NASA Wants To Get Supersonic With New Passenger Jet (networkworld.com) 144

coondoggie writes: NASA wants to put a supersonic passenger jet back in the sky that promises to a soft thump or supersonic heartbeat as the agency called it - rather than the disruptive boom currently associated with such high-speed flight. The 'low-boom' aircraft known as Quiet Supersonic Technology (QueSST) will be built by a team led by Lockheed Martin Aeronautics. It will cost $20 million to develop baseline aircraft requirements and a preliminary aircraft design.

  • More pork for Lockheed Martin.

      More pork for Lockheed Martin.

      Obvious pork is most definitely obvious. After spending $20 million, NASA gets... a pile of paper. For $20 million, not one sheet of metal will be bent, not one rivet will be hammered, not one seam will be welded. And why is NASA spending this $20 million? Because it might not work. Or maybe nobody will want one.

      After 70 years of this bullshit, we're suffering far more than we realize. Because of contracts like this, big business is now convinced of its own infallibility, and Republicans are convinced of the ineptitude of government. This is not the capitalism they've been selling us all these decades. This is ridiculously socialized risk. If we were pursuing actual capitalism, Lockheed would have done a market analysis, possibly discovered that there's a profitable niche going unfilled, and attempted to fill it by designing and building an aircraft. With their own goddamn money.

      Instead, Lockheed did a market analysis, possibly discovered there's a profitable niche, and hedged their bets by shoving their risk up our collective asses. So now it's all upside for Lockheed. They can't lose. If it turns out that designing planes on paper is still a stupid idea (F-35, we're looking at you), and the pile of paper NASA receives can't be used to build a plane anybody wants, it's "government" that failed. "NASA Failure!" "NASA Boondoggle!" "NASA's Plane Can't Fly!" The headlines write themselves.

      And so the perception that government is incompetent is reinforced, and Lockheed Martin's stock doesn't take a hit, because hey, they delivered a pile of paper. That's what the contract specified. US businesses are never wrong, US businesses never make mistakes, especially not big expensive multi-million dollar mistakes. No, only governments do that.

      It's insidious. It's wrong. Every contract like it should be opposed by every American.

        F-35 is really the Space Shuttle replay on steroids. The Navy want a Harrier, the Army want a Warthog and the Air Force want something fast. Just like the Space Shuttle filling the role of two different launch vehicles and needing to be strapped onto the side of another rocket (it must have required the work of multiple geniuses to fly at all) we have a thing meant to be a lot of other things, mostly so one company can own a market.
        So it's got nothing to do with "designing planes on paper" - that's what e

            Last I looked the Marines were in the Navy and also the Army were asked what they wanted which added more compromise to the design.
            Perhaps you should think before jumping on posts to nitpick over trivia and getting it wrong? An addition of information is useful, irrelevant distracting noise just looks like playing some pointless mass debate game.
            • Uh, the Marine Corp are *not* part of the US Navy, no sir-ee - they both fall under the Department of the Navy, but they are both entirely separate forces with their own separate commanders and their own separate budgets.

              And no, the Army had utterly no say at all in the F-35 design - they provide no budgetary support to the program either.

              How about you actually do some research on the topics before you try to argue your points, it stops you looking stupid.

              • by dbIII ( 701233 )
                As stupid as irrelevant nitpicking over an analogy? The topic is waaaay back over there Mr "run by the Navy but not part of the Navy". If you let go of the analogy and start running now you may catch up with the topic.
              • I should add - not only arguing about an analogy but about one I've shown is irrelevant.
                The F-35 has problems due to excessive compromise which is nowhere near the issue here with the supersonic transport design.

    • It's a stepping stone. The long-term hope is for hypersonic transports which reduce the energy cost by "flying" above the atmosphere (sub-orbital ballistic trajectory) for a good portion of the trip. But to do that, you have to go through the supersonic regime.

      JAXA is already doing test flights of its low noise supersonic aircraft. It looks like the technology has reached the stage where a new supersonic passenger aircraft could be viable, and Japan wants to be at the forefront of that technology. The US seems to have realized the same thing and got its aeronautical R&D body, NASA, to look into it. $20m for what could be a new market, one which Airbus will be late to, seems like a good deal.

    ...and what sort of fuel economy will it get?

    Boeing failed with the SST, due to anticipated fuel costs not meeting market needs. Similarly with the Concorde, which couldn't operate profitably.

    Sure, there are some rich folk who would pay for short flight times, but the mass market is price conscious. The problem with supersonic flight is not sonic booms, but efficiency.

    Finally, why is NASA wasting taxpayer money designing passenger aircraft for the civilian market?
    • by Anonymous Coward

      Concorde operated profitably for quite some time. The problem was, and still is, that only a few routes make commercial sense. So the SST a low-volume product, which combined with stupid high R&D costs (government footed the bill for Concorde) makes them a very risky proposition for the aircraft companies to develop, and for airlines to buy.

      Now, long haul, business heavy routes benefit the most, and if they do manage to make it quiet enough, a US transcontinental route starts to look really interesting.

        So by "operated profitably," you mean it didn't operate profitably, it just pushed development costs onto European taxpayers.

        Concorde operated profitably for quite some time.

        No. This is wrong. The Concorde never even came close to being profitable. It received $8000 per passenger-trip in subsidies from British and French taxpayers. But as the costs continued to climb, even that wasn't enough, and the politicians decided that there was actually a limit on how much they were willing to tax poor and middle class people in order to subsidize filthy rich Concorde passengers.

        • For those who don't grok just how atrocious Concorde's fuel economy was, just look at the right-most column of these charts [wikipedia.org] (liters per 100 km per seat). Concorde was 16.7 L/100 km per seat.

            The oldest aircraft in that list first flew in 1981, Concorde first flew in 1969... Aircraft are becoming more efficient over time, but development of supersonic passenger aircraft basically stopped in the early 70s.

          I would love for you to back that up - after privatisation, British Airways increased the ticket price, still filled the aircraft (until post 9/11) and made a profit doing so.

          From a WSJ article in 2003 [wsj.com]:

          "It was a tough decision to make emotionally but the right decision from a business perspective," said Rod Eddington, chief executive of British Airways.

          British Airways has never given figures on Concorde's profitability, but Mr. Eddington said it had been profitable until last year. During the past year, corporate travel on Concorde has declined "massively" as investment banks and other once-heavy users "have been writing Concorde out of their travel plans," he said.

          I have never seen any evidence of subsidisation of Concorde post-privatisation.

      • by Bert64 ( 520050 )

        What made it worse was that a lot of those routes fly over land, where people don't want to hear the sonic booms... Flights between europe and the middle east or asia, flights across the US.. You're basically left with routes from europe to east coast usa, routes from west coast usa to asia and routes to/from australia.
        Even the supersonic Concorde flights from europe has to remain sub sonic until they were several miles clear of the coast which added quite a bit of time to the flights.

    • Concorde couldn't operate profitably because it only had a few routes it could service due to the sonic boom restrictions. Some of the routes that it did originally serve had to be curtailed due to booms. Sonic booms most certainly IS the main problem keeping supersonic flight from gaining a foothold.

        Simple fix: Put all the people who have apoplectic fits over sonic booms but have no problems with thunder in rubber rooms. Thunder over pressure is much worse than Concorde sonic booms. I've lived in the mid west and, as a kid, under the flight paths of the SR-71 and B-70. Sonic booms have nothing on thunder.

        Anyway, Boeing was behind the "ban the bang" campaign when they failed at the SST, switched to the 747 (haul lots of people slowly) and wanted to undermine the Concorde.

      • Totally with you... too bad they contracted Lockheed and therefore nothing will come of it.

        $20 million for a new X-Prize would have been a much better idea. Chances of an X-Prize succeeding is about 50% where chances of a $20 million contract to Lockheed coming to anything other than asking for more money is 0%.

        How many failed projects due to gross mismanagement of finances will NASA suffer before realizing that giving Lockheed money is just never a good idea.
      • Concorde couldn't operate profitably because it only had a few routes it could service due to the sonic boom restrictions.

        Concorde couldn't operate profitably because it was a fuel hog - it used a turbojet which is much less efficient than a turbofan, and it required afterburners (which are hideously inefficient) to take off and to accelerate through the transonic regime. If it couldn't make money on the heavily traveled transatlantic route, it pretty much couldn't make money anywhere,

        • Turbojet is only less efficient than a turbofan when flying at low speeds. At Mach 2 there is not much difference because high bypass turbofans cannot achieve this kind of speed - in fact, the higher the bypass is, the lower is the maximum speed - and low bypass turbofans are basically leaky turbojets which use the bypass air stream more for cooling than for propulsion.

          Yes, the latest Tu-144 used by NASA had turbofans borrowed from the Tu-160 bomber, and they were much more efficient than the Olympus turboj

      If you can get past the sonic boom issue, then it's worth engine manufacturers looking into better engines for supersonic flight. Computer modelling has got a lot better since the 60s too, so a modern aircraft should be able to reduce drag significantly. Higher flight levels are also possible now, which helps thin the air.

      No matter what you do, fuel cost will be higher. It is in the physics of going faster than sound. So it will always be less efficient per passenger mile.

Let's face it, aviation has actually stagnated to a remarkable degree for the last fifty years.

    With all the fun description in the article I did not see any mention of how many people can fly on this. I was never able to fly on the Concorde, though I have walked through the one on display at the USS Intrepid. Walking through it one thing that I noticed immediately was how small it actually was; it took about as many passengers as a large EmbraerJet - and far fewer than a 747 or even 737.

    I don't want to try to oversimplify aeronautical engineering - and I am certainly not an aeronautical engineer myself - but in the current economy it certainly seems that something this expensive will only be viable if it can take a larger number of passengers than the Concorde could.
    • far fewer than a 747 or even 737

      You're wrong about the 737 - the 737-100, which was the 737 variant around when Concorde was designed, could seat 85-124 depending on configuration. Concorde was 92-128. The 747 was only unveiled the same year Concorde was, so again the Concorde design was contemporary with the 707 rather than the 747. The 707 had a slightly higher seating capacity, but it wasn't vastly more. In the 60s, it probably was anyone's guess how things would go - they'd only just left the prope
