 The "Coney"

The rocket in the picture to the left is based on Robert Youen's "Coney."  This is a backslider or back-gliding rocket.  Robert and Peter Alway did extensive research and obtained a patent on backsliders.  Their work was done with a 55 diameter long rocket and their patent references a 30:1 and 50:1 length.  Robert Youen's Coney (and the one pictured here) is 12:1 and is not tubular in shape so the effective ratio is even less.  The result is that even when properly built and precisely balanced according to the Alway report, it is not dependable.  Click on the picture or here to see a wmv, 12 second, 0.5 meg clip of how a "perfect flight" can go wrong.  The clip is about 12 seconds long.  At 9 seconds it disappears (into a black hole?) for a second and then reappears falling vertical and accelerating into the ground.

However, in the book, I give you the correct balancing location for this rocket to backslide correctly.  Click on the links for the "real" perfect flight.
