NASA Tests Hypersonic Blackswift
dijkstra writes "Blackswift was previously rumored to be a super secret hypersonic scramjet-based aircraft co-named HTV-3X, essentially a 21st century version of the SR-71. Today NASA has unveiled the real Blackswift (video link), which uses pulse detonation engines (PDEs). A PDE is essentially a modern version of the old V-1 buzz bomb engine. This engine requires significantly fewer moving parts and achieves much higher efficiency than a turbofan, and is technically able to go hypersonic without any kind of 'dual-stage' engine."
Please warn us when linking to Fox News. Jesus those people are dumb.
How we know is more important than what we know.
I'd prefer to stay stupid. Thanks.
Just because Fox interviews a NASA analyst doesn't mean NASA developed the thing. The video clearly says it's the air force that's developing this.
Holy shit that was a pain to watch. Billy is a fucking retard.
"Can you explain in english not in science-talk."
Oh, you mean english to people who aren't slack-jawed idiots. The way he says it makes it sound like he's proud that he's so fucking stupid.
What a fucking jackass. How can someone that stupid be put out there as a news-person? On national television?
I'm hoping for the one day when the scientist being interviewed tells the guy to get a fucking education and then explains what's going on in adequate detail with plenty of scientific concepts.
Sorry, but 'fewer' moving parts? :)
Jesus built this hot rod.
It's no secret, nor is it new...

It's also been on the Military Channel, and Discovery...
The AIR FORCE is conStructing this HYPER sonic jet exploder thingy, with the help of JESUS, in order to fly at 10 times the speed of sound over countries where POOR people who HATE us live, in order to deliver with very high efficiency SWEETS and other confections which they need to live. They'll drop right out of the bom...CANDY bar bay. The Pentagon calls this the SNICKER candy bomb. At least they were snickering when they told the story to Fox News. Praise the lord

I don't think any of the links you provided mentioned the use of a pulse detonation engine, only dual-mode scramjets for hypersonic flight and turbofans/jets for takeoff and landing.
--RIAmAses! Let my MP3ople go!
Could this be the Aurora, the "triangular shaped" airplane with the "donuts on a rope" contrail that various people have reported seeing over the years? (I saw something on discovery channel about it)
now, don't get me wrong. this is a cool bird. but I wouldn't say it was cooler than the SR-71.
I've found a few better articles and videos, here, here , here & here.
It's probably designed to be the replacement for the "blackstar" program, which doesn't exist, but is hands-down the very coolest thing out there, the only thing cooler would be a functioning Orion spacecraft.
But this looks like it might have the capability of taking the place of the blackstar "mothership", although I bet with less performance & payload; as this isn't designed to be a Mach 3+ cruise nuclear bomber, that's understandable. but those cold-war birds have got to be tired by now, and looking forward to retirement. i think one would look great in my driveway as a static display.
I do wonder what they are going to use to replace the orbital component, which was probably based on the X-20. Maybe a NASP? The X-43?
Why, yes, I AM a Pagan Libertarian.
"This engine requires significantly less moving parts"
Fewer is for quantities you can count. Less is for quantities you can't count. So unless you're implying that NASA scientists took a V1 Buzz Bomb engine (whatever that is) and poured out a heterogeneous liquid stream of moving parts until only puddles remained inside, it's FEWER moving parts!
The V1 flying bomb used a pulse jet engine rather than a pulse detonation engine - the difference being that a PDE burns at a supersonic rate whereas a regular PJ wouldn't be able to get to those speeds.
Pulse jets are surprisingly easy to build, and I'm going to flagrantly link to my own build log of my engine being built with videos of it running/imploding here.
Videos are all here.
Cheers.

The difference is that they're very very different kinds of engines really. Sorta like the difference between a turbofan and a piston engine in an aircraft. Both suck in fuel and use a propeller to push the air towards the back, but they're very different engines anyway.
A scramjet is, sorta, an afterburner without the turbojet in front of it. Think just a de Laval nozzle, sorta, where the airplane's own speed shoves the air from the front, and you inject the fuel and light it in the back. It can only operate at hypersonic speeds, because it does need the air coming in really hard and fast, and it burns fuel continuously. There is no need for pulses or detonations.
A pulsejet, well, think a pipe with a valve in front. Sorta like this, with "front" being downwards:
The T is the valve.
Air comes in, you inject the fuel, and ignite it. The pressure closes the valve, so the only way the burnt gasses can go is backwards, pushing your aircraft forward. Then the pressure equalises, the valve opens again, and the cycle starts all over again.
This one can _only_ operate in pulses. On the up side, it can operate at subsonic speeds too. It's also a very simple and robust engine. The V1's pulsejet could be riddled with holes and still generate most of the thrust. The RAF found it easier to just tip it over, with the tip of the fighter's wing pushing the V1's wing upwards, than shoot them.
Downside, also generates massive vibrations. The buzz of the V1s could be heard from the ground. It's a bit like flying a jackhammer. Which is one reason it never got too popular for manned aircraft, or aircraft which were supposed to fly more than once.
Well, that's the simple explanation anyway. There are more modern designs which, for example, do away with the valve and essentially just choke the flow via a nozzle to achieve the same effect. But that's the general gist of it.
A polar bear is a cartesian bear after a coordinate transform.
VxD Source news is hugely better than Fox, I agree with you.
I thought the idea was to put them against the wall and then shoot them. But sealing them inside a wall and then flying a plane against it might work too. However I don't think they will be doing much apoligizing afterwarts.
In conclusion: I like your plan, but I suggest letting them apoligize first.

Surely the correct response would have been 'no, that was an artist's impression.'
The news anchor may be employed to use baby-talk, but there's no excuse for a supposedly informed correspondent to go along with the idiocy. The pride in ignorance is obviously annoying him, why doesn't he challenge it?
Equally when asked to explain in 'English, not science-talk,' perhaps he should have said 'Yes, perfectly possible. Let me explain' and delved into some of the simpler theory of reciprocating engines, turbojets, high and low bypass fans and scramjets. When challenged he could then say, "what with words less than 3rd grade level? Ah, no sorry, not possible.'

Yeah, I'd heard American news was bad, but I didn't realise just how bad.
"How can a human cope with going that fast?"
What is this, 1850? The scientist didn't explain very well that you only feel any force under acceleration admittedly, maybe he thought that when the guy said 'going fast' he meant 'accelerating fast'. But OMFG, some people obviously just don't think... don't notice that travelling at 500mph on a plane feels no different to being at a 'standstill' (ignoring the earth/galaxy's rotation), it's only the acceleration that stresses the body. Later on he was saying "Surely they need some kind of special equipment?" :/ sure, they need a hypersonic plane..

Everything that Rupert Murdoch does is avowedly anti-intellectual. Over there it's FOX News and the New York Post; over here it's the Sun, the News of the World, and the current Labour government.

I really do wonder what they're dicking around with out there. The two bits of evidence I heard of supporting the idea of a fancy post-SR-71 wonderplane were the donuts-on-a-rope contrails (which the link says can be produced by conventional aircraft under the right conditions) and linear earthquakes picked up on seismographs that do not follow any existing fault line that seemingly originate in the atmosphere. I've seen that "fact" mentioned before but have no idea how accurate it is.

I have no proof one way or the other, I just think it would be surprising for the government to retire something as valuable as the Blackbird without having an even better replacement in the works. Then again, using logic to explain government decisions is often a losing proposition.

At least this propulsion system has been flying since at least 2005 (I don't remember the season). It sort of sounds like a piston engine, but leaves a contrail of "puffs" and appears to be very fast.
I heard what I thought was a strange-sounding small plane. Found the contrail, and the head growing far ahead of where the sound was coming from, and I couldn't see the contrail source. Maybe 20 seconds from hearing the sound from the north to seeing the head of the contrail disappear to the south. It was flying down the Front Range of the Rockies. I was just north of Gunbarrel, Colorado.
I googled around and found conspiracy nut sites talking about "Aurora", which fit my observations well. Since then, I've just been waiting for it to finally be revealed. I guess the research has gone on far enough to start production.
Please do not equate American News with Fox News. Our news may be lacking, but Fox News is that media cousin that's always getting wasted at family picnics and no one likes.

Well, it's Fox News - that cub reporter was oh so promising in his better days at another network. But now... Thank Rupert Murdock for yet another sterling contribution to public science...
He reminds me of Carrey so much that I expect his face to stretch like in 'The Mask', or 'Bruce Almighty' hijinks to break out on the set at any moment.
Tiller's Rule: Never use a word in written form that you've only heard and never read. You will end up looking foolish.
It isn't just that they act dumb. It might be just me, but those Fox newsreaders give me the creeps. It's their eyes. Their body language and facial expression are so animated, but their eyes are so lifeless.
I may be politically biased against the network, but there is something in the flawless but soulless choreography of Fox news that stinks of evil. The effect reminds me of C.S. Lewis' novel That Hideous Strength, in which a government think tank called NICE manipulates its members using their ambitions and insecurities. As their ambition drives them toward the coveted membership in the inner circle, their fear drives them further into themselves. By the time they make it into the inner circle, there's nothing outwardly left of their humanity to enjoy it. They can pass superficial inspection, but the closer you look, the more obviously robotic they are.
What makes That Hideous Strength such an effective story of the supernatural is that the mechanisms of damnation are so psychologically plausible. Anybody with sufficient money could actually put the NICE methods for turning people into passive tools to the test.
I don't know about the people on the screen, but Fox definitely plays this game with its viewers. It appeals to greed and fear.

Religion is easy. It is obsurd to think that the car came into existance through millions of random design mutations that somehow did not cause it to blow up. The only reasonable explanation for the existance of the car is that it was designed and created by some intelligent being. Therefore God exists. QED.

Only example I know of something flying with PDE is Long-EZ and the technology still has a ways to go.
In fairness, humans DO have a problem with high speeds, but it's biological, not physical. A person's reaction time has a lower limit, and it is quite possible to exceed that limit and cause problems with a person's control of a vehicle regardless of gee forces. If this were not the case, then all it would take to be a race car driver would be an extra capacity bladder.
That being said, I'm pretty sure the anchor meant "wouldn't they be crushed?" Given that the main viewers of morning news programs are soccer moms killing time after their spawn have gone off to what passes for education in this country, I'm sure tat was their interpretation as well. After all, minivans are DANGEROUS when you go fast - that's why you have car seats and a cell phone. For emergencies.

Oh, come on. All of our news sucks - clearly Fox sucks much more than all the rest, but the rest is horrible too. All the other new organizations seem to actually be pursuing Fox News, becoming increasingly crappy in order to become increasingly profitable.

"I don't think it's reaction times that matter so much as perhaps just brazen balls out fearlessness. Fast reaction times are useful when you overstep the limit or someone ahead blows a tyre out or something like that, but most of the time I don't think it's the defining factor in what makes a good race-driver. For most types of racing I'm of the opinion that anyone could do it with a bit of tuition and cash."
Perhaps - but "overstepping the limits" or "someone ahead blows a tire out" happens ALL THE TIME in racing; while anyone may be able to turn competitive times on a racecourse, that's different than an actual race. Joe Blow may last one or 2 races, but without getting his reaction times up to speed he will either lose miserably or crash - either way his racing career is likely to be quite short.
It's like saying because Ray Charles could be a perfectly good driver, because he drove a Mercedes out in the middle of the Mojave; sure, he operated the controls competently, but lets not call him a "driver".
Likewise, comparing lap times for professional racers in a "reasonably priced car" to the average guy is ridiculous; drop them both in an F1 car and see what happens - I mean, the only difference is that one is faster than the other, right?
Let's make it even simpler - American style drag racing. Simplest automotive sport in the world - go 1/4 mile as fast as possible. No turns; pure acceleration. Now, lets put Tony Schumacher in a Honda Accord next to me in my identical car and race. We will probably get to the finish line within .400 seconds of each other - .400 being the difference between when he reacts to the starting light and when I do. We will both finish in about 15 seconds with a top speed around 90 miles per hour. AWESOME - that means I'm competitive with a 5 time National Champion - racing just can't be that hard.
Now, put us in his car - a top fuel dragster. A competitive car will travel the 1/4 mile in under 5 seconds, and finish at well over 320 miles per hour. Are you really going to say that I will still be competitive in that car? Assuming I actually survive the trip?
That's the problem with egalitarianism - some people really ARE better than others.
