www.youtube.com/watch?v=ogYrvEEM0Ts gizmodo.com/gadgets/star-wars/rocket+powered-21+foot-long-x+wing-model-actually-flies-305976.php www.polecataerospace.com/X-Wing.htm Andy Woerner and his crazy rocketeer friends have built a 21-foot long X-Wing model that can actually fly. Yes, this is a real X-Wing powered by four solid-fuel rocket engines complete with radio-controlled moving wings. It blasts off in California next week, and we talked with Andy about the project, and how they expect it will do. All the details and a full construction gallery after the jump. The X-Wing model is huge. At 21 feet long and with a wingspan of over 19 feet it is, in fact, big enough to fly a kid in. However, knowing that it will be powered by solid-fuel rockets, they wouldn't put a kid, dog, monkey or Gizmodo editor inside, even if it uses three full parachutes to land. After drawing the plans using CAD software, Andy's team and his friends at Polecat Aerospace used laser cutting to make the pieces out of Baltic Birch wood. They also used solid aluminum for some parts, like the rods which are the pivot point for the wings. Why solid aluminum rods? For the most impressive part of the project to work, not only does the axis have to be strong enough to support the stress of the launch but also it has to allow the wings to change position from folded to open while in flight—or, in the words of Red Leader, putting them in attack position, the X that gives the Rebel aircraft its name. The wings, including the root sections and the outer panels are about 8' long and weigh 60 pounds a piece, including the motors. The motion mechanism had to be able to move all four of these simultaneously, while keeping them in position relative to each other. Additionally, the motion hardware had to be strong enough to keep the wings in position once they were at the extents of their travel. They used an electric motor from a RC helicopter, reducing its 40,000 revolutions per minute to generate enough torque to move those massive wings. Still, the wings will take 35 seconds to travel from open to closed. Hopefully, they will be able to change before the flight ends, so they can get the full effect in the air. The wings also hold the engines. Andy told us they are using "four solid rocket motors which are Class M, the kind that produce a red flame"—which as you probably know, it's also the same color of the X-Wing engines' glow. Even with the aluminum rods, however, there's the possibility of structural damage. We asked Andy about how he expected the flight to go: "it's likely we will have a structural failure in the wings, but we are hoping it will hold." If it holds, the X-Wing will be fully recoverable. It won't land on its own, but Andy pointed out that they "will use parachute recovery, with three man-rated chutes which will have radio control deployment," like the wings position control. When I first learnt about the project there was one thing that didn't click for me: why the X-Wing? It doesn't seem to have the right shape to be a rocket. Maybe a better option would have been an Y-Wing or A-Wing. But an X-Wing? Well, according to Andy, "it was the one design from Star Wars that made the most sense to try to scale for rocket power." And on top of that, it just looks cool. I completely agree. The X-Wing will launch next week, on October 10, and we can only wish the project the best of luck. Godspeed Andy and friends, godspeed.

Anything with enough power (such as rocket or catapult power) will fly. The key would be if it would have controled flight.
|
|
Now if they only made a model of the U.S.S Enterprise-E that will fly...
|
|
With rocket engines anything can fly.
Look at this model: Is it a boat? Or a plane? Click this and discover |
|
Have these people ever actually seen a Y-wing or an A-wing? Yeah, I can see that they are going to get a lot of lift from a Y-Wing. I suppose an A-Wing MIGHT be able, with modifications, to generate some body lift... At least an X-Wing looks plausible from an aerodynamic standpoint. |
|
|
No, that would be ghey. X-Wing = Cool Silly Star Trek ship = ghey. |

It's not flying, its big shoved through the air. The wings are not generating lift, and there are no control surfaces.
Lets see it do a pylon turn.... |
|
"Controlled" is the key word here kids. |
|
|
I LOL'd |

+1.. |

Those Estes Star Wars models were NOT well thought out. We had a Y-wing rocket that made several slow loops at an altitude of about 25' before smashing itself into the side of my brother's van. |
|
|
I dunno, that sounds a hell of a lot more exciting than any Estes rocket I ever launched. |
||
|
I hope they have good liability insurance (or are
|
|
No problem, it was getting to be a hassle to fly anyway. I had to get FAA clearance when I wanted to launch it, since I'd often break 12 thousand feet. ETA: kind of a waste of post 6k. |
||||
|
reminds me of the one I used to fly a long long time ago.....
|
|
that SOB told me he gave me all the photos/negatives that existed!! |
|
|
LOL 12,000 ft? Damn. Where can I get one of those rocket engines? |
|||||
|
+1 I used to love watching the look of anticipation turn in to a look of horror when one of my buddies rocket creations didn't fly as planned and either blew up, landed in the bed of a passing truck, or just crashed because the chute melted... Oh good times, good times... |
||||
|
Where? |
|
|
So are they going to launch this thing vertically or at an angle? I'll need to know to figure out how deep to dig a safety bunker.
|
|
"Wow, two firsts in one day! This is the greatest day EVER!" |
|
|
If you'd looked at the web site, you'd realize that these guys run a company that makes kits for large model rockets. This model lets them push the envelope a bit, get some publicity, and have some fun. It's a win no matter what happens. |
|
|
In Thrust We Trust!!
That thing needs a bunch of boost to get up, and I am curious to know how the control the X-wing after the rockets flame out. I bet all the R/C does is pop the parachutes. BIGGER_HAMMER |
|
The phrase "as aerodynamic as a chandelier humping a platter" comes to mind. |
|
|
I wonder why they're even messing with the opening wings. It takes 35 seconds, so it's not going to be a dramatic thing like in the movie. They should just launch it twice, once closed, once open. I also think that the moving wings are going to jack up what little aerodynamics that thing has.
It is way cool though. It would rock to have that sitting in my driveway! I mess around with model rockets every few years. I found them to be a cheaper alternative to my old hobby of crashing RC airplanes. now that you can get them cheap at wal-mart and target, I just go buy one of the little pre-build AA models and launch kit, pick up a few extra engines, go spend a couple hours in a field, and I'm good for another few years. |
|
And it will be the R2 unit! |

|
In all seriousness, I cannot see flight possible. With all that fin/wing area at the rear, it probably will be an acceptable rocket, if the CG is far forward.
Unless the wings actually move forward at apogee, the most they can do is guide its downward auger. There is very little comparative lifting body in the forward section. |
|
What if they launch it horizontally, from a treadmill, that moves in reverse as fast as...
|
|
Looks to be not too far from full-scale (admittedly, it's been a while since I've seen the full scale model).
Which one from the picture is going to be the poor sod they're bunging in the cockpit? |
|
Geeks...
But then again at least they make something out of their fantasy. |
