NASA Tests Hypersonic Blackswift 487

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.

    It's not that THEY'RE dumb (which they are so very dumb) but rather they feel the need to dumb down everything for their audience.

    I want to punch that Fox man in the face. And I feel so bad for Ken Christiansen (sp?). It seemed apparent he was not prepared to deal with such a moron.

    I'm somewhat confused as to what has been "unveiled".
    Everything I've read so far says that this plane is still in the "sketches and mock-ups" [wired.com] stage.

    Though I guess someone found the time to do a slick render.
    Maybe the PR push is an attempt to keep Congress from cutting their funding.

    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.

    The alarming thing is not that Fox News readers do not reflect upon the standard of intelligence at Fox News Studios, rather, it reflects upon the intelligence of the American Public in general. After all, this is a free market, and Fox News is only delivering the quality that people are demanding in that free market.

    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!

    I don't think liberals would care if

    1) They knew that it was an intentional troll
    2) They were sure no-one (outside of a mental institution) was watching it and actually taking it seriously.

    The problem with such trolling on such an epic scale is that America is a democracy (and has a democratic mindset) - so that people who believe trolls actually affect us at the polls, and in every other facet of public life that's based on democratic principles (from flooding various companies with angry calls, to NOT getting outraged when someone in a position of power abuses it - whatever that may be). This also applies to the "liberal media", but for whatever reason, Fox News seems to be by far the worst offender of fabricating bias, inappropriately inserting emotives, and misquoting science/facts to suit their own bias (maybe because there are more science factions/studies biased to liberal viewpoints, maybe because reality itself is liberal, who knows?).

    Apart from anything, if people did believe even only half of what they saw, it's terrifying to think how much power the newsmedia holds. It's amazing to think that it's potentially several orders of magnitude more destructive than even the most dangerous illegal weapon someone could obtain - sure a bomb may kill a buildings' worth of people, but can it change an election?

    The fact is that liberals have control of the networks - I saw poll that showed essentially all journalists at CNN, ABC, CBS etc vote for the Democrats.

    Uh, no it was that around 90% of journalists that make campaign contributions contribute to the Democrats. But the number of journalists making campaign contributions was around 10%. So you can only say for certain that <10% of those journalists support Democrats. The party orientation of those who donate doesn't necessarily match those who don't. I could conceive of a scenario where those who don't donate are greedy and figure they're sufficiently supporting the Republican party through biased news worth far in excess of the monetary contribution of their Democratic-donating counterparts. Not saying that's the case, just that the data that's available could be consistent with either scenario.

    Now, most contemporary journalists are also pretty scientifically illiterate, which make them an easy target of ridicule in the technical community. And their understanding of economics and far too much else is often not much better. However, that Fox talking head in the linked video seems like a particularly egregious example. Fox News appears bad to anybody who isn't blind since they seem to insist on giving equal or more time to the emperor and his tailors than to the small child and his observations.

    Nevertheless, you might also want to consider that many journalists get to see and hear about the raw information before it gets massaged by editorial boards that are selected by corporatist management. So when it comes to coming to conclusions that only require facts and common sense, not technical knowledge, like the general state of the country and how various political parties influence it, they're likely to be better informed than you.

    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.'

    the really interesting bit is that *NEITHER* the democrats or the republicans are very far from what the rest of the world would consider 'ultra right wing' or 'conservative'. The fact that even here on ./ people with an probably above average intelligence have swallowed that left/right bullshit hook line and sinker.

    In any other country there would be a real left wing and something close to your democrats or republicans as right wing or ultra right wing.

    This assumes that the political/social interests and standards in the US match those of the rest of the world, which they most certainly do not. You do make a valid point though that the Democratic and Republicans parties are not nearly as different in practice as they would like us all to believe.

    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.

    They hire people who make them money. They are big business corporations, after all.

    I would believe that if the "liberal" run networks had more viewers. But that's not the case. In cable news, Fox gets more viewers than all the other cable news networks combined. So, if their job were to get more viewers (and thus more money), then they would have followed Fox's example years ago.

    "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.
