[2023-08-31]SCMP评论区：中国海军正在测试地球上最强大的电磁炮

The Chinese navy is reportedly testing the planet’s most powerful coil gun – a type of electromagnetically powered weapon capable of launching projectiles with very high speed and accuracy.
In a firing test revealed to the public for the first time, the electromagnetic launcher accelerated a 124kg (273lbs) projectile to a speed of 700km/h (435mph) in less than 0.05 seconds, according to scientists involved in the project.

据报道，中国海军正在测试地球上最强大的电磁炮——一种电磁动力武器，能够以非常高的速度和精确度发射炮弹。
据参与该项目的科学家介绍，在首次向公众展示的发射试验中，电磁发射器在不到0.05秒的时间内将一枚重达124公斤(273磅)的炮弹加速到时速700公里(435英里)。

It was the heaviest known projectile to be used in a coil gun experiment. While the exact dimensions and maximum range of the weapon remains classified, a shell moving at such speeds could hit a target several kilometres away.
Coil guns are also known as Gauss guns or magnetic accelerators. The weapon features a series of coils arranged along the barrel of the gun, each one constituting a “stage”. Each coil is energised one after another to create a magnetic field that can levitate and propel a projectile forward.
The projectile typically stays suspended in the centre of the coil during launch, which helps to keep it on a straight course and prevent it from touching the wall of the barrel. It can be fired repeatedly and rapidly without causing wear on components.

这是用于电磁炮实验已知最重的炮弹。虽然这种武器的确切尺寸和最大射程仍然是保密的，但是以这种速度运动的炮弹可以击中几公里外的目标。
电磁炮也被称为高斯炮或磁加速器。该武器的特点是一系列的线圈沿炮管排列，每个线圈构成一个“级”。每个线圈一个接一个地通电，产生可以悬浮和推动弹丸前进的磁场。
在发射过程中，炮弹通常悬浮在线圈的中心，这有助于使其保持直线运动，并防止其接触炮管壁。它可以重复和快速发射，而不会对组件造成磨损。

Coil guns could revolutionise the way that wars are fought, allowing for faster, more accurate and devastating attacks on enemy targets. They could also launch missiles or send satellites into space.
The technology has been around for decades, but challenges in materials science and electronics have made it difficult to build large and powerful models.
One of the closest competitors to the Chinese coil gun, a 120mm-calibre electromagnetic coil mortar test device at the Sandia National Laboratories in the United States, can fire a projectile weighing 18kg. It is among the largest of these devices ever built.
Other systems around the world typically can fire projectiles weighing only a few grams and with a diameter of a few millimetres, according to a study published by Israeli scientists in the journal Scientific Reports in January.
The larger a coil gun, the better its ability to fire projectiles similar to those fired by traditional artillery. A standard 155mm artillery shell used by the US military weighs around 43kg, while Italy’s Indigo anti-aircraft defence missile weighs 120kg.

电磁炮可能会彻底改变战争的作战方式，使其能够更快、更准确地对敌方目标进行毁灭性的攻击。他们还可以发射导弹或向太空发射卫星。
这项技术已经存在了几十年，但是材料科学和电子学方面的挑战，使得建造大型和强力的模型变得困难。
美国桑迪亚国家实验室的120毫米口径电磁炮测试装置是与中国电磁炮最接近的竞争对手之一，它可以发射重18公斤的炮弹。它是有史以来建造的最大的此类设备之一。
根据以色列科学家1月份在《科学报告》杂志上发表的一项研究，世界各地的其他系统通常只能发射重量几克、直径几毫米的弹丸。
电磁炮越大，其发射类似于传统炮弹的能力就越强。美军使用的标准155毫米炮弹重约43公斤，而意大利的靛蓝防空导弹重约120公斤。

The coil gun has a number of advantages over traditional artillery, including higher launch speeds, lower launch costs and shorter preparation time, according to the Chinese team led by professor Guan Xiaocun with the Naval University of Engineering.
“It has the potential for revolutionary breakthroughs in terms of speed, range, power, accuracy, safety, flexibility and reliability,” Guan and his colleagues wrote in a paper published in the peer-reviewed journal Transactions of China Electrotechnical Society this month.
“It is widely applicable in areas such as weapon systems, near-Earth satellites and high-speed missile launches.”

据中国海军工程大学教授关晓存领导的中国研究小组表示，电磁炮相对于传统火炮有许多优势，包括更快的发射速度、更低的发射成本和更短的准备时间。
“它在速度、射程、功率、精度、安全性、灵活性和可靠性等方面具有革命性突破的潜力，”关晓存及其同事在本月发表于同行评议期刊《中国电工学会会报》的一篇论文中写道，“它广泛应用于武器系统、近地卫星和高速导弹发射等领域。”

Their 30-stage coil gun is still in the testing phase, and it is unclear when or if it will be deployed in the field. However, the Chinese military has been investing heavily in the technology in recent years.
“The Naval University of Engineering has overcome a series of difficulties” in building a large coil gun, said Ma Weiming, lead scientist of the Chinese military’s electromagnetic launch programme in a paper published in June.
Ma said the challenges included the design and manufacturing of large-calibre high-magnetic-density coils and compact pulsed power technology.
He added that China was developing an even more powerful coil gun capable of launching a projectile at a speed of 3,600km/h, which could push the weapon’s kill range to over 100km.

他们的30级电磁炮仍处于测试阶段，目前还不清楚何时或是否会在现场部署。然而，中国军方近年来一直在大力投资这项技术。
中国军方电磁发射计划首席科学家马伟明在今年6月发表的一篇论文中表示，海军工程大学在制造大型电磁炮方面“克服了一系列困难”。
马伟明说，这些挑战包括设计和制造大口径高磁密度线圈和紧凑型脉冲功率技术。他补充说，中国正在开发一种更强大的电磁炮，能够以每小时3600公里的速度发射炮弹，这可以将该武器的杀伤范围扩大到100公里以上。

The rapid development of coil guns in China was in part due to a breakthrough in sensor technology, according to Guan’s team.
Coil guns generate a strong magnetic field when fired, which can interfere with electronic devices and sensors, so research on electromagnetic launchers typically requires measuring the projectile’s flight behaviour through external means.
However, Guan’s team came up with a new smart projectile equipped with sensors that are shielded from electromagnetic interference thanks to special materials, allowing them to collect high-quality data about projectile flight behaviour. This precise data from internal sensors can help scientists improve the efficiency and stability of coil guns.

根据关晓存团队的说法，中国电磁炮的迅速发展在一定程度上是由于传感器技术的突破。
电磁炮在发射时会产生强大的磁场，这会干扰电子设备和传感器，因此电磁发射器的研究通常需要通过外部手段测量炮弹的飞行行为。
不过，关晓存团队研发出了一种新型智能炮弹，该炮弹配备了由特殊材料制成的可屏蔽电磁干扰的传感器，使他们能够收集有关炮弹飞行行为的高质量数据。这些来自内部传感器的精确数据可以帮助科学家提高电磁炮的效率和稳定性。

没必要猜测，新闻上都有报道。至少在高超音速滑翔导弹方面，美国在过去 8 年里总共进行了 5 次测试，其中 3 次失败。而今天，美国仍无法发射其高超音速滑翔导弹，而中国已经开始生产第二代高超音速武器，该武器基于斜爆震技术，可将导弹提升至16马赫，不是在最后阶段，而是在整个飞行过程中。

When China reveals the testing to the public it means it has already been installed on their naval vessels ready for action. US has to factor this new toy in their computer war games. - UP: 28

当中国向公众公布测试结果的时候，就意味着它已经安装在海军舰艇上了，随时可以投入使用。美国不得不在其电脑战争游戏中考虑到这一新玩具。

Very impressive, but its short range gives it limited usage, for now. - UP: 11

非常令人印象深刻，但是它的射程较短，目前使用有限

0 This coil gun can be used to launch missiles . Currently a missile is launched with its own rocket firing and takes sometime for it to reach optimal speed. This coil gun can accelerate the whole process. It is like launching fighter jets on an aircraft carrier .The advantage is before the enemy can track and fire the anti missile the incoming missile is at the doorstep. - UP: 16

这种电磁炮可以用来发射导弹。目前，导弹是通过自己的火箭发射，需要一段时间才能达到最佳速度。这种电磁炮可以加快整个过程。就像在航母上起飞战斗机。优点是在敌人跟踪并发射反导弹之前，来袭的导弹就在门口
