中国军方证实海军正在海上测试轨道炮



China confirms that are testing an electromagnetic railguns on a navyship.

中国证实正在一艘军舰上测试电磁轨道炮。

Zhang Xiao, associate research fellow atthe Wuhan-based PLA Naval University of Engineering, led a team to developrepeating pulsating direct current power system that could charge the railgun.

张晓，武汉中国人民解放军海军工程大学副研究员，正率领一个团队开发循环浪涌电源系统，为轨道炮提供电源。

The same team solved technical issuesfor shipborne electromagnetic launching systems that will be used on the nextChineses aircraft carrier.

而同一个团队也解决了舰载电磁弹射系统技术问题，该弹射系统将用于中国下一代航空母舰。

China is the first country to mount arailgun on a warship. The PLA landing ship Haiyang Shan, has been photographedwith railgun and was seen undergoing tests at a dock in Wuhan before itsreported sea trail this year.

中国是第一个将轨道炮安装到战舰上的国家。有人拍到解放军登陆舰海洋山号上装备了轨道炮，正停泊在武汉码头即将出海测试。

US is testing a Railgun on land and it can shoot 20-30shots

美国正在陆上测试轨道炮，可射击20-30次

The US Office of Naval Research (ONR), which coordinates technologyprograms for the navy, previously reported that a prototype railgun could firebetween 20-30 shots. But it remains to be seen if the gun can be improved tofire hundreds of rounds in quick bursts.

美国海军研究局（ONR）正在为海军协调技术方案，先前的报道称，原型轨道炮可射击20-30次。但该轨道炮是否能改进达到快速射击数百次，还有待观察。

It will be difficult to make a railgunwhich can be used in military operations
* fire enough shots, fire shots quickly and have the system last for hundredsor a thousand shots
* target the shots that are moving at 5 to 20 times the speed of sound龙
* fit the railgun with its power systems onto a Navy ship

轨道炮用于军事目的还有以下困难
*射击足够的次数，还要快速射击，并且相关系统能够支持数百到数千次射击
*射击速度要达到5-20倍音速
*能够将电磁炮及其电源系统装入一艘军舰

China claims to have solved the powersystem and their latest destroyer has large engines for powering a railgun.China claims that the power system can convert the over one hundred megawattsof power into electricity for the railgun. If the size of systems for a railgunwere large then China could always create mostly dedicated ships as part of afleet. The ships with railguns would protect carriers and be able to launchlong range attacks.

中国宣称已经解决了店里系统，而且他们最新一级驱逐舰有足够的动力驱动轨道炮。中国声称研发的电源系统能将超过100兆瓦的能量转化为轨道炮用电力。如果轨道炮的尺寸较大，那么中国会建造更为专用的军舰作为舰队的一部分。配有轨道炮的军舰能够保卫航母，并且进行远程攻击。

其他中国军事电磁领域的进展

China claims to have successfully testedits first permanent magnet propulsion motor for vessels recently, according tothe State-owned China Shipbuilding Industry Corporation (CSIC), which is known formanufacturing China’s first aircraft carrier and the Jiaolong submersiblevessel.

中国声称最近已经成功测试了第一台船用永磁推进电机，国有的中船重工（CSIC）是中国第一艘航母建造企业，并且建造了蛟龙号深潜船

The motor used in conventionalsubmarines has the power of several megawatts, but he still cannot determinethe exact power of the installed test model.

用于常规潜艇的电机功率约为数兆瓦，但目前仍无法确定安装在测试模型上的电机的准确功率。

Permanent magnet propulsion motortechnology can replace the reduction gears and significantly reduce the runningsound to the lowest possible level, the expert said.

专家指出，永磁推进电机能够替代减速机，将潜艇的运行噪音显着降低至极低水平。

On the global scale, the permanentmagnet motor will have the power to meet the needs of full electrical movementfor nuclear submarines.

在世界范围内，永磁电机能够满足核潜艇的全电推进需求。

In July 2017, Chinese state media hadreported that the China is fitting its newest nuclear sub with anelectromagnetic engine that sounds a lot like Tom Clancy’s fictional RedOctober engine.

2017年7月，中国官媒报道称，中国正在建造的最新型号核潜艇装有电磁推进器，似乎与汤姆克兰西的幻想小说《追击红色十月号》颇有类似之处。

They had also reported that an electric rim driven shaftless submarinepropulsion system was installed.

中国官媒还报道称，该潜艇装备了无轴推进系统。

Rear Admiral Ma Weiming, China’s topnaval engineer, is notably responsible for the development of multiple Chinesenaval electromagnetic programs, including the electromagnetic catapult andrailguns. He said the Chinese navy is adding a “shaftless” rim-driven pumpjet,a revolutionary and silent propulsion system to their newest attack submarine,the Type 095 SSN.

海军少将马伟明是中国顶级海军工程师，负责多项中国海军电磁项目的开发，包括电磁弹射器和轨道炮。他说，中国海军正在其最新的攻击性核潜艇095SSN上装备一种“无轴”泵喷推进器，这是一种革命性的静音推进系统。

This electric drive is an attempt toleap beyond current submarine technology to technology with a long history ofattempted development. This is similar to China making a strongercommitment to develop a submersible arsenal ship. China is taking technologyand designs with decades of history and actually implementing them.

这种推进电机是一种跨越现有潜艇技术的尝试，同时也有着悠久的发展历史。似乎中国正在研制一种强大的导弹潜艇。中国花费了数十年来真正实现这些项目。

Previous submarine pumpjets are“shrouded propellers,” which consist of a tubular nozzle covering thepropeller. By removing the shaft of the propeller, the reduction in the numberof moving parts decreases the noise made by the pumpjet, as well as saving hullspace. Smaller civilian rim driven electric pumpjets are easier to maintain,and have less cavitation (bubbles that form during propeller movement), whichmake them even more quiet.

以前的潜艇泵喷推进器为“罩式推进器”，用环状导管包裹螺旋桨。而中国的泵喷推进器通过取消螺旋桨轴，减少了运动部件数量，降低了泵喷推进器的噪声，同时还节约了潜艇空间。考虑到小型化民用无轴驱动泵喷相当易于维护，而且空泡化现象（螺旋桨运动时形成的气泡）也减少了，这使得该型推进器更为安静。

CCTV13 had a “Focus on the interview”segment on May 30,2017. They discussed the of electric propulsion technologypower of Admiral Ma Weiming. There was some discussion of the technology andspin about how China was moving beyond copying to attempt to createbreakthroughs.The first few minutes of the video discussed telecommunicationswitching work of Zhang Ping.

2017年5月30日，在CCTV13的“焦点访谈”节目与马伟明少将讨论了全电推进技术。节目中有些技术方面的探讨，并讲述了中国如何从复制到努力创新。视频一开始的几分钟讨论了张萍的交换设备的相关工作。（译者注：词有些拗口，不过就是这玩意儿。）

Integrated Electrical Propulsion System(IEPS) turns all the output of the ship’s engine into electricity, unliketraditional propulsion designs, which convert engine and reactor output intomechanical action to turn the propeller shaft. The high electrical output canalso be used to power motors for the propellers or potentially high-energyweapons. Additionally, IEPS has far fewer moving parts, making them quieter,and thus ideal for use on submarines. When coupled with quieter reactors likethe Type 095’s reported natural circulation reactor, the rim-driven pumpjet andIEPS can drastically reduce the acoustic signature of any SSN.

综合电力推进系统（IEPS）将船舶发动机的输出转化为电能，这与传统的推进系统设计不同，后者将发动机和反应堆的输出转化为机械运动，以驱动螺旋桨。而强大的电能输出也可用于驱动螺旋桨或者高能武器。此外，IEPS的运动部件更少，这使得它更加安静，更适合用于潜艇。再加上更加安静的反应堆，比如095型所报道采用的自然循环堆，无轴泵喷驱动器和IEPS能够极大地降低SSN的噪音信号水平。

To people paying attention, the extra$61 billion for defense in the Omnibus Budget is really needed.

对关注者来说，确实还需要额外增加610亿美元的综合预算国防开支。
