X-Wing Rocket Launches, Disintegrates

An anonymous reader writes "Remember the 21-foot X-Wing with four rocket engines? It launched yesterday from Plaster City and here's the video showing what many thought inevitable: total destruction in mid-air. From the post: "I can only say two things. The first is: absolutely amazing. And the second: poor Porkins." "

    That kid really enjoying the destruction is pretty funny.

    For those who'd like to do something similar but on a much smaller scale, Estes has done a number of smaller model rockets based on the Star Wars movies. A couple decent models are R2-D2 and my favorite, Vader's TIE fighter. But I would guess the most appropriate to this discussion would be the X Wing

    I've often been amazed how bad the aerodynamics of Science Fiction are. The X wing is a pretty good example, with those huge laser weapons on the ends of the wings that guarantee flutter problems in the wings. I also find it hilarious that the leading edges of the wings are flat. Then there's the silliness of having 4 engines instead of two. The whole problem is instead of being practical, science fiction spacecraft are just there to look cool. If the rebels can't figure out a few obvious improvements like these then they deserve to be crushed like a bug by the Emperor.

      profanity in the presence of minor is hilarious.


      If he had said "Jesus Christ" it would have been profane. In this case we have common place vulgarity, from the Latin vulgris, of the common people, which leads us to the humor of the situation:

      What is hilarious is an adult acting in the way everybody is commonly known to act, but from which children are enjoined.

      On the other hand, one might observe that the word "profane" often refers in sociological contexts to those matters which are of an ordinary, day to day nature, as opposed to the sacred which is outside the realm of ordinary experience. Therefore one may learn the profane through observation, but the sacred is primarily learned through other people.

      Thus, that the stars exceed Man's grasp is a profane fact; that Man should reach them is a sacred opinion, which is the moral of today's ironic shaggy dog post.

    That was lame. Even if it hadn't disintegrated early, it was on an arc that would have hit the ground in about five seconds.

    Now if they'd built it as a large R/C model aircraft, it would have been cool. That's been done in a 24 inch wingspan model, so it's possible to fly that shape.

  11. Re:Too bad they weren't engineers by Rich0 · · Score: 3, Interesting

    I think it depends to a great degree on how far you're pushing the envelope.

    The early rocket experiments didn't have general guildlines to go from - and so they discovered problem after problem by experiment.

    They also didn't have parts with known specifications - they were building their own engines which were often sources of problems.

    An amateurer rocket designer today can buy off the shelf parts - and know exactly what their tolerances are. If their engines are certified to produce x N of force +/- y% then you can simply design for that. If they have a 99.99% reliability rate you don't need to worry about them just blowing up.

    To me this whole thing sounded more like an exercise in amusement than trying to actually get a rocket off the ground. Nothing wrong with that - but it is hardly big news when the thing disintegrates in mid-air...

    As much as I loved the idea, these people were not engineers or this would never have happened. Yeah, that much was obvious, I thought, from the pics linked from the original article. The thing was simply a scale model with rocket engines tacked on. The first thing I thought when I saw the build pics was "baltic birch and aluminum rods? It's going to fall apart." Just an eyeball reckoning of the stress vectors between the body and engine attachment points reveals a half dozen points of guaranteed failure. I think it's funny that they even bothered to put a parachute system in it.

    No Kidding.

    The stuff they did with Boston after mounting it on that guitar-shaped spaceframe are really impressive.

    Reentry capability after interstellar flight was a necessity, while hovering on pressor beams simplified the search for a suitable landing area. The asteroid clearing capabilities made manouvering in planetary ring systems possible and the debris shielding was impressive. Needed a little boost to get out of the atmosphere, though.

    The early prototypes weren't as sleek but worked pretty well, too.

    1. Re:clearer vid of the launch by OmniGeek · · Score: 3, Insightful

      Seems pretty clear from your (excellent quality) video that one of the wings (near left side from camera POV) bent outward, forcing the bird to arc toward the camera and ripping the rest of it apart.

      It appears that had the airframe survived, the rocket motors would have boosted it to a respectable altitude, based on how far it got.

      I'm shocked to see people standing so close to the launch point that they had to run from the falling debris; this bespeaks an insane lack of safety-consciousness by the operators (especially given their expressed doubts as to its surviving the launch.) They're fortunate no one was maimed.

      With a much stronger wing-root design, they would probably have had a successful flight. The RC model sailplane design approach of a foam wing core, fiberglass cloth skin, and carbon-fiber wing spars might be used to good effect in such a design (lighter weight, more rigid wing). Having the rocket motors on the swings DOES add stress to that region, but that shouldn't be a show-stopper; the stress from drag on the wing (and from any flutter instability) is the major design issue there.

      Neat project, for all its problems. I wonder if they'll try again?
