Thomas Buchwald

Thomas Buchwald is a "Technik" teacher of students in grades 6 to 10 in Germany He is a great friend, though I have yet to meet him in person. Thomas and his students make wonderfully creative engineering projects. Lately he has turned his attention to creating bionic walkalong gliders: pterodactyls (pterosaurs), manta rays and other sea creatures. I particularly like the sea creatures. 

Here you can find the PDF file, including four patterns. It is written in German. "Bergfalte" means "mountain fold"; "talfalte" means "valley fold"; "oben" means "top"; "hochbiegen" means "bend up" and "leicht hochbiegen" means "slightly bend up."

Mr. Chen Wenhwa from Taiwan

I have been admiring the work of a gentleman in Taiwan for a long time on YouTube .Mr. Chen Wenhwa is a primary school teacher who also volunteers at a science museum and works with the Yuanzhe Foundation to promote science education. Chen makes the elegant flying creatures: birds with long, graceful wings, dragonflies, bats, butterflies, etc. Now we are becoming friends--struggling to communicate with Google Translate. I was very happy that he sent me some foam gliders. They are beautiful and fly very well, so efficient that I can fly with only hands.

Here is a nice foam dragonfly glider design. I think it might benefit from bending the back up a little (reflex, elevons) although there might be other tricks for gaining stability..

Here is a good butterfly design.

Mr. Chen Wiz from Taiwan

Here is another gentleman from Taiwan who makes beautiful butterfly gliders.He has some cool videos of ultra lightweight model planes, too.

Alsomitra (Alsomitra macrocarpa)

Alsomitra (Alsomitra macrocarpa), also known as the Java Cucumber vine is a vine with remarkable design for spreading its seeds.


Noel Eberhardt’s Brilliant Folding Jig(and a bit about Noel)

Here is a video that Noel sent of the Portola Valley Community Center “Flight Night”. He said, “These two girls were flying the walk-alongs minutes after making them with no instruction or guidance other than their observation of others flying them. ” Notice the dog observing the fun!

When I first started making thin foam walkalong gliders, I had to tape on a pattern—which took too much time. For years I developed various folding jigs and they worked; but the jigs were hard to make, involved complicated taped hinges and the foam had to be repositioned several times. Noel Eberhardt, a retired engineer in California, took the quest to the finish line! His folder design is elegant, effective and so easy to make and use. It’s a game-changer for people making walkalong gliders with groups.

Apart from this accomplishment, Noel Eberhardt is a case study of Pasteur’s observation of how fortune favors the prepared mind. His life is rich with eclectic experiences and inventions, some of which I’ve written about below, after we look at his procedure.

Even before discovering very thin foam walkalong gliders, Noel was teaching groups of young people how to make gliders from foam plates.

 

THE FOLDING JIGS OLD AND NEW

Here are some screen shots from a video about the old folding jigs that I developed. They worked, but were difficult to make. You can see the early folding jigs in this video.

The back elevon required a different folding jig, so positioning the foam a total of 3 times per glider. By contrast to that, Noel’s design only requires on jig and one positioning of the foam.

Here are a few pictures of Noel’s new procedure. Gallery of full set are below.

Noel uses thin plastic (red) to make a cutting template for the foam
This is his folding jig--hinged with tape. Simple, but so effective!
The foam goes in...
...like this.
The foam is positioned by aligning with the bottom of the jig.
Noel used fingers to bend the camber. Using a flat surface is possible too.
The elevons go the opposite way as the camber.

Make a Tumblewing

Astonishing! You are flying a piece of paper, surfing it on a wave of air created with cardboard. There are many branches of walkalong gliding, but the Big Mouth Tumblewing is the easiest way to start. You only need phone book paper or newspaper. This video starts with a introduction, then instructions for making and flying tumblewings.

More Tumblewing Instructional Videos

Here are some other instructional videos about making the classic, original tumblewings. This one is by John Collins (The Paper Airplane Guy and tumbling wing inventor).

Here are some by Phil Rossoni.

And here is Phil's Instructables page.

Once you master making and flying tumblewings, the next logical step is foam gliders.

I'd like to know how this project goes for you. I'm happy to answer questions about it. Feedback from you is an important way for me to know what works and what needs clarification.

Make Paper Walkalong Gliders

Dihedral Magnus Effect Gliders

There are many branches of walkalong gliding, but the Dihedral Magnus Effect Glider is the easier way to start.

Tumblewing

It's harder to fly than the other two, but it's good practice.

Origami Hang Glider

These are very difficult to get right. Unlike the spinning gliders, Origami Hang Glider is an advanced project.

Next to the dihedral magnus effect glider, the Big Mouth Tumblewing is the easiest way to start flying a walkalong glider. You only need phone book paper or newspaper. The pattern here.  This video starts with a introduction, then instructions for making and flying tumblewings.

"Flying Fish" or spinning blimps are simple and quick to make, and you can fly them as walkalong gliders.

Make a Baby Bug Walkalong Glider

This video is a little rough, without sound, but the method is much simpler and faster than the old way. Also, the way to find the balance between stalling and diving is clearly laid out. The PDF cutting/folding pattern is here--no "fit to page" or scaling (100% scale is ok).

Make the Thompson Jagwing

Invented by a then engineering student named Michael Thompson, the Jagwing is a good first walkalong glider.

About Front Weight

Why you need front weight on "flying wing" gliders, what to use, and how to adjust them.

Make Paper Walkalong Gliders

Paper Walkalong gliders are harder to launch and fly. But paper is free and it’s good practice.

If your glider is attracted to the board…

Static Cling and Walkalong Gliders

Even though this video is not fully completed, it shows how to work around static cling, avoid it or discharge it.

One day I tried to demonstrate air surfing in a classroom. It was not working. When the air-deflecting board got close to the glider, they were attracted. I finally figured out that static electricity was causing the problem. That time it was because the room had carpet. It can also happen when people unconsciously rub the boards against their clothing--particularly when the weather is cool and dry.

Here are some ways to get rid of static charge. Rub the board with a wet rag or something. Dampness kills static. If the glider itself has static charge, then hold it in the steam (actually water vapor) over a bowl of very hot water. You can dab it with a slightly damp washcloth, but if it gets wet, you'll have to let it dry. Just a few drops of water will add too much weight.

If you do not know how walkalong gliding/air-surfing works, this might be confusing. Walkalong gliding does NOT use static electricity at all; it only uses deflected air to levitate gliders. However, you can use static electricity to levitate tinsel, thin plastic, etc. There is even a toy that is a hand-held Van De Graaff generator that makes things float. And to make things even more confusing, static electricity can attract AND repel things.

So of course by now you are thinking, "Why not combine aerodynamic with static levitation. And indeed my friend Nyle Steiner has done some work with that.
