Coolest Model Rocket Evah!

Whoa

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.

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.

They launch on October 10th.  Man, to be there and watch this thing fly.

Not that very many people ever read this far down, but this blog was the creation of Allan Kelly and his friend Vilmar. Vilmar moved on to his own blog some time ago, and Allan ran this place alone until his sudden and unexpected death partway through 2006. We all miss him. A lot. Even though he is gone this site will always still be more than a little bit his. We who are left to carry on the BMEWS tradition owe him a great debt of gratitude, and we hope to be able to pay that back by following his last advice to us all:

1. Keep a firm grasp of Right and Wrong
2. Stay involved with government on every level and don't let those bastards get away with a thing
3. Use every legal means to defend yourself in the event of real internal trouble, and, most importantly:
4. Keep talking to each other, whether here or elsewhere

It's been a long strange trip without you Skipper, but thanks for pointing us in the right direction and giving us a swift kick in the behind to get us going. Keep lookin' down on us, will ya? Thanks.
