High-speed 'space wedge' on track

By Jonathan Amos Science correspondent, BBC News, Paris


IXV The IXV would be launched atop a Vega rocket


The European Space Agency (Esa) is pressing ahead with its re-entry demonstrator known as the IXV, which it expects to launch in 2013.

This distinctive wedge-shaped vehicle will be put at an altitude above 400km from where it will begin its flight back to Earth.

Its suite of sensors should give engineers new insights into how objects fall back through the atmosphere.

Ultimately, the data should inform better spacecraft design.

Even probes sent to land on other worlds like Mars should benefit from the knowledge.

&quot;IXV is providing Europe with important technologies and a step to more ambitious programmes in the future,&quot; said Antonio Fabrizi, one of Esa's senior directors.

He signed an agreement at the Paris Air Show that will lead to manufacture of the demonstrator by Thales Alenia Space in Italy.

The company's facility in Turin has spent the past two years researching the concept.

The Intermediate Experimental Vehicle (IXV) is a car-sized, two-tonne automated craft that can be seen as a follow-on to the Advanced Re-entry Demonstrator flown by Esa in 1998.

But whereas ARD was a traditional cone-shaped object, IXV is very different; it has flaps and thrusters to control its descent trajectory. A ceramic heatshield on its underside will prevent IXV from burning up.

The vehicle will launch from French Guiana in South America on Esa's forthcoming small rocket, Vega.

The top stage of Vega will put IXV on a sub-orbital trajectory around the Earth that will bring the demonstrator down in Pacific. A parachute will be deployed to bring it to a gentle splash-down. The whole mission should last about an hour.

The knowledge gained from the flight is expected to feed into materials research and the computer models that are used to describe the energetic physics that occurs when an object plunges through atmospheric gases at several kilometres per second.

Europe's expertise on re-entry technologies is more limited than, say, the US, and it is looking to boost its knowledge with a number of flight demos.

Later this year Esa will also launch its EXPERT (eXPErimental Reentry Testbed) vehicle.

This is smaller than the IXV at just over 1.5m in length and weighing slightly less than 450kg; but again, it will be packed with sensors.

EXPERT will launch to just over 100km on a submarine missile before falling back to the ground and landing by parachute.

Thales Alenia Space is also leading this project industrially, too.

&quot;We are growing a competency in re-entry in our company and this will feed into future missions,&quot; Luigi Pasquali, the president and CEO of Thales Alenia Space (Italy), told BBC News.

Although only one flight of the IXV is currently planned, its recovery from the ocean would allow further experimental flights to be conducted.

谁翻译一下
那我就什么都不发好了。
现在这论坛似乎有个习惯,凡是发TG搞不出来的东西,就会被减分。这估计就是TG搞不出来的原因吧。超大用不了多久就会跟铁血一样了吧!

嗯?不是早就一样了么....
支持斑竹维护论坛秩序
谁能给个大致的意思


欧空局正加紧其返回舱验证机「IXV」的进程。它预计于2013年发射。

这个与众不同的楔形飞船将被送到400km的高度,然后开始返回地面,飞船上的感应器将跟踪收集其穿越大气层时的各种数据。这些数据最终会使未来的飞船设计受益,甚至对送往其他星球——比如火星——的探测器也有帮助。

「IXV将为欧洲提供重要的技术,是我们实现雄心壮志的路上走出重要一步。」欧空局的高级官员安东尼奥-法布里奇说。在巴黎空展上,他与TAS(泰雷兹阿莱尼亚宇航公司)的意大利分公司签署了制造该验证机的合同。该公司位于都灵的设施在过去两年中一直在研究这个项目。

IXV(「中型试验飞船」的缩写)与汽车大小相仿,重约2吨。这个无人飞船可以被视为欧空局1998年发射的ARD(「先进返回验证机」)的后续。不过ARD是个传统的圆锥形飞船,而IXV则很不一样:它机身上有机翼和推进器可以调控其下坠的路线。机身底部的陶瓷防热罩则能防止IXV在返回时烧毁。

IXV将在南美洲的法属圭亚那由欧空局计划中的小型火箭Vega发射。IXV将被置于Vega火箭的上面级,被送往次轨道开始返回,溅落在太平洋。在下落时会有降落伞减速。整个任务预计持续大约一小时。这次飞行收集到的信息将有助于材料研究,并用于设计描绘物体以几公里每秒的速度在大气层中下坠时的能量物理的计算机模型。

欧洲在返回技术上的经验比美国等先行国家要浅得多,因此他们希望通过多次验证飞行来扩充相关知识。

今年(2011)晚些时候欧空局还将发射EXPERT(「实验性返回飞船」)。它要比IXV小,长度超过1.5米,重量不及450千克;它身上也会布满感应器收集信息。EXPERT将由一枚潜射导弹发射到刚刚过100千米的次轨高度,然后开始下坠,并伞降地面。该实验飞船也是由TAS公司领衔制造。「我们公司在返回式飞船领域的能力正逐步提高,这对欧洲未来的太空任务会有很大帮助。」TAS公司的总裁兼CEO路易吉-帕斯夸里对BBC新闻说。(幽幽子补充:EXPERT预计于今年内由一枚Volna火箭从俄罗斯潜艇上发射,Volna火箭即R-29R潜射弹道导弹)

虽然目前欧空局只计划了一次IXV飞行,但等任务结束,从太平洋回收回来以后,或许还会有进一步的实验飞行。

这个是文章里提到的EXPERT的造型。

任务简介动画:

[WARNING! WARNING!] http://www.esa.int/images/4_3_L,118.swf
对于EXPERT,干嘛非要从潜艇上发射,摆酷么?其实论起退役导弹的废物利用,陆基导弹也有一大票。
能把450千克载荷打倒100公里次轨的导弹不要太多。其实法国自己退役的导弹也应该能用,为什么非要花钱找毛子呢?其实用自己的火箭、自己的发射器,搞研究比用别人的方便自在。难道说毛子要的服务费低的令人发指?

着陆场不好找
R-29R的寿命也该到了,这样发射掉也好……

感觉什么像航天飞机啊
欧洲的载人航天是航天飞机还是宇宙飞船啊,这个什么像航天飞机啊

这个确实不好找。也就瑞典北部还好些吧,我记得日本摔航天飞机(模型)就是在瑞典。对于亚轨道测试其实瑞典也差不多够了。还有就是在新喀里多尼亚建试验场,借澳大利亚的地方降落,也是一种选择。另外,原来法国进行弹道导弹试验的时候靶场设在什么地方?

当然,毛子价格低廉,服务到位的话,也是好用的。
