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." "
But shreds are not uncommon in high power rocketry.
I'm sure they'll learn from the failure and build another one until they get it right.
That's pretty much the whole point of the hobby. If you don't have the occasional spectacular failure, you're probably not innovating enough.
The overall design of the x-wing serves one purpose: to look cool in a movie. Don't overanalyze. Accept it for what it is.
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?
