美公司公布实验性航天飞机概念外观图

新华网8月25日电 据美国科技博客Gizmodo报道,近日,美国诺斯洛普·格罗门公司公布了实验性航天飞机XS-1的概念外观图,并强调称这一项目“不算太贵”,也可以“像普通飞机”那样运行。

七月中旬,美国国防部高级研究计划署(DARPA)同波音公司、马斯腾太空系统公司和诺斯洛普·格罗门公司签署了未命名的航天飞机合同,开发一种能在上大气层里可以像普通飞机那样轻易飞行的超音速航天飞机。

本周诺-格公司公布了XS-1的概念图。根据计算,这款航天飞机必须以10倍或以上音速的速度飞行,10天内可以飞行10次,装载3000-5000磅货物(约合1360-2270公斤),同时每次任务的成本不高于500万美元。

诺-格公司宣布将与子公司“缩尺复合材料”(Scaled Composites)及维珍银河公司合作。诺-格公司的发布显示,XS-1将使用可重复使用的推进器以达到“不贵”和“像普通飞机”那样运行的要求。推进器将成为第一阶段研究的核心部分,研究方向包括低成本、能复原等等,远期目标则包括卫星部署和送货入轨等任务。

诺-格公司还称,飞机将使用运输-起竖-发射车(TEL)进行发射,减少地面组成员,使用自动的飞行控制系统,并像普通飞机那样水平降落。而维珍银河公司则将为其提供商业方面的帮助。

Northrop Grumman Shows Off Its Experimental Spaceplane Concept

In mid-July the Defense Advanced Research Projects Agency (DARPA) awarded contracts to Boeing, Masten Space Systems, and Northrop Grumman to develop an unmanned spaceplane to travel hypersonic speeds in the upper atmosphere—as easily as a commercial airliner.

This week we got to see what Northrop Grumman's vision of such a spacecraft would look like. Working with Scaled Composites, an aerospace company owned by Northrop Grumman, and Richard Branson's Virgin Galactic, the XS-1 (which means experimental spaceplane) must travel Mach 10 or higher, travel 10 times in 10 days, and carry 3,000 to 5,000-pound payloads for less than $5 million as per DARPA's rules.

A press release details that the XS-1 will have a reusable booster that Grumman stresses is "affordable" with "aircraft-like" operations. This first stage looks to be at the heart of the design as the team says the booster enables "new generations of lower cost, innovative, and more resilient spacecraft." The upper stages of the aircraft will help deploy satellites and other possible payloads into orbit.

"We plan to bundle proven technologies into our concept that we developed during related projects for DARPA, NASA, and the U.S. Air Force Research Laboratory," said Doug Young, a vp with Northrop Grumman, in an official statement. So it seems Grumman will be pulling from its portfolio of projects to meet DARPA's lofty goals.

Landings and takeoffs will also need to be as efficient (if not more) than the spaceplane's fuel-guzzling appetite. Grumman says it'll use a transporter erector launcher(!), minimal ground crew and autonomous in-flight systems. On its return trip, the XS-1 will land horizontally, just like your everyday 747. Branson's Virgin Galactic will offer a majority of its expertise helping with XS-1's commercial operations. Boeing is also getting a little commercial spaceflight help from Jeff Bezos' company Blue Origins. We won't get to see the products of these companies' combined efforts until DARPA holds its phase 2 competition sometime in 2015. And a few years after that we'll see the first spaceplane mission launch.
