NASA tests hypersonic Blackswift, based on Nazi V-1 technology
Hello everyone.
I haven't seen anything about this mentioned anywhere except via a video (no text) on the Fox News website: video link
According to the (obviously out-of-date) information I've found, the Blackswift was rumored to be a super secret aircraft co-named HTV-3X that used a turbojet to reach supersonic and then a scamjet to reach hypersonic -- essentially a 21st century version of the J58.
Instead, the Blackswift described in the video uses pulse detonation engines, essentially a advanced version of the V-1 buzz bomb engine. This engine requires significantly less moving parts and achieves much higher efficiency than a turbofan, and is technically able to go hypersonic without any kind of "dual-stage" engine.
The Fox News video is total braindead... anyone have a good source of technical information on this? I'm under the impression that the aircraft was only unveiled, B-2-style, TODAY.
I've heard of the technology, just can't remember where. Personnally I think they inserted the word "Nazi" just to jack up ratings on an otherwise dry tech story.
yeah...cant see where the Nazis fit into this either, anyone have Der Dooks number, call and ask him..?
I used the Nazi descriptor to clarify which V-1 I was talking about.
The Fox News report may be incorrect, but every bit of information available on the Blackswift / HV3X, including the original (?) 2002 DARPA solicitation all the way though a March 2008 report from The Register and a June 2008 report from Wired, specfically state the Blackswift uses a hybrid turbojet/scamjet like the J58 with its turbojet/ramjet configuration.
The Fox News report is the only source I've seen that claims the Blackswift uses pulse detonation engines. The V-1 was the only aircraft I'm aware of that used pulse detonation propulsion until I found this.
I personally think this is really cool, because it could mean the Air Force has given up on hybrid scramjet engines for hypersonic flight and switched to a radically new technology. But no one seems to be explicitly saying this.

And to complete the circle, the no-brainer application would seem to be a new generation of hypersonic cruise missiles.

Well FOX news is an outstanding news organization that never publishes a story without throughly checking the facts so they must be right
