As I understand it Reaction Engines' business plan isn't that they need Skylon to be developed and successful to generate any ROI.  Instead they're looking to be a heat exchanger technology company and so could be starting to make a return quite soon.

True the company has already been going for many years, but it's a small company and has been generating some income. So I'd guess that the private investment so far is a lot less than Elon Musk has put into SpaceX. Probably more like the amount John Carmack has invested in Armadillo?

Another new video http://www.reactionengines.co.uk/troy_movieqt.html is in REL's May monthly update (http://www.reactionengines.co.uk/news_may10.html).

This is a concept animation of their proposed Troy Mars mission, which of course uses Skylon to get the necessary components to LEO. Further details on Troy are in the paper at http://www.reactionengines.co.uk/downloads/mars_troy.pdf.

Nice, Adrian Mann's work is excellent.

As much as I love Skylon and anything like it, I can see wormhole/Compression Space Transport technology arriving before any hardware gets built  ;D

I know what you mean ;)

As I see it, a big issue for obtaining funds to even attempt to build Skylon is lack of a roadmap from proving basic technologies (such as current heat exchanger work) to the billions needed for a full vehicle. Maybe Reaction Engines have such a plan and it's too commercially sensitive to discuss. But like you I can't see it happening without some smaller - and useful - intermediate development steps.

P.S. That's pre-supposing it's all technically achievable, which isn't a universally held view ...

Japan "baraban pre-cooler" followed recently in India with Russian assistance. Sabre is deeply cooled rocket not a scram or a ram converts to all rocket around mach5-6 then pitch up to orbit. And fact is Japan and India are way ahead of Reaction deep cooled technology.

This sounds WAY too familar... I'm thinking I've heard of this before in relation to the RASCAL program. I seem to recall a report showing a "deep-cooled turbo-rocket" called the "KIL-N" cycle I think?? Basiclly it used an RL-10 engine fed by LH2 and Liquid Air drawn from a set of compressor intakes and heat-exchangers...

I'll see what I can find again.

I would let to get the learned opinions of the members about this proposal:

My opinion: the editor who came up with the title is a MORON.

"spaceplane that will take tourists into orbit at five times the speed of sound"

Gah.

"The Skylon’s innovative engine uses propulsion to reach the edge of the Earth’s atmosphere..."

Astounding! It uses propulsion!

And so the endless circle of life comes to an end, meaningless and grim. Why did they live, and why did they die? No reason. Two hundred million years of evolution snuffed out, for in the end Nature is horrific and teaches us nothing

The Daily Mail article listed above is a rehash of http://www.theengineer.co.uk/in-depth/analysis/out-of-this-world/1004713.article.

Reaction Engines also recently made a submission to a parliamentary select committee on the new UK Space Agency (see http://www.publications.parliament.uk/pa/cm201011/cmselect/cmsctech/memo/space/m09.htm).

The submission contains the following interesting titbit:

Quote
Since the [UK Space] Agency was formed the main interaction with Reaction Engines has related to the organising of a major international review of the SKYLON spaceplane to be held on 20th to 21st September. This review will host over 100 experts from around the world to assess the economic and technical aspects of the SKYLON concept. The outcome of this Review, supported by an evaluation from the European Space Agency will give the UK Government confidence that, should further support to project be given, it will be on the basis of a thorough assessment.

Reaction Engines' September newsletter includes the following about the recent review:

Quote from: http://www.reactionengines.co.uk/news_sept10.html
On 20th and 21st September, the UK Space Agency held a System Requirements Review on the commercial and technical capabilities of SKYLON at the International Space Innovation Centre at Harwell, England. Approximately ninety invited experts attended the event venturing from various European and global nations including the USA, Russia, India, Japan and South Korea. In the months leading up to the Review, three engineers from the European Space Agency (ESA)  were seconded to REL in order to investigate our technology, methods and analysis. ESA will provide the UK Space Agency with an official report on the Workshop within in the next month.

The preliminary results of the event are indicative that the majority of the attendees consider SKYLON to be a viable concept. Responses to questions on the project provided a clear and honest overview of the programme. Dr Constantinos Stavrinidis, Head of Mechanical Engineering at ESA, gave the closing address and commended the competence of REL and its SKYLON concept.

REL hopes that the feasibility of the SKYLON programme is no longer in doubt and that the commercial and technical aspects of the project are well understood and recognised. Over the coming months, discussions with government, industry and private investment are due to take place and REL looks forward to further progressing SKYLON.

The UK Space Agency’s press release for the event is available at http://www.ukspaceagency.bis.gov.uk/19661.aspx?pf=1

Recently, one of the recurring questions has been the degree of government involvement in the SKYLON development. To date, the public contribution stands at 15% with the remaining 85% provided by private investment. REL intends SKYLON to remain as commercial a programme as possible.

I had a looong talk with the Reaction Engines representatives, a very usefull one, so when I will have some free time to spare, I will write some extract of it.
