JAN2003: Landing Wire Quick Release Pins


File node-a33.html My own version of the quick release pins as seen above differs a little from the original, but keeps the basic function. I just have used material that I already had instead of buying new. The original will look a lot better and have a more secure locking method, using a spring. This is the original drawing, recommended for anyone who wishes to make these pins:


File node-c04.html At this point, I only knew "it is going to have two wheels, no matter what".

More than a year later, I can say these real aircraft wheels are way too small and way too expensive.

Lesson learned:
Mike is right. Now there are two wheelbarrow wheels...

Easy: just remember that clicking the topmost slide on each page will get you to the next page.
In the end you will always get back to the introduction, which in turn gets you back to the table of contents.

Now click the slide (the compass) to proceed to the next page.


File node-i03.html The BUG2 is a Basic Ultralight Glider. The design, and especially the CAD files were given away for free by Mike Sandlin, a priceless initiative. Without his engagement I still would be sitting on the couch, dreaming of how to make an airplane. In the meantime there are also drawings for BUG4, and these are by far superior to BUG2, lots of small but important changes.

The above image is from Mike sandlin's web site, http://home.att.net/~m--sandlin/bug.htm which I recommend as the source of information.

My own version of the BUG2 incorporates a second wheel and the changes to the design have been large, crude and nothing is tested as yet. To make this unmistakingly clear, I have not intended to improve the original BUG design in any way. My own objective is that I want to learn what it takes to design an airplane, and in the process I have made and will make errors. I have not copied anything until I felt I have understood the reason for why it has been designed the way it is. Since time is going on, there is no easy way back to the original, even if I wanted to.

These pages are most useful for you if you are already building a BUG4 and want to see how things come out in the end. I have learned a lot from the differences between BUG2 and BUG4, and you may learn from the differences from your BUG4 to my rather crude imitation of a BUG2. If you have any doubts or feel unsure what to do, I recommend to stick with Mike Sandlin's original design. If on the other hand you want are already building according to the BUG4 plans and want to know "what happens if I just..." or "what is this going to work like" then you are welcome here.

There is no way around the requirement to fully understand the original drawings. I'll help out with as much as I can, but please, Take Care.

File node-i06.html This is still under construction, but shows that it can be done, you can design your own plane and test fly it if you really want :-)

For the flight dynamics model, I have choosen to modify the LaRC-Sim code that is provided with the FlightGear package. This code is quite old, but from my University background I have easy access to it because it is written in regular "C" in the fashion that I have once learned to understand. Also, my old slow computer can translate this a lot faster than "C++".


File node-i07.html This is an easy to make, realistic enough cockpit for test flying my BUG2 flight dynamics model. The pedals and stick are connected to potentiometers that feed into a regular PC soundcard analog joystick adapter.
