U.S. military research and development of ultra high speed artillery or into an important force in the future anti missile (Figure) – Sohu military channel data figure: U.S. military launched hypervelocity projectile test. According to the Navy information network reported on September 19, 2016, after the government and the private sector into consideration, the United States Department of defense will no longer have railguns as an important platform for the next generation of anti missile, but is developing a super high speed conventional artillery technology is expected to become an effective means to deal with future high-end rival large scale missile firepower. The origin of early new concept weapon — Electromagnetic Railgun electromagnetic railgun called electromagnetic rail gun technology concept principle is relatively simple: it consists of two parallel tracks, the projectile sandwiched between two tracks; two rail access to power, the current flow to the projectile to orbit another orbit have a strong magnetic field, magnetic field and current interactions, the Lorentz force powerful projectile, achieve high speed (theoretically to Daya light, it is almost impossible to achieve). It is a typical and unique kinetic energy weapon, which can be used to combat anti-ship missiles, tactical ballistic missiles, surface to air missiles and anti radiation missiles. Electromagnetic railgun is a new concept weapon, but the origin of this invention has been eighty or ninety years of history. The electromagnetic rail gun invented by French vhailor Rupert in 1920. In 1944, Dr. Hensley of Germany developed electromagnetic railgun 2 meters long, 20 mm diameter, the weight of 10 grams of cylindrical aluminum projectile acceleration to 1.08 km / sec; in 1945 he was the 2 door electromagnetic railgun series, the projectile speed reached 1.21 km / sec. During World War II, Japan has also studied the acceleration of electromagnetic railgun, and 2 kg of the projectile speed to 335 M. However, due to the key problems such as material and power can not be solved, the research of electromagnetic railgun is in a bottle neck. In 1978, Australian National University physicist Richard Marshall and John Barber et al use of electromagnetic railgun is 5 meters long, the quality of 3.3 grams of plastic projectile to 5.9 km / sec speed of the successful launch of a breakthrough. After the end of the cold war, with the change of the American and Western defense thoughts, the research focus of the application of the electromagnetic rail gun was shifted from the strategic and the space defense to the conventional war and the tactical application. The United States Army made a focus of technology program (FTP), for about 5 years, will invest $500 million in initial kinetic energy increased to 20 MJ, the velocity reaches 3-4 km / sec, investment of $220 million, making a research prototype and the force is transmitted repeatedly certain; and then two years the test and improvement, enter the full size technology verification phase, the implementation of advanced technology demonstration program, to meet in the air defense, anti missile, anti armor and other weapon system requirements from the research of general weapons. In addition to the United States, Western Europe, Britain, France, Germany, Japan and Russia are involved in the study of electromagnetic railgun technology. The main direction of development of the British electromagnetic railgun is equipped in the future main battle tank. France and Germany decided to jointly develop electromagnetic railgun, plans are divided into.相关的主题文章:
