But a separate breakthrough in electrical pulse generation \u2014 capacitors that provide a bigger jolt in a smaller package \u2014 that may reshape the future of naval\u00a0power.<\/p>\n<p>The railgun\u2019s electromagnets are designed to accelerate a Hyper Velocity Projectile from zero to some 8,600 kmph, about Mach 7. That velocity requires a lot of power. In early testing, the Office of Naval Research had relied on banks of commercial capacitors to pulse electricity to the gun. But they were \u201cnot suitable for integration aboard a ship\u201d \u2014 too large to fit aboard Zumwalt-class destroyers, as Thomas Beutner, head of\u00a0<span class=\"caps\">ONR<\/span>\u2019s Naval Air Warfare and Weapons Department, explained during a July event in\u00a0Washington.<\/p>\n<p>So\u00a0<span class=\"caps\">ONR<\/span>\u00a0researchers developed their own capacitors, more compact yet capable of supplying 20 megajoules per shot, with a goal of 32 megajoules by next year.\u00a0<span class=\"caps\">ONR<\/span>\u00a0said you can think of a megajoule as about the same, energy-wise, as a one-ton vehicle moving at 160 mph. These new capacitors \u201crepresent a new generation of pulse power, with an energy density of over a megajoule per cubic meter,\u201d said Beutner. The capacitors, which store energy, are also able to recharge quickly enough in order to fire ten times in a per\u00a0minute.<\/p>\n<p>The entire point of the railgun is that it\u2019s supposed to use the ship\u2019s power, rather than rely on volatile fuel or gunpowder. But relying on ship power for a cannon that shoots Volkswagens can create huge fluctuations and power spikes. And the Navy wants future ships to power a lot of other things in addition to railguns, such as\u00a0<a href=\"http:\/\/scout.com\/military\/warrior\/Article\/Navy-to-Fire-150Kw-Ship-Laser-Weapon-From-Destroyers-Carriers-101455353\" target=\"_blank\" rel=\"noopener noreferrer\">150-kilowatt dronekilling lasers<\/a>\u00a0and powerful radar and electronic warfare systems. All of these pose \u201cunique burdens on the power system,\u201d Beutner\u00a0said.<\/p>\n<p>The capacitors, by storing more power in a smaller shell, even out the amount of power the ship\u2019s generators have to produce, decreasing the possibility of a major electrical failure as a lasers, engine, railgun, and radar all (potentially) call for power at once. In this way, they serve not only as an energy store but also a sort of power\u00a0adaptor.<\/p>\n<p>That, in part, is why the new capacitors represent \u201can important scientific advance in terms of energy density in those capacitors. More importantly, that\u2019s a size factor that will fit on both current combatants and future combatants,\u201d said\u00a0Beutner.<\/p>\n<\/div>\n<p><strong>Fuente:<\/strong>\u00a0<em><a href=\"http:\/\/www.defenseone.com\/technology\/2017\/08\/us-navys-railgun-breakthrough-could-change-energy-storage\/139953\/?oref=defenseone_today_nl\" target=\"_blank\" rel=\"noopener noreferrer\">http:\/\/www.defenseone.com<\/a><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>El moderno ca\u00f1\u00f3n RAILGUN de la\u00a0U.S.\u00a0Navy est\u00e1 mostrando importantes avances\u00a0 al pasar del laboratorio a los ensayos operacionales e incluso al disparo en repetici\u00f3n.
