Goonieprise GNE-1701A The next Generation

[les]

I contacted Alan to purchase copies of his 3D printed parts. See his Goonieprise thread here Goonieprise

I didn't want to hijack his thread, so here is my version. I made a few changes.....
I've been doing this in the background from my Tri & Quadra Dent builds

Main changes:
1) Made the shuttle a bit more 3D, plus plan to invert it
2) Moved the warp cores out.

First the shuttle. Googling the Galileo it looks like this.


So I added the mini-wings

Cut some popsicle sticks to make supports. I used a 3/16" lug as a spacer



The attached the engine pods

I glued 2 craft sticks together to make the engine supports. These will be mounted TTW. The second pix they are just dry fitted.



I did decide to airfoil the internal portion of the supports.

 

[les]

This is where I am as of tonight.
Dry fitted all the parts (or holding the shuttle). You can see how I plan to "invert" the shuttle

I am sticking by my propulsion units.

still think the forward nacelle grid (and now through the wall fins) convert perfectly good ring fins to flat draggy cylinders from an aerodynamic standpoint.

I’d keep the front pieces for display, but remove them for flight.

 

[les]

The front pieces are not glued on, so I can remove them. And I did airfoil the "through the wall" fins

Although with the shuttle being inverted, I wished I had thought ahead to make it TTW as well
I think I'm going to use that shuttle/tube joint for the lug, and put one on each side......

After all - Symmetry is important, right???

 

[grapetang]

Why not make the shuttle boxy with opened fore & aft so you have a rectangular/hexagonal tube fin?

Or change it to the Botany Bay in the proper tractored position?

Going with TTW for the shuttle

Cut a slot. made a tab, glued in, and filled

 

[les]

Added about 2 oz of weight into nose cone. Sorry - no pix of pouring BB and epoxy mix....

And primed

 

[BABAR]

Any man who could perform such a feat, I wo'd na dare disappoint. She'll launch on time. And she'll be ready.

 

[les]

'Tis silver now....

 

[les]

Ready for flight. First flight I will remove the warp engine covers....

I flew the rocket at the URRG launch today. Not certain whether it was my design changes, or the added nose weight, or the fact that I flew it on a D21, but it appeared to fly straight. I say "appeared" as Scotty kicked it to Warp 9! It was on the pad, then it was just UP!!! Note that the body tube is very short and I had difficulty fitting the chute in, which is why there is a slight gap at the nose cone joint. I did fly it without the nacelle covers. If I was to ever rebuild it, I would add at least a half inch of length (which would also assist in the stability)



After all the other rocket flights, I went back to refly it with the nacelle covers installed. I used the same motor so I only changed one variable at a time. I did notice that some of the external paint on the main body tube "bubbled" from the heat. What I failed to notice is the heat also damaged the shock cord. The cone separated, but everything landed ok with only minor damage that is easily repairable
