    More seriously, it is probably a condition imposed by the Baghdad government.

    Don’t think they’re in a position to be setting conditions for help.

    Exactly. really weird. Asked why to AdA, no answer yet…

    The last thing you need is one asshat from ISIS who’s learned to fly shooting at a coalition plane with no missiles.

    Kilt, blue paint & claymore. What else do you need?

    Add yellow paint and that’s roughly what Poroshenko said.

    Massively limiting higher education options? Edimburgh etc universities are massively limited now?

    Yes, they are. There’s a lot of Scottish students who want access to Universities across the union. One such student even asked the question wrt having to pay £35,000/annum foreign tuition fees in the UK and she wasn’t answered. Every university has niche areas that it does better and sometimes students just like the area, or the space from their parents.

    Furthermore, 3 of the world’s top 10 universities are in England and 6 of the top 40. By comparison Edinburgh is the only Scottish university in the top 100:

    The adaptive cycle engine is building on decades of military and civilian jet engine research. Innovative architecture shifts air flow between the core, the main bypass, and a third stream to achieve thrust, optimal performance, and fuel efficiency.

    It actually appears to have 4 streams in total, the main bypass seems to have 2 streams.

    it look too complicated to fit into any air to air missiles or even SAM , an aircraft may be

    Yes. I guess I’m back on the thread title subject.

    oh actually i was comment about the ability of aim-120 to shot down fast aircraft and bomber at high altitude ( ex : XB-70 )
    btw can the SM-3 , THAAD , PAC-3 shot down aircraft or they are only useful again ballistic missiles ?

    PAC-3 can. SM-3 and THAAD are BMD only. SM-3 is for exo-atmospheric intercepts only and THAAD is high altitude endo-atmospheric and exo-atmospheric, 20-150km altitude I think. This quite a nice little diagram to show everything:

    It is worth remembering that the missile performance being cited in the Breaking Defence article is the work of academics who perhaps have no experience of real-world missile engineering. So their SM3 performance figures could be over-optimistic.

    Several years ago Professor Postol of MIT modelled the performance of the two and three-stage Ground-Based Interceptor, and claimed that his results ‘proved’ that the US MDA was deliberately releasing false information that did not reflect the true performance. The possibility that his own modelling was inaccurate was not mentioned.

    Can’t comment I have no clue as to range.

    What is a point of contention is whether the latest tiff with Russia will help lobbyists uncancel Block IIB.

    Given the ‘no’ campaign’s focus on business implications, currencies, and other such dreary affairs, I find the following from Edmund Burke rather appropriate:

    But the age of chivalry is over. That of sophisters, economists, and calculators has succeeded; and the glory of Europe is extinguished for ever.

    The modern disease of economics may have affected England to a greater extent than any other nation, but truly it is the great affliction of our age. If a question such as national independence can be seen to hinge on a balance sheet, then truly there is no longer any nation there worthy of the name — merely the fossilised remains of what once was.

    Only if you can’t actually use a calculator.

    You’ll note on page 14 he claims that only £590m of current UK budget is spent fully subsidising Scottish students in higher education:

    http://worldofstuart.excellentcontent.com/WeeBlueBookDesktopEdition.pdf

    Yet it doesn’t add up, there are over 2.3 million students in the UK of which nearly 10% are Scottish:

    https://www.hesa.ac.uk/

    Tuition fees paid by non-Scottish UK students are around £11,000/annum. It doesn’t take a genius to figure out that £11,000 x 200,000 is a lot more than £590m. Furthermore post independence higher education will only be free for Scottish students at Scottish universities, they will no longer be free to choose from any UK university, massively limiting higher education options.

    is the poster boy of Scottish independence = Mel Gibson as a symbol from the movie Braveheart

    Yes.

    I think it is simple. NATO has an interested that the airspace is policed, well Scotland could allow them to do so. There is no need for Scottish armed forces. The money can be better spent on other projects and not on some elitist flying club.

    This sounds more and more like devolution max and not independence all the time. Basically they want the UK armed forces still in their country without paying anything for it. That’s just irresponsible.

    There are other solutions for Mach 4-6 flight with even higher Specific Impulse:

    cant you explain a bit clearer , i dont quite catch what you trying to say ? ,

    Liquid ramjets offers higher specific impulse but liquid takes up more space per lb, so although solid fuel offers lower specific impulse, you can fit more lbs of it inside any given rocket body.

    VFDR cannot be flame out like ramjet , at lower speed scramjet and ramjet can get flame out ( that why they need a rocket booster ) , also Ramjet often have better range and speed than VFDR cause it dont have to carry the oxygen

    Okay, I understand why the speed can be lower, but what restricts it at the top end?
