研制VASIMR磁等离子体火箭的公司开始发行股票

新闻发布时间:2010-10-11

[本站综合报道]  据哥斯达黎加Tico时代周刊网站近日报道,研制磁等离子体火箭的Ad Astra公司将于2010年10月12日在哥斯达黎加国家股票交易所开始发行股票。


   美国麻省理工学院毕业的磁等离子体物理学博士、NASA前宇航员张福林(哥斯达黎加裔)于1979年在美国麻省构想了VASIMR(可变比冲磁等离子体火箭)。他在1980年被选为NASA宇航员,此后25年间曾7次到国际空间站执行任务,同时在NASA作为等离子体物理学家继续研究VASIMR。2005年从NASA退役后。他成立了私营的Ad Astra 火箭公司(一间实验室基于休斯顿,另一间实验室在他出生的哥斯达黎加)。NASA于2005年与Ad Astra火箭公司签署协议,把先进的NASA火箭概念(VASIMR)转移给Ad Astra火箭公司并使其商业化。

  据太空飞行网站早些时候报道,私有化后5年时间里,随着资金的注入量加大,VASIMR的技术成熟度(TRL)从2提高到了6,现在正在向技术成熟度7级迈进。而私有化前的25年时间里,VASIMR的技术成熟度才从0提高到2。奥巴马政府建议取消星座计划、让NASA集中精力孵化太阳系探索用的新技术。这使得VASIMR被放在了聚光灯下。

Ad Astra火箭公司 的主营项目就是VASIMR。按照张福林的说法,VASIMR要去执行的飞行任务将比普通化学火箭推进的花费少20倍。VASIMR的第一项任务是去清扫太空垃圾。卫星上天后工作一些年就会失去电源并停止发挥作用,却仍然在轨道上飞行,太空里积存的越来越多这样的废弃卫星,增加了碰撞的几率。张福林的项目就是要减少废弃卫星的数量,方法之一是在国际空间站上给它们加注燃料,方法之二是把它们撞下到地球大气中烧掉,方法之三是把它们推向太阳焚毁。

Ad Astra目前正在与NASA合作,准备于2013年在国际空间站上对VASIMR进行试验。如果一切照计划进行的话,2014年VASIMR将开始商业化应用。联合国正在考虑建立法规,对一些发射卫星却没有打算在卫星失效后进行妥善处置的国家或者公司课以罚款。届时,张福林的火箭拟进行的清扫服务将迎来可观的客户。这一市场目前正在开始浮出水面,已有几家公司对这种清扫服务表示了兴趣,张福林说,一切都将由市场驱动。这种服务不会很便宜。发射卫星的成本大约在1.5亿到2亿美元,清扫废旧卫星的成本估计得是这个额度的几分之一。

张福林的VASIMR还打算用于深空太空飞行任务,包括火星旅行。张福林认为他的等离子体火箭可以把去往火星的飞行时间缩短到大约40天。

VASIMR® is not suitable to launch payloads from the surface of the Earth due to its low thrust to weight ratio and its need of a vacuum to operate. Instead, it will function as an upper stage for cargo, drastically reducing the fuel requirements for in-space transportation. The engine will perform the following functions at a fraction of the cost of chemical technologies:

•Drag compensation for space stations
•Lunar cargo transport
•Human transportation to Mars
•In-space refueling
•In-space resource recovery

不错了,当初那个50KW的VX-50,推力只有0.5牛。
VX-200发动机200千瓦5牛推力,效率比其他的如深空一号的NSTAR Ion Engine低一些,那个是2.3千瓦0.092牛,换算的话200千瓦能到8牛推力。当然发动机放大效率不会不变,而不同类型发动机效率本来就不一样,不过可以做一个大致参照,VASIMR做的更大效率也不会有成倍的上升

In December, Ad Astra signed a thirdextension of its 2005 Space Act Agreement with NASA to place the VF-200-1, aprototype of the Vasimr engine, on the International Space Station in early2016 for its first in flight characterizations. However, a new series ofin-house studies are looking at commercial markets well beyond, includingregular resupply of a human lunar orbiting base if U.S. policy makers opt tomove in that direction.

Chang-Diaz, a plasma physicist and formerNASA astronaut, has worked on Vasimr for more than three decades. Sinceshepherding the initiative from the Massachusetts Institute of Technology andNASA to the private sector in 2005, the seven-time shuttle mission veteran andhis colleagues have developed an argon-fueled, 200-kw prototype, the VX-200,which has undergone more than 10,000 test firings in Ad Astra’s suburban Houstonvacuum chamber and demonstrated an efficiency exceeding 70%. The company plansto follow work with its first flight prototype on the ISS with an orbitingfree-flyer demonstrator, the VF-200-2, near the end of the decade.

  推迟多年的PDR终于显身了:
  ----------------------------
   
AD Astra火箭公司达到重要的设计评审里程碑(PDR)
Ad Astra Rocket Company reaches importantdesign review milestone
Published by Klaus Schmidt on Sat Jun 29,2013 5:41 pm via: Ad Astra


[Houston, TX] – After more than a year ofplanning and preparation, a team of Ad Astra engineers and physicists, alongwith NASA engineers participating as part of a technical interchange, completedthe company’s first formal preliminary design review (PDR) of the VF-200engine. The 200 kW “proto-flight” is the company’s first engine planned to betested in space. The review was conducted on Wednesday, June 26, 2013 at AdAstra’s research facility near Houston, TX.
[休斯敦,TX]  - 经过一年多的规划和准备,一个ADAstra的工程师和物理学家团队,与NASA工程师们一起参加了技术交流合作的一部分,完成了该公司VF-200发动机的第一个正式的初步设计评审(PDR)。 200千瓦“样机飞行”是该公司的第一个计划在太空进行测试引擎。2013年6月26日周三在德克萨斯州休斯敦AD Astra的研究设施附近进行了评审,。


The PDR incorporates the collectiveengineering knowledge gained over several years from the VX-200 experimentalprogram as well as multiple conceptual design studies carried out by the AdAstra team. All major VF-200 subsystems were reviewed, with special focus beingplaced on the thermal steady-state rocket core design. The thermal steady state– the capability of the rocket to maintain a stable temperature for extendedperiods of time – is to be initially tested in early 2014 with long-durationplasma firings, using Ad Astra’s existing facilities and the VX-200SS (steadystate) device. The VX-200SS is a modified version of the VX-200, and it iscurrently under construction at Ad Astra’s Texas facility.
该PDR采用了集体工程获得的知识,几年来从VX-200实验程序,以及由AD Astra团队开展的多个概念设计研究。 所有主要VF-200的子系统(被)进行了审查,特别关注了一个被放置在热稳定状态火箭核心的设计。热稳定状态  - 一个火箭的能力,去长时间保持稳定的温度  - 2014年年初,(将)运用AD Astra现有的设施和VX-200SS(稳态)设备,初步测试持续的长时间等离子点火 VX-200SS 是一个修改版的VX-200,它目前正在AD Astra的得克萨斯州工厂建造。


The PDR is the first of a sequence ofestablished design milestones and design reviews of the “proto-flight” hardwareat increasing levels of detail. Successful completion of the design and testplans developed in this process will lead to the next, critical design processbeginning in mid-2014. During Wednesday’s review, all of the key subsystems ofthe VF-200 engine and their respective interfaces were presented, defined andintegrated in a revision-tracking documentation tree, which will become theformal repository of all the design data for the system. The documentation treehas been developed to capture the design specifications, program management,safety, and reliability aspects of the system. Ad Astra has been working closelywith the NASA team on safety and reliability with respect to generalspaceflight design as well as testing on the International Space Station (ISS).
该 PDR是 在持续提高细节水平的“样机飞行” 硬件上  建立设计的里程碑和设计评审 序列的第一个。在这个过程中开发设计和测试计划的成功完成将导致下一个,(就是2014年中期开始的关键的设计过程在周三的评审期间,VF-200发动机的关键子系统和各自的接口被提交、定义和集成在一个版本的跟踪文档树内,这将成为系统正式的所有的设计数据的存储(仓)库。该文档树已经发展到去(捕捉得到)一个设计规范、项目管理、安全、和系统的可靠性方面。 AD Astra就一般航天设计以及安全性和ISS可靠性测试,一直与 NASA团队紧密合作。

高科技的VASIMR火箭发动机可以解决火星旅行、太空垃圾以及更多的(问题)
High-Tech VASIMR Rocket Engine Could Tackle Mars Trips, Space Junk and More
November 19, 2013 07:01am ET

Scientists are making progress on an advanced space propulsion system aimed at a variety of uses, including reboosting space stations, cleaning up space junk and powering superfast journeys that could reach Mars in less than two months.
在用于多种目的先进空间推进系统上,科学家们正在取得进展,(这些用途)包括提升空间站,清理太空垃圾和提供超快的动力,可以在不到两个月的旅程时间内到达火星。
                    


Led by former NASA astronaut Franklin Chang-Díaz, Ad Astra Rocket Co. is developing the versatile, high-tech engine, which is known as the Variable Specific Impulse Magnetoplasma Rocket, or VASIMR for short.
由前NASA宇航员张福林领导的AD-Astra火箭有限公司正在开发一种多功能,高技术的发动机,这被称为可变比冲磁火箭,或简称VASIMR 。
                    


Engine work has been underway for more than 25 years, and is based on NASA and U.S. Department of Energy research and development in plasma physics and space propulsion technology. Commercializing the VASIMR electric propulsion engine is the flagship project of Ad Astra, which has been in business for nine years and has invested $30 million to date to mature the concept.

这种类型的)发动机的工作已经进行了25年以上,并且是基于NASA和美国能源部 研究开发 等离子物理和空间推进技术。 商业化的VASIMR电推进发动机是AD Astra的一个旗舰项目,已经经营了9年(2013-9=2004),并且迄今投资了0.30亿美元去成熟这个概念。 [超快推进概念(图片)]
           
Ad Astra's Texas headquarters and the company's subsidiary research lab in Costa Rica are full of researchers who are attracted by game-changing, disruptive technology, Chang-Díaz said.
AD Astra的德州总部和 该公司在哥斯达黎加的附属研究实验室 ,(凭借)改变游戏规则的、颠覆性的技术吸引了全部研究人员,长迪亚斯说。
                  
"So, we tend to have a very young team, and they get younger and younger," said Chang-Díaz. "I guess that's because I'm getting older. But it reminds me of the way NASA used to be — so I try to look at that as a good sign."
“这样,我们有了一个趋向于非常年轻的团队,并且他们变得越来越年轻“  张福林说。“我想这是因为我年纪越来越大(的缘故吧?)。但它让我想起NASA常用的方式- 所以作为一个好的迹象我要尝试看一看。

近地小行星偏转任务, 基于 AD Astra的 恩托太阳能电力推进航天器,配备有VF -200级别的VASIMR发动机。
               
VASIMR heats plasma — an electrically charged gas — to extreme temperatures using radio waves. Strong magnetic fields then funnel this plasma out the back of the engine, creating thrust.
VASIMR加热等离子体- 一种带电气体 - 在极端温度下使用无线电波。强磁场,然后出发动机的背面漏斗该等离子体,创造推力。
     
The most advanced VASIMR engine is Ad Astra's 200-kilowatt VX-200.
最先进的VASIMR发动机是 AD Astra的 200千瓦VX-200 。
                  
The pathway to the VX-200 was discussed at the 33rd International Electric Propulsion Conference, held at The George Washington University in Washington, D.C., last month. Company officials gave details about a plan to flight-validate another VASIMR variant, the VF-200, on the International Space Station (ISS) in the next few years.
上个月,在华盛顿特区乔治·华盛顿大学举行的33届国际电推进会议上,讨论了通向VX -200的路径。公司负责人详细介绍了有关另一个变种VASIMR 飞行验证计划,VF-200在未来几年安装到ISS上。
                    
Key to this upcoming flight test is an electric-propulsion package called Aurora, which Ad Astra is also developing. Aurora, which carries a VASIMR VF-200 high-powered plasma source, is a commercial test bed that will operate as part of the ISS.
这个即将到来的飞行试验的关键是一个称为极光的电动推进包AD Astra也在开发它。极光,带有一个VASIMR VF-200大功率等离子体源,是一个商业测试床,作为ISS的一部分运做。
         
The major purpose of Aurora is to flight-qualify and test the performance of the 200-kilowatt VF-200 VASIMR engine in the space environment. A battery storage module on the platform stores the energy needed to fire VASIMR at 200 kilowatts for about 15 minutes before needing to be recharged. [Giant Leaps: Top Milestones of Human Spaceflight]
该极光(项目)的主要目的是飞行资格认证,以及测试200千瓦的VF - 200 VASIMR发动机在太空环境中的性能。平台上的一个电池存储模块存储所需要的能量,200千瓦下点火VASIMR大约15分钟 ,然后需要重新充电 [巨大飞跃:载人航天顶级里程碑]

With the Aurora trial looming, is it now showtime for VASIMR?
随着极光实验若隐若现现在是VASIMR的演出时间吗
               
"It is, absolutely — we see that test on ISS as a gateway," Chang-Díaz told SPACE.com. "That's what we're marching to … a demonstration of the VASIMR on the Aurora platform on the ISS."
“是的,绝对的 - 作为一个关键路由我们看到了在ISS上的测试“ 张福林告诉SPACE.com 。“这是我们正在前进的目标... 在ISS的极光平台上VASIMR的一个演示。
                  
Extensive, multiyear ground testing of VASIMR shows no signs of wear and tear on the engine, after more than 10,000 high-powered shots, he added.
进一步说VASIMR多年的地面测试表明,在超过10,000(次)大功率喷射之后该发动机没有磨损和撕裂的迹象他补充说
                  
A Space Act Agreement with NASA enables Ad Astra's commercial testing of advanced electric propulsion and power systems in support of developing space commerce and exploration requirements.
一份与NASA 的太空行动协议 给力AD Astra先进的电力推进系统和动力系统的开发空间商业和探索要求支持的商业测试。
     

"The agreement with NASA is that they will do the integration of the system on the ISS," Chang-Díaz said. "We've been working with the NASA ISS program on finding the right location to place the device … and we found it to be on top of the [station's] Z-1 truss."
NASA的该协议是,他们将在ISS上做系统的整合, “ 长迪亚斯说。“我们一直在与NASA 的ISS计划一起工作,以寻找合适的位置放置该设备,并且我们找到了,把它放在 [该站] Z-1桁架顶部。”
               
The Aurora would be delivered to the ISS by a commercial launcher and robotic transfer vehicle, such as Orbital Sciences' Cygnus vehicle or other commercial delivery spacecraft.
该‘极光’将由 商业发射器和机器人转移运载器 递送到ISS上 ,如轨道科学公司的天鹅运载器或其他商业投递(用)航天器。

Range of applications
应用范围
               
Chang-Díaz said that getting onboard the ISS can happen about three years from now. But doing so will require an infusion of cash — roughly $100 million to prepare the ready-for-flight hardware.
Chang-迪亚斯说,能够使其驻扎在ISS上,从现在起可能大概还要三年(2017但这样做将需要现金投入 - 约为1.00亿去准备就绪型飞行的硬件。
                 
And Aurora would have broader applications as well, becoming a National Plasma Physics Laboratory suitable for performing a variety of studies in space.
同时极光(项目)也将有更广泛的应用,成为一个国家级的等离子体物理实验室,适合在空间进行各种研究。
                     
"We believe this platform can do a lot more than just test the VASIMR," Chang-Díaz said. "It can be used for exploration technology development and demonstration. We also feel we can offer this platform to other electric thrusters that also want to test in space."
“我们相信这个平台可以做很多事情,不仅仅是测试VASIMR ” 长迪亚斯说。“它可以用于探索技术开发和演示。我们还认为,我们可以提供这个平台到其他电动推进器,也想测试空间。
               
Chang-Díaz also outlined a range of applications envisioned for the VF-200-class engine, including the following:
张福林还简要介绍了VF -200级发动机应用设想的范围,包括下列内容:
                     
A commercial low-Earth orbit, high-powered, solar-electric space tug for space-junk cleanup;
商业的低地球轨道,高倍,太阳能电 太空拖船太空垃圾清理;
     

Service and support to satellites — such as refueling, repair and repositioning operations — could be enabled by a high-powered VASIMR solar-electric tug;
服务和支持卫星 -如加油,修复和重新定位业务 -可以 给力与高倍VASIMR太阳能电动拖船;

Chang-Díaz is a record-holding veteran of seven space shuttle flights and three spacewalks carried out between 1986 and 2002.
张福林是一个拥有七次航天飞机飞行纪录保持者的老兵, 1986年和2002年之间进行了三次太空行走。
               
"For me, going to Mars was, of course, a dream — a dream of every astronaut," Chang-Díaz said. However, his trips into Earth orbit have somewhat modified and tempered his approach to space.
对于我来说,去火星,当然,一个梦想一个每个宇航员的梦想长迪亚斯说。无论如何,他进入地球轨道的旅行有所修改,并锻炼了他实现途径(接近方法)到太空。
   

"I was not quite as aware of the limitations of speed that we actually have in space to get to Mars," he said. "I became very aware that sitting in a spacecraft for a year going to Mars was not going to be pretty. Space is very inhospitable. When you don't have electricity, it gets cold. You are in the middle of nowhere. When you're on your way to Mars, it's like you are flying on a cannon ball. You have no choice but to go there, even if you don't have the oxygen to get there."
我是不太知道速度的局限性,我们其实有在太空去火星
他说。我变得很清楚,坐在航天器一年没有去火星将是相当。空间是非常荒凉。当你没有电,天气变冷。您现在的蛮荒之地。当你用自己的方式去火星,这就像你大炮球飞。你没有选择,但去那里,即使你没有的氧气到那里。


Taking that long-haul approach to planting feet on Mars is a nonstarter, Chang-Díaz said. "I think we need to give the astronauts a fighting chance. That's why I believe we ought to do the technology development before we keep talking about Mars."
考虑,长途接近方法)在火星上种植脚是一个微乎其微的,长迪亚斯说。我认为,我们需要给宇航员战斗的机会。这就是为什么我相信我们应该做的技术开发之前,我们一直在谈论火星。


Using a VASIMR engine to make a superfast Mars run would require incorporating a nuclear reactor that cranks out megawatts of power, Chang-Díaz said, adding that developing this type of powerful reactor should be high on the nation's to-do list.
VASIMR发动机到做出超快火星的运行出兆瓦的电力,就需要把一个核反应堆,曲柄,长迪亚斯说,加入强大的反应堆,发展这种类型应该是高国家的to-do列表。

As for advancing technologies, Chang-Díaz said to keep an eye on superconductivity work.
对于先进技术,张福林说要对超导工作保持关注。
                       
"Superconductivity is something that has enabled us to build the magnet that we now have," he said. "But the field is rapidly developing into more powerful magnets and lighter-weight magnets, so I think some day, the magnetic fields that we will be able to use are going to be much higher than the ones that we are using now — and that will enable us to go to much higher temperatures and densities on the plasma."
超导是有给力我们建立,我们现在有磁铁,的一些事情”  他说。但是,该领域正迅速发展成为更强大的磁铁和重量更轻的磁铁,所以我觉得有一天,的磁场,我们将能够使用将要远远高于那些我们现在所使用的 - 那给力我们去对等离子体的温度和密度高得多。


That raises the futuristic specter of nuclear-fusion rockets, which could open up the entire solar system to exploration, Chang-Díaz said.
这引发核聚变火箭未来的幽灵,这可能打开了整个太阳系探索,长迪亚斯说。


Although these possiblities are exciting, "we don't want to get too far ahead of ourselves," he cautioned. "Otherwise, people begin to put us into the science-fiction category, and we don't want to be there. We want to be here and now."
虽然这些可能性是激动人心的,我们不希望自己过于超前,他警告说。否则,人们开始把我们的科幻类,我们不想在那里。我们想在这里和现在。

    导读美国艾德-阿斯特拉火箭公司最新研制一种“VASIMR”火箭发动机可使未来火箭之旅缩短至两个月之内,还可用于重启国际空间站。
     

腾讯科学(悠悠/编译) 据国外媒体报道,目前,科学家正在致力研制先进空间推进系统,艾德-阿斯特拉火箭公司张福林研制一种通用型高科技“VASIMR”火箭发动机可使未来火星之旅缩短至两个月之内。
VASIMR的全称是“可变比冲磁等离子体火箭发动机”,张福林是美国宇航局前任宇航员、麻省理工学院华裔物理学家,商业化VASIMR电子推进发动机是艾德-阿斯特拉火箭公司的旗舰项目,已研制9年时间,共投资3000万美元。
VASIMR系统使用无线电波将氢、氦等燃料加热转化为超高温度等离子气体,温度可达到1100万摄氏度,较强的磁场将等离子体气体从发动机尾部排气管释放出来形成推进力,推动太空飞船的快速飞行,预计采用VASIMR系统可使太空飞船最高速度达到55公里/秒,这样有望实现两个月之内从地球抵达火星。此外,使用等离子燃料还可在航天器周围形成磁场,避免太空辐射造成的危害。
最先进的VASIMR发动机是艾德-阿斯特拉公司制造的200千瓦VX-200。艾德-阿斯特拉公司计划未来几年内将在国际空间站装配另一款VASIMR系统发动机——VF-200

真的太廉价了,3000万对NASA来说就是点零花钱!为毛天朝总是想做烧钱的大火箭呢?CZ-5低轨运载能力已达到25吨了,稍将轨道提高到1000公里,也还有20吨吧,再用太阳能电推转移至环月轨道 ,只需要低轨两次对接,环月一次对接就可以了,超过35吨载人登月配置了吧。
