in a single with propellant packed between them. The, a traditional design, employs the same basic concept; however, the continues to burn in the Roman candle's barrel, igniting the charge behind the subsequent projectile. The process is repeated by each charge in turn, ensuring that all projectiles in the barrel are discharged sequentially from the single ignition. Various methods of separately firing each propellant package behind stacked projectiles have been proposed which would allow a 'shoot on demand' capability more suitable to.The concept of superposed loads was first applied to firearms in 1558 by the Italian inventor. The experimental Chambers gun, created in the 1790s in Pennsylvania, was a seven-barrel tripod-mounted firing superposed loads in a similar manner to the Metal Storm gun, but neither superposed small arms nor mounted guns saw any real military use due to their expense and impracticality., an Australian inventor, observed that these methods did not eliminate the problem of unintended propellant caused by highly pressurized hot 'leaking' past the remaining projectiles in the barrel ( blow-by) and igniting their charges. 's original Metal Storm demonstrated a method whereby projectiles placed in series along the length of a barrel could be fired sequentially and selectively without the danger associated with unintended propellant ignition.In the original Metal Storm patents, the propellant immediately behind the projectile closest to the of the gun barrel was ignited by an electronically fired, the projectile was set in motion, and at the same time a acted on the remaining stacked projectiles in the barrel, pushing them backwards.

By design, the remaining projectiles would under this load, expanding radially against the gun barrel wall. This created a seal ( ), which prevented the hot propellant gases (expanding behind the lead projectile) from leaking past them and prematurely igniting the remaining propellant charges in the barrel. As each of these propellant charges was selectively (electronically) ignited, the force 'unlocked' the projectile in front and propelled it down the gun barrel, and reinforced the radial expansion (and hence the seal) between the projectiles remaining in the barrel and the barrel wall.Subsequent designs discarded the 'distorting shell sealing against the barrel' concept in favour of containing the propellant in 'skirts' that form the rear part of each projectile. These skirted projectiles differ from conventional and units in that the skirts are part of the projectile, and in that the skirts are open-ended (at the rear).

The rearward seal to the skirt is provided by the nose of the following projectile in the barrel. As in the previous design, the firing of a projectile results in a rearward on the remaining projectiles stacked in the barrel.

This results in the skirts of the remaining shells in the barrel being compressed against the following shell heads, effectively creating a seal that prevents hot gases in the barrel triggering unintended propellant ignition ('blow-by') along the length of the barrel. Metal Storm also introduced inductive electronic ignition of the propellant, effectively from outside the barrel.

History Sometime in 1983, Mike O'Dwyer sold his trade business in order to work on Metal Storm.In June 1997, the first 36-barrel prototype was unveiled.In 2000, Chinese agents approached Michael O'Dwyer and offered him 100M to go to China to develop the technology. O'Dwyer refused and informed the Australian government of the approach.

Nonetheless, the concept behind the weapon system generated some interest in China such that research was carried out to investigate the utility of such a weapon for use onboard naval vessels and armored vehicles, in the latter case even for the purpose of intercepting incoming anti-tank guided missiles.In June 2003 Metal Storm entered into an agreement to provide technology to Thunderstorm Firefighting Pty Ltd to help develop a civilian application of its technology to help with bush fire fighting activities.

The Multi-shot Accessory Underbarrel Launcher, or MAUL, is a combat shotgun designed by defunct Brisbane-based company Metal Storm.^[1]

Design[edit]

The MAUL is a shotgun based on Metal Storm's electronically initiated superposed-load technology. In this concept multiple projectiles, in this case of 12-gauge bore, are loaded nose to tail in a single gun barrel with propellant packed between them. Each projectile is ignited sequentially using an electrically fired primer: the electrical charge is provided by a battery. ^[2] The weapon fires once per trigger pull: while in effect this is semi-automatic, in strict terms it is not as no energy from firing is used to automate any part of the weapon's operating cycle. Football manager handheld 2011 for sale by owner. Designed to be used as either a standalone weapon or an underslung module of a combat rifle such as M4 or M16^[3][4] via the use of Picatinny rail, it can also be used in a standalone configuration through the addition of a pistol grip, folding stock or both. ^[5]The central module is made of carbon fiber, while the barrels are steel.^[2] The resulting weapon weighs less than 800 grams (1.8 lb),^[3].

In its underslung configuration, it was boresight-aligned to the host gun's sighting system.^[2]

It was intended to fire a range of loads; buckshot, slug, Door breaching slugs, and several kinds of less-lethal loads including blunt-force, electro-muscular incapacitation and frangible nose chemical and marker munitions.^[3] Loads were intended to be provided in their own munition tubes, with the operator switching tubes to change ammunition type.

Metal Storm reported the first shoulder-firing of the MAUL during tests on 24 April 2009 at its test facilities in Chantilly, Virginia. ^[2].

Contracted Work[edit]

• Papua New Guinea: As of 3 August 2010, Metal Storm signed a contract with the Correctional Services Minister Tony Aimo to supply 500 standalone MAULs and 10,000 less-lethal barrels for use by correctional services officers.^[1] As of January 2011, this contract was awaiting ratification from the PNG government.
