New Supersonic Jet Test Less Than Successful 259

Posted by michael from the seat-cushion-can-be-used-as-a-flotation-device dept.
saberwolf writes "The BBC is reporting in this story that the first test of Japan's supersonic jet didn't go quite as planned when it crashed into the ground seconds after takeoff on its test rig. It looks like a successor to the world's only supersonic passenger jet, Concorde (built jointly by the British and French in the 1960s) is still some way off." Reuters has more pictures.

    • It also appears as if the Woomera test range is not the place to test things that fly if you want to take it home later.
      Today's failure was the second project to experience recent difficulties at Woomera. Last October, an experimental rocket crashed after its guidance fins moved during flight and sent it off course following its Woomera launch. The rocket, the Hyshot scramjet being developed and trialled by Australian and British designers, was supposed to have gone to an altitude of 300km but only reached 61km before it crashed.

      It could have been either the jet or the rocket that caused the failure, as both would need to use their control surfaces to keep the flight stable. Set a fin or a flap the wrong way, and you go spiralling into the ground. Which looks a lot like what happened.
      • Depends, in the Hyshot test last year, from the same launchpad last year, A fin came off the second stage, also wiping out a fin on the first stage, as the rocket came off the pad. This test still made it to 60-odd km altitude, and this rocket was spin-stabilised.

        I doubt (though I don't know) that this rocket was spin stabilised, simply because the payload was non-symmetric, and spin-stabilisation would have greatly added to their problems. My guess would be either some mechanical failure (the rocket broke in half), or the gyros failled in some fashion, under the high force of ignition or takeoff. Failure of the gyros is far more likely.

        I always find it amazing just how high the failure rate is for what should, after 50 years, be routine rocketry.

    A booster rocket was supposed to take the craft up - and then the craft would glide supersonically down.

    • It crashed a few seconds after takeoff - so it can only be the booster rocket that failed - right?

      The booster rocket provided the thrust, but the plane was big enough to drastically affect the aerodynamics (it was bigger than the rocket). A control systems failure or mechanical failure on either vehicle could have caused the accident. I'm sure there will be a press release when they figure out what exactly went wrong.

      This plane is designed to be bigger, faster, and have far better fuel efficiency.

      It's a very different design, and so of course has to go through a lot of testing. Even aircraft based on more conventional technology have to go through this (you don't think they'd put, say, a 747 on the runway without doing test flights to verify the design, right?).

      The ony down side to this test is that they won't really learn much from it. The craft or booster failed while taking off, not when cruising under flight conditions.

My g/f and I called up some of the companies, and asked them about their accident record, before picking which company to fly with. Luckily we had some outside info, otherwise we'd never have been able to tell anything at all about their safety records. One company, which had had multiple fatal accidents, would only acknowledge that "yes, they had had some 'incidents'". Further questioning resulted in evasive answers about things like the safety improvements that had been made since then.

      As a kid I often stayed at my Grandfather's place on [multimap.com]
      the north coast of Cornwall (non-UK readers: the 'foot' that sticks out of the UK to the south-west.) You'd often hear the sonic boom from Concorde accelerating through (or decelerating back through) the sound barrier above the Bristol Channel. It sounded like a distant roll of thunder on a hot summer's day. (Of course it was always hot and sunny back then... </nostalgia &gt& .) This location was at least fifteen miles *horizontally* from the point the boom originated; I don't know the height they'd do this, but the point is sonic booms from something big enough to carry passengers carry a *long* way.

      Nowadays, I live in South London [streetmap.co.uk], which happens to be on the flight path for Heathrow (along with most of the rest of south/west London...). The windows are double-glazed, which makes a nice Concorde test: when you can hear aircraft noise indoors, it's *always* either Concorde, or a low-flying police surveillance camera. (We live in a police state over hear, because guns are illegal. Gosh, how I wish I lived in the USA, so I could defend myself against the crushing power of the State! < /troll > ) I usually pop outside to watch it pass overhead if I have the time, 'cos I grew up somewhere where aircraft were either contrails, or Tornados, Jaguars and A10s practicing low-level flying: these split the sky open and were gone usually within 10 seconds, rarely long enough to get much of a look. The difference in noise level is very noticeable compared to the usual commerical widebody heavies flying at the same altitude (?5000 feet?). It's also noticeable how long and slim Concorde appears compared to a 747 at the same altitude; it appears to be perhaps 60% of the size, and the fuselage is barely discernable; on a modern stretched 747, you can easily distinguish upper and mid and lower-deck rows of windows.)

      The reason the Concorde is so damn loud are the Rolls Royce Olympus engines. They're optimised for supersonic flight, which makes them horribly inefficient -- they have to burn a *lot* of fuel to provide reasonable thrust at low air speeds (and given the airframe's delta-wing profile, "low speed" is relative: I haven't the numbers, but she takes off and lands *very* fast. Most supersonic military aircraft for the last 20 years or so have had variable geometry flight surfaces (BAE Tornado, f'rinstance, or the US Tomcat. Or that fskcing GORGEOUS Russian aircraft with the twin air intakes below the fuselage... but I digress) - the wings are swept forward for low-speed operation, then back into a delta configuration for high speeds.

      This is another reason the Concorde's so expensive to run, which was another factor in it's commerical (lack of) success. Now, what I'm wondering - and I'm slightly puzzled why there hasn't been a /. story on this - what will happen to the competing next-generation passenger aircraft planned by Airbus and Boeing, pre-9/11? IIRC Airbus had settled on a 'superjumbo' carrying 700+ passengers, and Boeing had taken the brave - nay, reckless! - decision to go for a "super Concorde", a high-volume production, wide-body, supersonic passenger aircraft, carrying 250-400 passengers (compared to the original 60's version, with a maximum of ~110 passengers and crew.)

      Anyone able to enlighten me on this?

      • By the time these jets actually start to enter production, 9/11, while it'll hardly have been forgotten, will be long ago enough in the memory that the impact it's had on air traffic will have disappeared. Additionally, the US economy should be out of recession by then. Heck, *Japan's* economy might come out of the toilet by then.

        Oh, and as another poster has pointed out, Boeing's current toy isn't supersonic, it's just high subsonic (~Mach 0.95 rather than the standard ~0.8).

      • The sonic boom does not occur as an aircraft passes through the "sound barrier." The boom is the passage of a shock wave from a supersonic aircraft, and the shock wave exists as long as the aircraft is supersonic. The shock wave can be thought of as the sound trapped in a thing cone because it cannot go faster than the aircraft, so it all "stacks up" in the shock wave.

        For example, when the Space Shuttle landed at White Sands, New Mexico, we heard the double boom as it went by Phoenix, AZ. It was still supersonic at the time.
      • I don't know the height they'd do this, but the point is sonic booms from something big enough to carry passengers carry a *long* way.

        Concorde cruises at 55,000 feet, +/- 5,000. It has to fly that high so that the air density is low enough to reduce friction heating to an acceptable level. Only once it's flying subsonic can it descend to lower levels.

    • Any plane flying at hypersonic has multiple sonic cones - plane, engines, etc. These can be placed so that they extinguish each other due to interference patterns. This means that from another viewpoint they will amplify each other. If the "another" point in question is above the plane it is a "who cares about the dead fish" case.

      On a different note, Concorde is hellishly noisy when subsonic. It is the bigger problem (most of the flight is above water). Unfortunately this problem is quite hard to solve as all recent development into noise efficient engine shapes (new boeings, new airbus, new engines on russian jets) has gone into subsonic turbofans. The knowledge from these cannot be applied into hypersonic engines right away.
    • Or are they just referring to the noise level when in subsonic operation?

      You obviously havn't heard concorde flying subsonic. It must be the loudest civil aircraft by a long way.

      In which case, like the Concorde, it could only go supersonic over water... but then how could it "operate far more widely" than the Concorde?

      The want to fly this between Japan and the US. LAX is more or less due west from Kansi. With nothing other than the Pacific in between. They also want to make a supersonic airliner with much greater range, since there is no way Concorde could cross the Pacific without finding places to land and refuel.

    You seem to be forgetting the Tupolev TU-144 [www.bird.ch], dubbed Concordski in the west due to its uncanny resemblence to Concorde. Although faster than Corcorde, its crash at the Paris Air Show effectively put an end to its challenge to Concorde in the commercial marketplace. Nonetheless, it was used as a passenger carrying jet in the Soviet Union in 1977 and early 1978 until another crash put and end to its career. Concorde is, therefore, the only currently operating supersonic passenger jet.

    • You seem to be forgetting the Tupolev TU-144 [www.bird.ch], dubbed Concordski in the west due to its uncanny resemblence to Concorde.

      Apparently Tupolev copied some aspects of the design. Yet there are differences such as engine placement and the retractable cannards.
      In terms of speed, payload and range the TU-144 is a superior aircraft.
    • The Paris crash was actually caused by a French Air Force fighter interfering in the Tupolev's flight path. The Russian pilot (a highly regarded test pilot) overstressed his plane while trying to avoid hitting the Dassault Mirage, which was not supposed to be there. [pbs.org]

      I don't think Tupolev ever planned to offer the 144 on the open market.

      Most of the asessments I have seen seem to think that the Tupolev in its final form had a superior airframe design overall, but terrible engines. NASA purchased a TU-144 as a test platform. Last I heard, that unit was for sale [biztobiz21.com] The asking price was $10, 000,000 IIRC. I believe it is the only currentl flying 144, although there are eight complete airframes in existence.
    • I gather the engines were not as good as the Concorde. Concorde had the Rolls Royce Olympus engines - superb, old design first used on the Lightning, and susequently on th Vulcan [uk0.net].

      I heard that the Tupolev TU-144 needed afterburners to pass through the sound barrier, and possibly also to remain there.

      It is quite difficult to design an engine that must have all air going through the engine at subsonic speeds, for the air surfaces like turbine blades to work, and yet propel the plane at supersonic speeds. Think about it.

      The answer is the nozzle at the back.

    From my limited observations of the Reuters photos and BBC video clip, it appears that the booster rocket left the pad without the test glider. Immediately after leaving the launch rails, the booster tipped over, indicating that there was an unintentional mass imbalance (hence, gimballed boosters counteracting a non-existent payload) that threw the flight path out of whack. Can anyone tell whether the rocket flopped away from where the payload should have been, or in another direction. If it fell away from the payload, the payload must have become unattached.
  • It takes more than desire and a theme song to master the laws of aerodynamics. Here's an example of a bunch of talented and dedicated individuals doing something they've been trained for, and there still was an unexpected failure.

So double that and you get 12,000km, or 7457 miles, which would put it out of reach of the ten longest commercial air routes [zyworld.com], including service between California and Australia. But I guess Japan isn't too concerned about that particular route :-)

    At least service between the U.S. East Coast and Tokyo would be cut from the current 11 hours on ANA [fly-ana.com] down to a much more tolerable 6 hours.

    I've just seen an Australian news broadcast with interviews of the parties involved and they say that the model separated from the rocket at lift off.

    The indication was that the model fell back onto the launch pad and the rocket then went out of control.

    And the winner on the day was: Sir Isac Newton!
    • I wondered about that when I saw the shots of the rocket shortly before it hit the ground (no, not on the pad - 10 seconds later). In the photo of the assembly on the pad you can see the wings of the model, but in the final shots, even the ones in which the rocket is shown spiraling in the sky, the model isn't visible.

      If the guidance system is programmed assuming the model is attached, and the model is not, it may not respond very well.
  • My farther is the range operator at Woomera and was present for the recent test's. It was the rocket delivering the payload that failed rather then the payload itself.

    If the rocket had managed to deliver the payload it would have been a huge step forward in the design of air craft as the model had been computer generated skipping the whole process of wind tunnel testing etc . . .
