always seems like the coolest concepts are the most likely to end up DOA.

Probably not the actual aircraft, there's a few aircraft that are black at the moment but dont look much like their concept drawings.

This new shape in the video look like a mix between the HYPERSONIC FLIHGHT RESEARCH VEHICLE of Lockheed and theire old concept of the Blackswift . It look realy cool and the intake seem very different of the SR-72.

Possibly related to what we were talking about earlier in the thread?.....

I suspect AETD is more than ADVENT. Officially ADVENT is farther along, but I have heard from multiple sources that there is something that completely changes things.

The three Stream in the AETD engine ??? is it possible a new engine like the J-58 ?editby]edit on 27-2-2014 by darksidius because: (no reason

The third stream will do wonders for fighter type engines. An F135 with pressure ratios approaching a high bypass turbofan will be amazing as far as power and efficiency go. It still has the issue that all turbofans have though, slowing supersonic air before it hits the compressors.

Ok I understand, and with a third Stream engine what maximum mach is possible ? 2.5 mach or near mach 3 ? is it different than the Advent engine ?

Is that still an issue? I thought we'd dealt with that already, in a very efficient fashion. (whistles, looks up)

If one had to postulate the theoretical top speed of these new engines what do you think they could be?

Faster than Mach 1.
What's kind of interesting too is how slow it can go.

Is it the new propulsion system we speak in this thread " the leap ? "
"" Larry Spencer said the new engine differs from today’s engines, which pull air in through fan blades. “This new technology actually pulls air inside the core and gives us a lot more power and makes it more cost effective” in range, fuel, and maintainability, he said at the conference." Its a little like a ramjet no ???

It may use aspects of AETD/ADVENT but the actual technology is about as black as you will (not) see.

I don't know for certain, but I'd put money on it.
Thats not due out to the mid 2020's that too long to wait

No, it won't be OPERATIONAL until the 2020s. It'll be flying within a year to start testing.
