蓝源这家伙的,没有nasa赞助也照样发展航天飞船?到底为了什么?

Jeff Bezos的钱比Musk要多得多,但是他的重点是Amazon,Blue Origin有点玩票的性质,就像去年打捞Apollo 11号的F-1引擎一样。

Blue Origin也在搞液氧甲烷引擎?MCT的Raptor,俄罗斯SHLV的RD-0164,液氧甲烷俨然成为时代潮流了

这篇去年Blue origin的访谈也印证了除BE-3外,其他的引擎项目也在平行推进,很可能就是这个液氧甲烷引擎,毕竟氢氧和液氧甲烷引擎有很多共通之处。

“We selected the BE-3 as our first orbital launch vehicle engine because it provides us with options to go with an all-hydrogen architecture if we choose to,” he says. “We have ideas. Some things are in development for other engines that we're developing, but we're not ready to discuss those today. Those would provide other options and other architectures.”

贝索斯至少砸5亿美金向这个公司。
Bezos Investment in Blue Origin Exceeds $500 Million
By Jeff Foust | Jul. 18, 2014

WASHINGTON — Amazon.com founder Jeff Bezos has invested at least half a billion dollars of his own money into Blue Origin, his spaceflight venture, a company official said July 17.

“We’re very fortunate to have a founder who has a vision and the funding and resources to match it,” Brett Alexander, director of business development and strategy at Blue Origin, said during a panel session of the Future Space 2014 conference in Washington. Bezos, best known as the founder and chief executive of Amazon.com, established Blue Origin in 2000.

Blue Origin has received a small amount of funding from NASA in the form of awards in the first two phases of the agency’s commercial crew program: $3.7 million in 2010 and $22 million in 2011.

“We got $25 million from the NASA commercial crew program, and that represents less than 5 percent of what our founder has put into the company,” Alexander said.

That would mean Bezos’ investment in Blue Origin is at least $500 million.

Blue Origin has been quietly working on suborbital and orbital launch systems, revealing few details about its plans outside of milestones in its Space Act Agreements with NASA. Alexander said Blue Origin’s architecture is based on the incremental development of reusable vehicles that take off and land vertically, but did not disclose details on specific designs or development schedules.

Bezos’ investment in Blue Origin represents only a small fraction of his wealth. Bezos ranked 12th in the most recent Forbes 400 listing of the world’s wealthiest people, with an estimated net worth of $27.2 billion, primarily in the form of shares of Amazon.com.

“As Jeff would say, he won the lottery and then is able to do what he really wanted to do, which is build a space company to get people into space,” Alexander said.

Blue Origin有这么大能耐么?5年内拿出一款大推力液氧甲烷机用于替换RD-180恐怕不现实。莫非是发展BE-3改版甲烷机,单机推力60吨级,并联个7台差不多。

250吨推力的BE-4,Bezos自投资金开发了3年,也就是说样机已经出来了,剩下的工作就是测试了。

按照Bezos在发布会上的说法,BE-4本来是给BO自己开发的RLV用的。我们之前都以为RLV是使用BE-3的全氢氧火箭,其实BE-3可能只是上面级引擎。
虽然未向公众公开,ULA和USAF一直都知道BE-4进展,这也是前太空司令部指挥官谢耳朵一直说碳氢引擎而非液氧煤油引擎的缘故,以致不少人以为SpX有个缩小版Raptor项目。

PS:改了一下,New Shepard是RLV的验证机,类似Grasshopper/Falcon 9R-dev和Falcon 9R的关系

那么上面级发动机会换么?

真够大牛的,居然还是富氧补燃循环,按理说甲烷机搞富燃补燃循环不是更省事。
250吨估计是真空推力,否则双发并联一级要加长太多。

如果你指的是RLV的上面级,BE-4的250t推力偏大了,BE-3的推力正合适,所以我想应该不会换。可复用一级配3-4台BE-4,一次性二级配1台BE-3,正好位于EELV的运力区间

不是改造Atlas V,而是取代Atlas V,我把它称之为Atlas V v1.1
http://www.spaceflightnow.com/ne ... rigin/#.VBo4QPmSyX0
According to Bruno, ULA is working on trade studies to design the company's next generation of launchers.

"We're four years away from our first flight, then we have to pass through a certification process that is appropriate to whatever degree of change that the vehicle has experienced," Bruno said. "So there are a number of years when the existing Atlas and Delta with the existing engines would be flying before the BE-4 is ready, then there would be an overlap where its feathered in to the future."

点评

呵呵,应该叫Atlas 6了。正好跟A6同步  发表于 2014-9-18 10:23

BO的技术来源还是个谜。
在Linkedin上找到了Stephen Hobart的简历,Hobart负责管理BO的所有项目(Director of Program Integration at Blue Origin) ,09年底离开PWR加入BO,曾参与MA-5, XRS-2200, RS-83/84和J-2X项目。但和Tom Meuller不同的是Hobart本身不是工程师出身,他擅长的是管理和整合。

ULA跳反,SLS的Advanced booster也搁置, 这么一来AerojetRocketdyne的AR-1多半没戏了

如果AR输掉替换RL-10的下一代上面级发动机,RS-25E再出个什么闪失(比如SLS被取消),10年后岂不是整个要死球了?

...Aerojet那部分还好,固体+常温+离子发动机稳的很,洛克达因这部分真的药丸啦

难道下一个十年美国液体发动机将是SpX和蓝源两足鼎立?仅仅一两年前,这是大家做梦也想不到的吧
