Glider help

[blackshire]

Hello All,

Below are links to printable cardstock gliders, cardstock model rockets (including a two-stage one), and even a cardstock altitude tracker. These were all developed by a New Mexico unit of the Civil Air Patrol (CAP). But first:

For those of you who have been having difficulties with getting boost-gliders to fly, Norman Schmidt's book "Fabulous Paper Gliders" (see: www.abebooks.com/servlet/SearchResults?an=Schmidt%2C+Norman&sts=t&tn=Fabulous+Paper+Gliders ) can help. It contains "scan-able/photocopy-able" patterns for simple, flying scale models of historic gliders, which the readers can make from 110 pound cardstock. Complete instructions for building, trimming, flying, and even storing the model gliders are provided. The illustrated text describes each glider and explains (with accompanying drawings) how motorless aircraft work, including lift/drag ratios, the different types of soaring (slope, thermal, and mountain wave), the finer points of trimming full-scale gliders, etc. The history of soaring and the pioneers of soaring (Lilienthal, the Wright Brothers, etc.) are also covered. This is an educational book that was written for school use, so teachers will also find it useful. Also:

One simplification not mentioned in the book (because scanner/printers weren't ubiquitous then) is that instead of photocopying the glider parts' patterns, cutting them out, and then gluing them to cardstock sheets, the patterns can be photocopied directly onto 8-1/2" X 11" sheets of 110 pound cardstock (which is available at office supply stores, Wal-Mart, etc.) and then be cut out to assemble the gliders. If the 110# cardstock sheets are fed through a printer/scanner one sheet at a time (not stacking them in the paper feed tray), this works just fine--that's how I print on cardstock using my HP PSC 1210xi all-in-one printer/scanner/copier. Below are the CAP cardstock glider, model rocket, and altitude tracker links:

I hope this information will be helpful.

Those would be good with balsa or foam core too!

Here is another link [LINK (http://cp.c-ij.com/en/contents/2023/03274/index.html)]. It is actually a pretty nice little glider.

For a while, these were sold in the U.S. with Balsa fuselages. They flew just fine.

________________________________________Indeed--those could even be laser-cut to produce them (and the cardstock wings and tail surfaces) in quantity. A low-powered boost-glider (just using 1/4A or 1/2A mini motors) might be able to use glider designs like these.Here is another link [LINK (http://cp.c-ij.com/en/contents/2023/03274/index.html)].

It looked vaguely familiar...and sure enough, it's one of Dr. Yasuaki Ninomiya's WhiteWings (see: www.whitewings.com/ ) designs; I may even have the WhiteWings glider assortment that includes the Racer 538.

Also, I just found a page on the WhiteWings website that includes their WhiteWings "Trainer" 'Tune by the number' glider kit (see: http://shop.whitewings.com/Educational_c11.htm ). This kit, as well as Norman Schmidt's book "Fabulous Paper Gliders" (see: http://www.abebooks.com/servlet/SearchResults?an=Schmidt%2C+Norman&sts=t&tn=Fabulous+Paper+Gliders ), can help those who have problems getting boost-gliders to glide to understand not only *how* to properly trim B/Gs, but--just as important--*why* the proper trimming techniques work. Since a front-motor boost-glider is essentially a hand-launched "chuck glider" (as G. Harry Stine pointed out in his "Handbook of Model Rocketry"), knowledge of such gliders is directly applicable to designing, building, trimming, and flying boost-gliders (including parasite B/Gs).
