Somewhere, Over the Rainbow

My initial mindsim, performed while grasping an old school slide rule and invoking the spirit of Kelly Johnson, is that a lot of slower moving turbulent in the inner arc will produce a lot of lift as the faster moving air on the outer arc becomes turbulent at the bottom, making any fins on the back nearly useless.

Hmm, maybe so. I wonder if a piece of Lexan to "fill" the space inside the arc would help smooth out the airflow. Or, if that's a totally stupid idea. Of course it's all idle speculation at this point.

Hard to say but a mindsim on that level could blow a vacuum tube, thereby jeopardizing your credit rating.

And we're back to the nonsense...

Oh show us the way. Only use pure science and no humor.

Can you post a PIC of this thing yet?

From the above, I still don't get a good feel for what this puppy looks like.

Thanks!

I just want to hear the magic "G" word which will solve all the crooked arrow's problems!

Only have the one piece of the fins sitting with the tubes (and the fin still needs to be covered). Motor mount also not included

I still am not visualizing the structure, particularly orientation of motor(s?) and fins and nose cone.

It would be much better to launch horizontally. Put a Care Bear or Toto on top for a nose cone. Cloud fins on both ends. A pot of gold would make a nice nose cone on a horizontal launch, but a pot of gold on top of the rainbow instead of it being at the end is utter nonsense!

Launching vertically with advanced gimbal technology would approach the magic of the crooked tube Spitfire. Sometimes I forget that the right place for the motor and fins is at the back of the rocket: where they should be!

Y'know, that could really work

Lots of rainbow colored streamers hanging off the cloud fins. Wicked witch nose cone with smoky motor so if it sky writes you can say I meant to do that!
