VIDEO:TUNUL ELECTROMAGNETIC,O NOUA SUPER-ARMA AMERICANA.The gun that can destroy an enemy 100 miles away .


Tunul electromaagnetic poate spulbera o tinta aflata la 160 km distanta prin forta  a unui proiectil lansat cu o viteza de opt ori mai mare decat cea a sunetului. Este vorba despre o noua “super-arma” a Fortelor Navale SUA, catalogata, in urma testelor balistice, drept cea mai puternica din lume.

O salva trasa cu tunul electromagnetic de la Centrul Naval Surface Warfare din Dahlgren, Virginia, SUA, a generat 33 megajouli forta pe teava, un record mondial pentru o astfel de arma, de trei ori mai mare decat cel anterior. Un singur megajoule se echivaleaza, aproximativ, cu o masina de o tona ce se deplaseaza cu viteza de 160 km/h. In cazul noii arme, impactul dintre proiectil si tinta va insemna de 33 de ori aceasta forta.

Proiectilul noii arme, cantarind aproximativ 9 kg, ar strabate in numai cateva minute o distanta de peste 150 km si ar lovi cu precizie absoluta tinta, la o viteza imposibila pentru armele conventionale. In loc sa mizeze pe forta propulsoare a exploziei prafului de pusca, tunul electromagnetic se foloseste de o gigantica unda de energie electromagnetica pentru a lansa „glontele” cu viteza de aproximativ 8 Mach. Proiectilul nu explodeaza la impact, dar distruge orice ar lovi prin forta bruta.

In prezent, navele de razboi americane pot atinge tinte aflate la aproximativ 20 km, dar acum, fortele navale spera ca noua arma le va permite sa lanseze focul pe o raza mult mai mare si cu o precizie sporita. Totusi, ar mai putea trece inca cinci, sau poate zece ani, inainte ca dispozitivul acesta  sa poata fi montat pe crucisatoare. Cercetatorii cred ca, pana in 2025, tehnologia aproape va dubla forta armei, capacitand-o sa lanseze un proiectil la o departare de peste 300 km in doar sase minute.

It will obliterate a target 100 miles away through sheer power using a bullet fired at eight times the speed of sound.

That is, if everything goes according to plan.

This supergun has been described as the most powerful in the world after tests at a U.S. Navy firing range.

Instead of relying on an explosive propellant such as gunpowder, the railgun uses a giant surge of electrical energy to fire the bullet at speeds approaching Mach 8.Instead of relying on an explosive propellant such as gunpowder, the railgun uses a giant surge of electrical energy to fire the bullet at speeds approaching Mach 8.

A shot fired by the electromagnetic railgun at the Naval Surface Warfare Centre in Dahlgren, Virginia, generated 33 megajoules of force out of the barrel, a world record for muzzle energy and more than three times the previous record.

A single megajoule is roughly equivalent to a one-ton car travelling at 100mph. The impact of the projectile hitting a target would be 33 times that force.

The bullet would take just minutes to fire over 100 miles and would hit with pinpoint accuracy with a velocity that’s impossible in conventional guns.

The hi-tech cannon fires a 20lb bullet or missile at a speed that is impossible in conventional guns. The makers claim it has pinpoint accuracy.

Instead of relying on an explosive propellant such as gunpowder, the railgun uses a giant surge of electrical energy to fire the bullet at speeds approaching Mach 8. The bullet doesn’t explode on impact but obliterates whatever it hits through sheer power.

Currently, U.S. warships can only reach targets about 13 miles away, but the navy hopes the new gun will allow attacks from a much safer distance.

Rear Admiral Nevin Carr, chief of naval research, said the gun could be aimed at a magazine on an enemy ship and ‘let his explosives be your explosives’.

But it will be at least another five years – possibly ten – before the weapon is ready to be used on ships.

‘People see these things in the video games, but this is real,’ said programme manager Roger Ellis. ‘This is what is very historical.’

In Friday’s tests, the gun fired a bullet 5,500ft through the woods. The shell caused a small sonic boom before dropping harmlessly back to earth.

But it was fired at a very low trajectory and scientists calculate it could have travelled up to 100 miles if fired at optimum trajectory.

The main obstacle the navy is trying to overcome in its research is to build up sufficient charge to allow the gun to keep firing at supersonic speeds.

The main obstacle the navy is seeking to overcome in its research – that has cost $211million over the last five years – is to build up sufficient charge to allow the gun to keep firing at supersonic speeds.

In Friday’s tests, it took about five minutes for the gun to power up before launching a bullet about 5,500ft through the woods, causing a small sonic boom before dropping harmlessly back to earth.

But it will probably be another ten years before the weapon is ready to be deployed on ships.

By 2025, scientists say the technology will almost double the power of the gun, enabling it to send a bullet 200 miles in six minutes.
