New Chinese Military Developments

Re: new close in multi porpose anti aircraft gun

I think this weapon system can be remote operated and manual fired. If you notice there is an integrated optical system on top and it could be linked to the fire control system. It seems that it does not have an independent tracking system.

There is also a plus to making this system switchable from remote to manual if the fire control system is down the crew can man the gun and stay in the fight.

What ship is this weapon being mounted on?

The chinese post claimed it be a electronics surveillance ship.

罕见：中国部分电磁炮及电磁装甲曝光！z

--------------------------------------------------------------------------------

　　中国的一个有趣的课题是在哈尔滨工业大学(Harbin Institute of Technology)的使用线圈炮(coilgun)的装甲。现代坦克的装甲由一层高爆物质夹在两层金属板组成;当击中时高爆物质爆炸，进而摧毁像 shaped changes 之类的常规武器。

　　中国的装甲将比这种反应装甲更进一步。它用传感器侦察到来袭的炮弹之后，线圈炮 (coilgun)抛出一片装甲在炮弹打到坦克之前阻断它。这种方式的一个问题就是发射物不能含铁，因为线圈炮的脉冲磁场会加热铁，而不是加速它。哈尔滨的研究者们试验了其他金属比如铝，但是发现它太容易融化了，而且作为装甲来说太弱。根据一篇最近文章，在他们的钢装甲与铝线圈的实验中发现“来袭炮弹的冲击力不仅没减弱反而增加了一点”。

　　美国类似电装甲的实验是保密的，所以知道中国这些也是可观的。费尔(Fair)注意到，不管什么原因，中国的研究者对他们自己的研究出奇的公开.

　　最 近的一期IEEE Spectrum 上有一篇关于电磁发射的文章：For Love of A Gun, by Carolyn Meinel。其中有一段关于中国的，翻译出来献给大家。

　　如果麦克廓蔻(McCorkle)看得广一点，他可能会与中国河北炮兵工程学院的王英相遇。早在1981年，王英阅读了费尔(Fair)的第一届电磁发射学术会的论文集并决定把这一课题作为他的终身研究方向。开始时支持他的人很少，但在过去十年以来他和他的学生们在中国的22个学校和军事研究所建立了电磁发射的研制机构。他和瑞扯-玛绶(Richard Marshall)合写了关于这一课题的两本教科书。

　　实际上玛绶(Marshall)和费尔(Fair)很高兴能在中国找到相同志向的学者。在2004年九月大连理工大学(Dalian University of Technology)的中国电磁发射学术大会上，费尔(Fair)的专题演讲赢得了全场起立鼓掌。会后大连电机系主任带他参观了他们的线圈炮 (coilgun)试验装置。现在中国可能是美国境外最大的电磁炮研究中心。在2006年五月德国Potsdam的第13届国际电磁发射学术大会上，中国出了52篇论文，仅次于美国的72篇。

coil gun or "rail gun" was part of ronald reagan star war program, but it abandone.according to the BBC documentary, several engineers claim that the technology far more suited to tactical,rather than strategic.
one draw back ,is that when fire the gun,the rail will be hot,that it actually melt the rail.making it unusable.

Re: new close in multi porpose anti aircraft gun

I think its a good idea. Just like commercial airliner plane, it can go on auto pilot mode but once sometime not right. He just need to overwrite the auto mode and go manual.

But I think the gunner need to take high G to be one of the criteria. lol.

Re: electromagnet rail gun

A friend of mine actually made a small railgun-type device for a school project. So the technology is certainly feasible.

Re: electromagnet rail gun

didn`t the US Navy has some working prototype on their vessel installed?

Re: electromagnet rail gun

There is a group of people in the UT ece department who are working on a railgun right now so I think at least the U.S. government is very interested in the development of railguns.

Re: electromagnet rail gun

I know quite a number of naval enthusiasts who would love to see the return of battleships via the railgun.

Re: electromagnet rail gun

I wonder what is the advantages of a rail gun. Also I have read about the coil gun structure, which I think is also quite valid.

Can anyone update me in the advantages and disadvantages of both the Rail gun and the coil gun and their practicality.

Re: electromagnet rail gun

The railgun could propel projectiles to higher speeds than conventional firearms and doesn't require powder. The latter is especially important for naval ships in which space and fire safety are top concerns.

Most people are not aware of the difference between railguns and coilguns. The "railguns" in the game Halo, for example, are better classified as coilguns since the projectiles are not in contact with the "rails". In an railgun the projectiles are in contact with two parallel metallic "rails" in which the current could run and the projectile itself conducts electricity. The lorentz effect causes the projectile to move forward with great speed. The coil gun utilizes a series of coils instead. When a current passes through the coils a magnetic field is generated in the middle of the coil (kinda like the transformer) and the projectile is launched forward.

The main problem with both rail and coil guns right now is the power consumption. I believe some devices are in the range of megawatts. Since railgun rounds come in contact with the barrel the rail gun also generates tremendous wasteheat every time it fires a round. This also means that the barrel will wear out faster than conventional guns.

Hopefully that helped.
