X-Wing Rocket Launches, Disintegrates

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.

    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

    As much as I loved the idea, these people were not engineers or this would never have happened. For all the jokes about "rocket science," reliable rocket design isn't that hard. The forces from the engine are known from the manufacturer, the aerodynamic forces are relatively easy to estimate, checking stability is simple (basic childhood rocketry books tell you how), the forces inside the structure aren't that hard to work out, and the material strengths can be looked up or discovered with a few tests. The point is that engineering lets one design something that just works. Sure, if one really wants to push the envelope on performance (e.g., the highest performance engines on the lightest possible structures), then it becomes necessary to do some testing, but by the time a full-scale model is done, the chances of success should be fairly high (and the risk of failure known).

    With a bit of thought, pencil, paper, and a calculator (or slide rule) these folks could have built an X-Wing that really flew well again and again. But perhaps that wasn't their goal. Sometimes the goal is just to watch stuff blow up.

      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.

      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.
