SingleZygger? Open Source Airplane
Introduction Karoliina Model 1 Aircraft has a temporary name SingleZygger?. Kate invented the name Zygger from Karoliina's talks about Stagger-Ez because the Stagger sounded funny to us. So she started calling my drawings as zygger-pictures. Anyhow this is the place I am putting all data for the conceptual design I am doing, including Rhino drawings and everything. Karoliina Model 1 (Single Zygger) is not actually a single engine airplane, it actually has three engines - sort of. It is a hybrid aircraft with a single gasoline engine and two additional electric motors. If you are a aeronautical engineer or a student or otherwise well informed about the topic and you think you could be able to contribute, feel free to join the project. The project is fully open source and all design, plans and everything are with GPL or LGPL -style (copyleft) license.
The concept The concept has been defined as a long endurance high efficiency single engine plane with two additional electric motors. The plane shall have long endurance and long range and shall meet FAR part 23 safety requirements for landing speed and stall/spin behavior. The MPG target is high, the plane should be comparable to Toyota Prius in efficiency (kilometers per liter). DISCLAIMER Everything needed to build a proof of concept plane will be available for free to everybody. There is absolutely no warranty of any kind, use anything from this project with your own risk only. Why to join? The motivation for joining the project may vary, but one possible motivator can be getting some fame. If you are a student looking for e.g. getting a job from this field, instead of empty CV, you have something to show, you have contributed to one of the first open source airplanes in the World. Currently I am aware only of two other open source airplane projects, so this one could be the third one. You have a chance to be a pioneer. Click the join button now and lets make this thing into the reality together. Tools Open source tools are preferred, but also commercial tools may be used. The following open source or otherwise free tools are defined as standard:
The following commercial tools are included in the standard tools to use for this project (these are relatively affordable tools)
Other tools: Expensive tools like MSES, Catia V5, Mathlab, Mathcad, Fluent, FEM-programs etc. can be used to contribute to the work, but the data has to be provided in addition to the original format, in a format which is readable with some of the abovementioned tools or in plain text, pdf, or html format. Quick guide to subversion In order to access the subversion repository, you have to install subversion client to your computer. The subversion is available for Linux, MacOSX and also Windows. It is easiest and most natural to use from Linux and Mac, but also Windows users can take benefits from the version control system. svn checkout creates a local copy of the latest version in the subversion repository for you. You can edit the files, add more files (by svn add) etc. and then finally commit back with svn commit (the data is sent to the version control repository and your local copy becomes the latest version there). If someone edited same files as you did, you have to resolve the merging by hand. Otherwise your files are merged to the changes of the others (which edited other files than you). In Linux and Mac, you can just use the command line to svn checkout a repository. Windows users can use e.g. this guide how to use the svn in Windows: http://nedbatchelder.com/text/quicksvn.html Quick guide to wiki If you have links, ideas, concepts, etc. feel free to add pages to the wiki.
