Conventional guns, such as cannons, 155 mm howitzers, and multiple-launch rocket system (MLRS), utilise the chemical energy derived by igniting a charge of chemicals (gun powder). The maximum velocity at which the penetrator can be propelled is approximately 1.5-2.0 km/sec. On the other hand, electromagnetic launchers (EML guns), or railguns, use the electrical energy, and the concomitant magnetic field (energy), to propel the penetrators/projectiles at velocities up to 10 km/sec. This increase in velocity results in greater kinetic energy for the same penetrator mass. The greater the energy, the greater is the damage inflicted on the target. For this and other reasons, the DoD (especially, the U. S. Army) has conducted extensive research into the railguns. …show more content…
Also, they need to be so strong and rigid that the railgun does not sag while firing and buckle under its own weight. The obvious choice for high electrical conductivity is copper. However, the railguns made out of copper wear out much too quickly due to the erosion of the rails by the hypervelocity projectiles and they lack high-temperature strength. The wear and erosion of copper rails necessitate inordinately frequent barrel replacements. In order to satisfy these requirements, a nanocrystalline composite material made of tungsten, copper, and titanium diboride is being evaluated as a potential candidate. This nanocomposite possesses the requisite electrical conductivity, adequate thermal conductivity, excellent high strength, high rigidity, hardness, and wear/erosion resistance. This results in longer-lasting, wear-resistant, and erosion-resistant railguns, which can be fired more frequently and often than their conventional
Prior to the invention of the Minié ball it was necessary for the bullet to be the same diameter as the barrel in order for it to engage the rifling. This made it difficult and time consuming to load because the bullet would have to be rammed down the barrel with some force. Due to this fact, muzzle loading rifles had not seen any previous use in combat. The Minié ball, however, changed this. The Minié bullet was slightly smaller in diameter than the rifle barrel, was conical in shape, and contained an iron plug in its hollow base. When fired the force of the expanding charge would force the iron plug into the base of the bullet, thus causing the base to expand slightly and engage the rifling. The Minié bullet, fired from a rifled musket, had an effective range of up to 250 yards, which was a vast improvement over earlier muskets and ammunition. The rifled musket firing the Minié ball became the most common firearm used by both sides during the Civil War, and the Springfield armory in Massachusetts produce nearly two million for the Union Army.

size. The muzzle velocity is at 2,800ft/sec (853m/sec) with also a rate of fire 725 rounds per
Left, right, Liberal, Conservative, Democratic, Republican. There are a lot of synonyms for the sides of our nation divided. Divided on many things: religion, political views, morals, etc.. For a nation that prides ourselves on extraordinary security and unity, it is quite ironic that so many issues can cause such distress and uproar within communities. One such issue is gun control. As a white male in a middle-lower class family that has never owned a gun, I may be somewhat biased. Objectively as I can, I am going to report the facts and more importantly, try to find the core issues at play.
A gun has a high muzzle velocity and a very flat trajectory. Normally a gun is used in a direct fire mode where the target can be seen and penetration is desirable. Good targets for a gun would be things like brick or earth forts, ships, buildings, and targets in tree lines. Howitzers have a somewhat lower muzzle velocity and arc their shells onto a target. They are used in both direct fire and indirect fire mode.
Today in the United States there has much debate over the countries current standing on Gun Control. Some Americans lean more towards supporting the bans, simply due to what people have seen with the mentally ill in the media today, these are often the indviduals who support restrictions that have been made on the purchasing of firearms. Others highly oppose gun control, standing firm by the belief that any form of suppression towards firearm ownership, is a clear violation of anyone 's constitutional rights. "In 1990, the Violence Policy Center announced that the debate must be switched from small handguns to large “assault rifles.” This led to states like California starting bans themselves on, "assault weapon magazines holding more than
During the Revolutionary War, the Artillery assets that were available were a combination of cannons, mortars and howitzers. There were two types of cannons used at this time. The Field Guns, which were lightweight and easier to move, and the Siege Guns, which were much heavier and less mobile. The cannons utilized three different types of rounds. The rounds were solid shot, grapeshot, and canister. The solid shot rounds were used for structures, buildings, and ships. The grapeshot, which was a canvas bag of lead or iron balls, was ideal for long range personnel. The canister shot was a wooden cartridge carrying iron balls and when fired would explode like a shotgun for shorter range personnel. The cannons were mostly low trajectory as opposed the mortars which were high trajectory and fire bomb shells. The mortar was based on a wooden platform and a wedge of wood was used to incline the front of the barrel. There were land service mortars and sea service mortars. The land service being more mobile and the sea service much heavier and were permanently positioned on ships. By the time of the Revolutionary War there were nine types of land service mortar and four types of sea service mortar. They ranged from 4.4 to 13 inches. The rounds fired out of mortars were designed to fire at a high trajecto...
Gun control has stirred an incredible amount heated debates and controversy in this country. Both sides believe that their view is the correct view. The question remains: Will controlling firearms result in less firearm deaths? The answer to that question is no. This is both proven and obvious. First is the point that criminals have never and will never obey the law, which is why they are criminals. The United Kingdom has an incredibly strict gun control policy but yet their murders involving a knife or other sharp edged weapons has a dramatic increase compared to our own. The second point is that there is already gun control implemented in many places, so gun control can easily be studied. The Brady Campaign to Prevent Gun Violence studies and ranks all 50 states from the most strict to the most lenient. When comparing this with the FBI database of crime reports it will show that the strictest gun law states have the highest rate of firearm related murders than the state that is much more lenient. These two points come together to show that gun control will not work and is impractical.
It can also fire 700-900 rounds per minute while in fully auto mode. The M-16 also had a secondary attachment called the M-203 which could fire a grenade up to 400m with a 5m casualty radius” (Meyerson). The U. S. Soldiers also used the M-60 light machine gun that could be mounted on tanks and helicopters and used as an artillery weapon. They also used the “105 mm Howitzer that shot explosive shrapnel bombs that have a fire rate of 3 to 8 rounds a minute” (History.com). The Howitzer was also used like the M 60 machine gun by being mounted to tanks and helicopters.
trying to implement laws that will keep weapons out of the hands of every one.
Gun violence in America is a public health crisis, which needs to be recognized and changed by legislatures, and the voting American. As conscious Americans, we need to vote for changes to gun laws that would improve background checks nation-wide, make firearm registration mandatory, restrict the sale of assault weapons and weapon modifications that give the shooter military-grade fire power, and invest in gun-safe technology and safe firearms storage designs. This type of technology will help prevent criminally oriented people from accessing guns, and will help prevent the accidental deaths of many children by guns. This essay will explain the reforms needed to help ensure Americans can still exercise their 2nd amendment right of owning firearms, and preventing the unnecessary deaths of many Americans at the same time.
The debate over gun control in America has constantly brought up over the years due to gunmen killing large amounts of civilizations in shootings. From Columbine to Sandy Hook or the shootings of the two reporters in West Virginia, these public shootings are occurring everywhere. Lawmakers and civilians alike are pushing for increased gun control in hopes of preventing the same tragedies. Anybody that has been affected by the shootings have been pushing Congress and state governments to force new sanctions on government. With the past three years, Congress has shot down all the laws despite the large amounts of public support. Adding more gun control isn’t going to stop the mass shootings from happening.
I choose this experiment because I am a hunter and having an accurate rifle is a good thing. In hunting the first shot counts. Now here is my data I got from the experiment but first a little history on the guns the .234 is a small hunting rifle use on deer and other small game. The .270 is a med. game rifle for deer and up to small elk. The 30-.06 is a large game rifle for elk and up to moose. My problem is the I wont to find out what is the most accurate rifle is. My hypothesis is if three rifles are tested for accusey then what is the most accurate the .270 is the most accurate rifle because a lot of people think the .270 is the most accurate rifle so I am going to test it. So I some research on my experiment I look to be one of the first one to do this
Gun control is an awfully big issue in the United States today. Many people in America don’t agree with the gun control laws that they have today. Gun control laws only take guns and freedom away from law-abiding citizens. Many citizens have their own reasons for owning a gun. Why would the government want to make it harder for people to own a gun? People that own guns aren’t very likely to be attacked by criminals. Owning a handgun is one of the best ways of protection when used correctly. The second amendment states “the right to bear arms”; does this grant everyone the right to own a gun? Gun control laws have not been proven to do anything for citizens. Gun control laws just make it harder for the good guy average Joe to own a gun. Gun control laws are not a good idea, and are taking part in the loss of our freedom that was given to us.
