Railguns have limited potential to be used against both surface and airborne targets. Current railgun technologies necessitate a long and heavy barrel, but a railgun's ballistics far outperform conventional cannons of equal barrel lengths. Helical railguns  are multi-turn railguns that reduce rail and brush current by read more factor equal to the number of turns. Aufgrund der Rechtshändigkeit der Lorentzkraft wird das Projektil aus der Schiene heraus beschleunigt. However, plasma railguns are very different from solid mass drivers or weapons, and they only share the basic operational concept. To Aru Kagaku no Railgun jap. The destructive force of a projectile depends on its kinetic https://sm0wqt.se/hd-filme-stream-kostenlos/free-serie.php at railgun point of impact just click for source due to the visit web page high velocity of source railgun-launched projectile, their destructive force may be much greater than conventionally railgun projectiles of the same size. Wir haben einen Baum der Gemeinde gestutzt da er ständig seine Blätter in unserem Garten continue reading und unsere Pumpe am Pool verstopft. Retrieved July visit web page, See also: Coilgun.
The total launch package would weigh almost 1. This halves the required current through the rails, which reduces the power fourfold.
This decreases ammunition size and weight, allowing more ammunition to be carried and eliminating the hazards of carrying explosives or propellants in a tank or naval weapons platform.
Also, by firing more aerodynamically streamlined projectiles at greater velocities, railguns may achieve greater range, less time to target, and at shorter ranges less wind drift, bypassing the physical limitations of conventional firearms: "the limits of gas expansion prohibit launching an unassisted projectile to velocities greater than about 1.
Current railgun technologies necessitate a long and heavy barrel, but a railgun's ballistics far outperform conventional cannons of equal barrel lengths.
Railguns can also deliver area of effect damage by detonating a bursting charge in the projectile which unleashes a swarm of smaller projectiles over a large area.
Assuming that the many technical challenges facing fieldable railguns are overcome, including issues like railgun projectile guidance, rail endurance, and combat survivability and reliability of the electrical power supply, the increased launch velocities of railguns may provide advantages over more conventional guns for a variety of offensive and defensive scenarios.
Railguns have limited potential to be used against both surface and airborne targets. The first weaponized railgun planned for production, the General Atomics Blitzer system, began full system testing in September The company hopes to have an integrated demo of the system by followed by production by , pending funding.
Thus far, the project is self-funded. In October , General Atomics unveiled a land based version of the Blitzer railgun.
A company official claimed the gun could be ready for production in "two to three years". Railguns are being examined for use as anti-aircraft weapons to intercept air threats, particularly anti-ship cruise missiles , in addition to land bombardment.
A supersonic sea-skimming anti-ship missile can appear over the horizon 20 miles from a warship, leaving a very short reaction time for a ship to intercept it.
Even if conventional defense systems react fast enough, they are expensive and only a limited number of large interceptors can be carried.
A railgun projectile can reach several times the speed of sound faster than a missile; because of this, it can hit a target, such as a cruise missile, much faster and farther away from the ship.
Projectiles are also typically much cheaper and smaller, allowing for many more to be carried they have no guidance systems, and rely on the railgun to supply their kinetic energy, rather than providing it themselves.
The speed, cost, and numerical advantages of railgun systems may allow them to replace several different systems in the current layered defense approach.
The Navy plans for railguns to be able to intercept endoatmospheric ballistic missiles, stealthy air threats, supersonic missiles, and swarming surface threats; a prototype system for supporting interception tasks is to be ready by , and operational by This timeframe suggests the weapons are planned to be installed on the Navy's next-generation surface combatants, expected to start construction by India has successfully tested their own railgun.
Helical railguns  are multi-turn railguns that reduce rail and brush current by a factor equal to the number of turns.
Two rails are surrounded by a helical barrel and the projectile or re-usable carrier is also helical. The helical railgun is a cross between a railgun and a coilgun.
They do not currently exist in a practical, usable form. A helical railgun was built at MIT in and was powered by several banks of, for the time, large capacitors approximately 4 farads.
It was about 3 meters long, consisting of 2 meters of accelerating coil and 1 meter of decelerating coil.
It was able to launch a glider or projectile about meters. A plasma railgun is a linear accelerator and a plasma energy weapon which, like a projectile railgun, uses two long parallel electrodes to accelerate a "sliding short" armature.
However, in a plasma railgun, the armature and ejected projectile consists of plasma, or hot, ionized, gas-like particles, instead of a solid slug of material.
It is one of several United States Government efforts to develop plasma-based projectiles. The first computer simulations occurred in , and its first published experiment appeared on August 1, The weapon was able to produce doughnut-shaped rings of plasma and balls of lightning that exploded with devastating effects when hitting their target.
The project may or may not have been scrapped some time after Rail and insulator wear problems still need to be solved before railguns can start to replace conventional weapons.
This system was established in and has been operated for over 10 years. In a successor was created, project EDO-1, that used projectile with a mass of 0.
It used a track length of 0. China is now one of the major players in electromagnetic launchers; in it hosted the 16th International Symposium on Electromagnetic Launch Technology EML at Beijing.
The United States military have expressed interest in pursuing research in electric gun technology throughout the late 20th century due to how electromagnetic guns don't require propellants to fire a shot like conventional gun systems, significantly increasing crew safety and reducing logistics costs, as well as provide a greater range.
In addition, railgun systems have shown to potentially provide higher velocity of projectiles, which would increase accuracy for anti-tank, artillery, and air defense by decreasing the time it takes for the projectile to reach its target destination.
During the early s, the U. The main problem the U. Navy has had with implementing a railgun cannon system is that the guns wear out due to the immense pressures, stresses and heat that are generated by the millions of amperes of current necessary to fire projectiles with megajoules of energy.
While not nearly as powerful as a cruise missile like a BGM Tomahawk , that will deliver 3, MJ of destructive energy to a target, such weapons would, in theory, allow the Navy to deliver more granular firepower at a fraction of the cost of a missile, and will be much harder to shoot down versus future defensive systems.
For context, another relevant comparison is the Rheinmetall mm gun used on main battle tanks, which generates 9 MJ of muzzle energy. On January 31, , the U.
Navy tested a railgun that fired a projectile at A test of a railgun took place on December 10, , by the U. While similar in energy to the aforementioned test, the railgun used is considerably more compact, with a more conventional looking barrel.
A General Atomics-built prototype was delivered for testing in October In the U. A future goal is to develop projectiles that are self-guided — a necessary requirement to hit distant targets or intercepting missiles.
Some high velocity projectiles developed by the Navy have command guidance, but the accuracy of the command guidance is not known, nor even if it can survive a full power shot.
Currently, the only U. Navy ships that can produce enough electrical power to get desired performance are the three Zumwalt -class destroyers DDG series ; they can generate 78 megawatts of power, more than is necessary to power a railgun.
However, the Zumwalt has been cancelled and no further units will be built. Engineers are working to derive technologies developed for the DDG series ships into a battery system so other warships can operate a railgun.
Even if current ships, such as the Arleigh Burke -class destroyer , can be upgraded with enough electrical power to operate a railgun, the space taken up on the ships by the integration of an additional weapon system may force the removal of existing weapon systems to make room available.
The Navy is looking into other uses for railguns, besides land bombardment, such as air defense; with the right targeting systems, projectiles could intercept aircraft, cruise missiles, and even ballistic missiles.
The Navy is also developing directed-energy weapons for air defense use, but it will be years or decades before they will be effective.
The railgun would be part of a Navy fleet that envisions future offensive and defensive capabilities being provided in layers: lasers to provide close range defense, railguns to provide medium range attack and defense, and cruise missiles to provide long-range attack; though railguns will cover targets up to miles away that previously needed a missile.
One shot would require 6 million amps of current, so it will take a long time to develop capacitors that can generate enough energy and strong enough gun materials.
The most promising near-term application for weapons-rated railguns and electromagnetic guns, in general, is probably aboard naval ships with sufficient spare electrical generating capacity and battery storage space.
In exchange, ship survivability may be enhanced through a comparable reduction in the quantities of potentially dangerous chemical propellants and explosives currently employed.
Ground combat forces, however, may find that co-locating an additional electrical power supply on the battlefield for every gun system may not be as weight and space efficient, survivable, or convenient a source of immediate projectile-launching energy as conventional propellants, which are currently manufactured safely behind the lines and delivered to the weapon, pre-packaged, through a robust and dispersed logistics system.
In July, , Defensetech reported that the Navy wants to push the Office of Naval Research's prototype railgun from a science experiment into useful weapon territory.
A 32 megajoule railgun shot is equivalent to about 23,, foot-pounds, so a single 32 MJ shot has the same muzzle energy as about , Research on railgun technology served as a major area of focus at the Ballistic Research Laboratory BRL throughout the s.
Research into railguns continued after the Ballistic Research Laboratory was consolidated with six other independent Army laboratories to form the U.
Marine Corps and the U. Rapid-fire operation was achieved by driving the launcher with multiple peak pulses provided by the CCEMG compulsator.
The CCEMG railgun included several features: ceramic sidewalls, directional preloading, and liquid cooling. The U. Army Research Laboratory also monitored electromagnetic and electrothermal gun technology development at the Institute for Advanced Technology IAT at the University of Texas at Austin , one of five university and industry laboratories that ARL federated to procure technical support.
The facility also provided a power system that included thirteen 1- MJ capacitor banks, an assortment of electromagnetic launcher devices and diagnostic apparatuses.
The focus of the research activity was on designs, interactions and materials required for electromagnetic launchers.
In , a collaboration between ARL and IAT led to the development of a radiometric method of measuring the temperature distribution of railgun armatures during a pulsed electrical discharge without disturbing the magnetic field.
Using scanning electron microscopy and other diagnostic techniques, they evaluated in detail the influence of plasmas on specific propellant materials.
China is developing its own railgun system. In when the weapon system gained the ability to strike over extended ranges with increased lethality.
The weapon system was successfully mounted on a Chinese Navy ship in December , with sea trials happening later.
In early February , pictures of what is claimed to be a Chinese railgun were published online. Media suggests that the system is or soon will be ready for testing.
India aims to fire a one kilogram projectile at a velocity of more than 2, meters per second using a capacitor bank of 10 megajoules.
The package should be able to operate in the presence of any plasma that may form in the bore or at the muzzle exit and must also be radiation hardened due to exo-atmospheric flight.
Army's Dugway Proving Ground in Utah. The on-board electronics successfully measured in-bore accelerations and projectile dynamics, for several kilometers downrange, with the integral data link continuing to operate after the projectiles impacted the desert floor, which is essential for precision guidance.
Plasma railguns are used in Physics research and they have been explored as a potential trigger mechanism of magneto-inertial fusion.
However, plasma railguns are very different from solid mass drivers or weapons, and they only share the basic operational concept. From Wikipedia, the free encyclopedia.

Office of Naval Research. Die beschleunigende Kraft ist die Lorentzkraft : Die entgegengesetzten Schienenströme erzeugen zwischen den Schienen ein senkrecht zur Fläche zwischen den Schienen stehendes Magnetfeld.
Aufgrund der Rechtshändigkeit der Lorentzkraft wird das Projektil aus der Schiene heraus beschleunigt. Die Kraft auf das Geschoss ist nur von Magnetfeldstärke und Stromfluss abhängig und daher unabhängig von der Geschwindigkeit.
Als Stromquelle bzw. Energiespeicher kommen Superkondensatoren in Form von Impulsgeneratoren zum Einsatz. Alternativ werden auch Schwungräder als Energiespeicher verwendet, in diesem speziellen Fall Unipolarmaschinen oder deren Weiterentwicklung, die Compulsatoren.
Dort sollte bis der Prototyp einer funktionierenden Panzerkanone mit einem Kaliber von 60 Millimetern gebaut werden, die auf dem Railgun-Prinzip beruht.
Bisher waren mit allen Versuchsaufbauten nur wenige Schüsse möglich, bevor die Anlagen ausfielen. Die US Navy forscht in Washington an Railgun-Schiffsgeschützen, deren Geschosse auf bis zu Mach 7 beschleunigt werden, mit Mach 5 wieder in die Erdatmosphäre eintreten und eine Reichweite von mehr als Kilometern erreichen sollen.
BAE setzte als Ziel bis einen ersten Prototypen mit einer Energie von 32 Megajoule und bis einen mit 64 Megajoule fertigzustellen, während die Navy davon ausgeht, bis einen ersten einsatzfähigen Prototyp mit zugehörigen Unterstützungssystemen testen zu können.
Es soll auch eine Variante zur Abwehr von Interkontinentalraketen geben. Bis wurden rund 36 Millionen US-Dollar in das Projekt investiert, bis waren weitere Millionen eingeplant.
Ende Januar berichtete die Navy von einem Versuchsaufbau, der die bis dahin besten Leistungsergebnisse erbracht haben soll.
Das Aluminium-Geschoss erreichte dabei eine Energie von 10,68 Megajoule. Am General Atomics schätzt, dass die Waffe bis spätestens regulär auf Zerstörern der Arleigh-Burke-Klasse verwendet werden kann.
Der Prototyp ist vollständig transportabel. Im Zweiten Weltkrieg gab es Versuche durch deutsche und japanische Wissenschaftler, diese waren allerdings weitgehend erfolglos und wurden nach Kriegsende von den Alliierten übernommen.
Jahrhunderts Versuche unternommen wurden, leistungsfähige Railguns zu entwerfen, befinden sie sich noch immer in einer Entwicklungsphase.
Sie sollte der Raketenabwehr und als Antisatellitenwaffe dienen. Dort wurde eine MJ-Anlage installiert.
Railguns waren auch als Antriebsmethode für die Raumfahrt im Gespräch.
