Ring-wing glider

[sooner.boomer]

Has anyone seen/built a ring-wing glider? Not a single ring like the Stovepipe, but one that used a pair of rings (or more properly cylinders). There's a Canadian company selling a hand-launched glider called the "Skyaak" http://skyaak.com/tag/skyaak-ring-wing-glider/. This actually uses two cones rather than two cylinders. About 10 years ago, a member of the local NAR group had built a glider from two carbon fiber cylinders and a carbon fiber arrow shaft. I'd like to duplicate the design (lost contact with original member). I've gathered a lot of stuff to go through from NACA/NASA documents, but would like to hear if anyone else has built something like this, or if they have comments/ideas.

It looks like 2 lamp shades on a body tube.

Yes I've built a few small ones using straws and card stock. Also one of the Whitewings sets had one in them.

There was also a rocket glider design printed in Sport Rocketry a while back that was a two ring wing type. Had "hawk" in the name I think.

A similar design, Tim Bush's Ringhawk plans are printed in an old MASA newsletter here: http://www.mn-rocketry.net/masa/planet/masa_Vol6-5.pdf Page 4

I have built one of them, and it is a fun little flyer. It currently needs re-building, due to hangar rash.

These Straw rocket ringwing glider do quite well. Lots of indoor or outdoor fun.

Which end is the "front"? Do you have build details? I ran across something like this in my web search. Is that a Nike Smoke?

The smaller end is always the "front" LOL!
the strips are simply computer paper or copier paper, the rear 1-1/2" wide x 11" long, forward 3/4" wide by 6" long. make a loop out of each taping the end with magic tape, then tape to a standard drinking straw.
Adjust the Glide trim by moving the forward ring back until you get a nice level glide. For hand tossing the straw can be left open on both ends, for launching from a soda bottle fold the forward "Nose" closed and tape.
I've been simply amazed at the altitude and distance one of these little ring gliders can achive outdoors from the sudden squeeze on a 16 to 20oz plastic soda bottle. 12 to 15 feet up with a glide of more the 50yards. They just seem to hang in the air and slide along LOL!!!

If your speaking of the red tapered point model second for the left in the first phot no it's no a Nike-smoke. It's my own design I just call it the Conehead Paper rocket. That one I do have a page plan for the other two that are a blast are the little straw launcher ALCM and 2-liter bottle squeeze launched 10-1/4" paper rocket. Great paper and tape fun for all ages. Super for those "NO-Field or Flyable" demo's.

I downloaded the .pdf and that looks like a neat rocket. It'a got the body tube as the spar, and the front ring slides forward on ejection. The rocket Peter built had fixed rings, and flew (I believe) on a G80. This design has equal-sized rings. I can't remember if Peter's rocket did or not. Also can't remember whether the engine pod was outside the rings or inside. I've found two airplanes that might serve as inspiration as well. One called the "Hoopskirt" from the April '63 Popular Mechanics (google books), and another I found through google images that has a pair of octagons on opposite ends of a main spar, with an engine on a pod below.

Apparently the "Flying Octogons" was designed by Ted Maciag. It came from the web site http://aeromodelismovolarlibremente.blogspot.com/ - a model airplane (powered and glider) free flight blog. Found build plans on google images that point back to this site (in the image). Looks like there might be more good stuff there...

Interesting design concept....
A friend of Trudy's introduced me to the mono-ring glider a while back, but the dual conical sections makes this intriguing.
