"DARPA, the renowned Pentagon crazyscience bureau whose nuttiness can only be properly expressed in terms of a conceptual Tardis-style hyperdimensional fruitcake"

I've been enjoying the exaggerated descriptions of DARPA but I think you may be reaching the very peak of available hyperbole here! Where does we go now? You may need to read some E.E. 'Doc' Smith - a true master of excess!

This brings in several El Reg correspondence themes:

What is the carbon footprint of anyone using this thing? I'm pressured to turn off my computer monitor when I leave my desk at lunchtime.

Will this help in the War on Tourists? Would it have prevented 9/11, 7/7 or any other number?

Will it stop nasty American border-controllers from looking at my alien hard drive?

If I think about it I'm sure I can bring in DNA testing of schoolkids, Paris Hilton, ID and (a new theme) the Credit Crunch.

amazin'

"DARPA*, the renowned Pentagon crazyscience bureau whose nuttiness can only be properly expressed in terms of a conceptual Tardis-style hyperdimensional fruitcake, able to hold many times more nuts than can fit within its apparent measurements"

Are you sure your reffering to DARPA and not some new breakfast ceral.

Mine's the one with the pockets that don't work until high speed

"Would it have prevented 9/11, 7/7 or any other number?"

With a bit of luck it will stop them 118 guys running around the streets

I am sitting in my hypersonic bomber, and ground troops call in an airstrike. I fly over and suddenly notice that the bombs are attached to the top of my aircraft. Its a good thing my aircraft can do a barrel roll or I would never be able to by those allies^W journalists^W people.

I am sitting in my supersonic fighter and a boat load of Somali pirates are rowing towards towards my carrier. They suddenly appear on my radar as they leap into the sky. A launch a missile and illuminate the pirates with my radar so the missile can stay on course. Its a good thing my fighter can do a barrel roll because my radar won't point upwards and those pirates are gyrating all over the sky.

I am in my space plane on my way to moon base alpha when all of a sudden there is a massive nuclear explosion at the base. There is a big heat shield on the belly of the plane. Luckily I can do a barrel roll and duck and cover behind that.

Seriously, is there a reason for a modern aircraft to be able to do a barrel roll?

god thats hilarious ....

>is there a reason for a modern aircraft to be able to do a barrel roll?

So we can watch films like this one http://www.youtube.com/watch?v=WJ546BEps

Obviously

As in, pork barrel?

More seriously, I believe the aforementioned manoeuvre is there as a test of flight control, demonstrating that the craft, an addition to being faster than a very fast thing indeed, can also be controlled in flight.

Hopefully the in-flight breakfast will consist of scrambled-eggs, and not the inedible fare offered by American Airlines?

From my RAF Days I remember an SR-71 trying to land in the UK didn't slow down in tome and had to make a U turn to get to Mildenhall.

It took most of Europe as it was still doing Mach 3 at the time

If an Aircraft can Barrel Roll it has the capability to launch Nuclear Weapons as they are released as the aircraft launches as it rolls through Vertical as it turns away (Runs away from the blast).

Conventional warheads are released while the aircraft is level.

= Mine is the one with the Tactical Air Launch manual in the pocket

Because after reading: "DARPA*, the renowned Pentagon crazyscience bureau whose nuttiness can only be properly expressed in terms of a conceptual Tardis-style hyperdimensional fruitcake, able to hold many times more nuts than can fit within its apparent measurements." My keyboard and monitor are rather damp with coffee. I think you may have hit critical mass when it comes to describing DARPA but I look forward to future descriptions.

Oh and Arch Lineberger, here is a dollar go buy a sense of humor and lighten up for fucks sake.

Invective is the word for it ! Funny is though.

Paris, whom I have renamed Spanner as she tightens my nuts.

a silly question perhaps but can these ramjets go fast enough to escape gravity allowing for the space between enough air to ramjet and real space ?

what is the distance you need to cover to do it and if not as i suspect how much conventional rocket fuil would be needed to boost such a craft from these ramjet speeds to get to gio stationary orbit.

i guess the hypothetical question is, can this new ramjet help to make cheaper space flights in combination with other tech such as the virgin one uses to go up and come back down safely perhaps!

erm... an aircraft performing a barrel roll will not "roll through vertical"

did you mean a loop? (half loop if lofting nukes)

or is it some complicated perform-half-twist-while-doing-half-loop jobby?

paris because we both need edumacating.

i edumacted myself using wicultpedia and what i thought was a barrel roll is in fact an aileron roll.

Also, i think i just made my eyes bleed by using "edumacted" and "wicultpedia" in the same sentence.

my bad.:S

Accepted

lol

Let's not forget that they invented(or at least envisioned) cloud computing back in the late fifties/early sixties(look up Multics sometime). While they do have more misses then hits, some of those hits were at the edge of the net. So your "hyperdimensional fruitcake" is a necessity to how we live(though the term would probably be misinterpreted here).

The main reason why Liquid Hydrogen fuel was mooted for hypersonic aircraft, was it was used to combat kinetic heating, as the Cryogenic fuel was heated by the airframe, thus dissipating heat & converting it back into it's gaseous state, before reaching the scramjet for combustion...

JP-7 was the fuel used on the SR-71 Blackbird, & was specially refined to have a high flash point, for the Blackbird's J58 "Turbo-ramjet" engines to use...
