Gertler Series 58 Generator v0.6

Gertler Series 58 Generator v0.6

It’s been a one year since the first version of the Series 58 Generator and I am happy to release the second version of it today. Besides having a completely updated UI the new Version fixes some bugs and adds a couple new features.  You can now change the number of points used for the calculation, can change the separator characters for the clipboard format between TABs and semicolons.  As output there is now the CB – centre of Bouyancy and the polynomial coefficients a1 to a6. You can download it below.

Airshipworld Profile Generator Version 0.6
(AirshipworldProfileGenerator-v0.6.jar) 14,2Kb

You need Java 5 to run the generator either by double clicking the jar or run it from the command line via “java -jar AirshipworldProfileGenerator-v0.6.jar”

Gertler Series 58 Generator Preview – Now available for download

Gertler Series 58 Generator v0.5

Gertler Series 58 Generator v0.5

It’s taken a little longer than I had hoped but the first working version is DONE! Yes you read right I am proud to announce the first public version of the Gertler Series 58 Profile Generator. You can render different profiles based on the parameters and copy the points into your Clipboard. It’s completely working, requires you to have Java installed. Since I developed against Java 1.6 I would suggest that you also install it on your Computer you can give it a shot with earlier versions but I wont test it against those. If you test it and it works let me know.

So click on the link to download the Preview:
Airshipworld Profile Generator Version 0.5
(AirshipworldProfileGenerator-05.jar) 15,7KB

Once you have downloaded the jar and have installed Java properly you should be able to start the generator by simply double clicking on the Jar file. Or you open it via commandline by entering the command “java -jar AirshipworldProfileGenerator-05.jar”. Both should work but let me know if there are problems. Use the comments of this post to share your thoughts. Also let me know what features you are missing, any bugs you find, wishes you have. This application will be going open-source once we reach version 1.0 until then I will post updates here on the Blog so make sure to subscribe to get the latest updates.

The Email that started it.

So this Blog might have appeared a bit out of context for a few who I had not reached with my Email so this is the Email that started it:

Hello,
Many of us have started to collect information about designing Airships, some are even professionally designing them. Some hobbyist are building their own remote controlled airships, and some people are interested and just starting out gathering knowledge. Some might design airships by calculating on a sheet of paper or maybe excel, some might use specific tools. I believe that there are many many bits and pieces of knowledge spread around the community. The Building Industry has it’s tools and patterns on how to build cities, houses and other thing. The Computer Industry has patterns on how do structure and build software and also uses many different tools to make their work easier and simpler. Even the Conventional Aerospace industry I would assume has a large portfolio of patterns, tools and reference material to refer to.

The Airship industry might also have it but I don’t believe it is as sophisticated and readily available. From personal experience I have to say it’s rather hard to find the appropriate information or even the pointers to this information. To my information there is also no integrated development environment to develop an airship, that allows modeling, calculations and simulations in one software product. So my questions are:

Do you think we need a resource that collects the best practices and patterns probably pointing to specific books for further reference?

Do we need an Airship Development Software tool that helps us design airships in a computer aided design approach to have an integrated development environment. The question is not who will build it but who can see themself using it. And who would be willing to give the input in technical and business expertise regarding mathematical formulars, requirements aso.

I would love to start such a project and spearhead the Software Development since I am a Computer Scientist but i would like to know if you see a need for it and if you would be willing to contribute.
The Development model should be collaborative and the software or the resources and artifacts produced should be available for free as open source so that everyone can use them enhance them and modify them. Let me know what you think I could envision specialized versions for designing remote controlled airships and passenger airships.

And the feedback I got to this mail was generally Positive so this is the start. I will start to collect our collective knowledge when it comes to designing Airships. I will start open-source software projects, integrate others and introduce existing tools and illustrate how they can be used to design airships. I hope that the community chimes in. If you want to present how you design your airships, how you build your envelopes, which motors you use or just want to present your airship, let us know. Leave a comment and participate.

The Airshipworld Dev Blog is born.

Gertler Series 58 Generator V0.02

Yes you are reading correct this is the first post in the “Airshipworld Development Blog” the home of all software development efforts. Currently I am working on a Gertler Profile Generator based on the Series 58. The screen shot you see on the right is the current state as you can see it also draws a picture of something that looks like an airship. I am developing this software together with Johannes Eissing head organizer of the RC Airship Regattas he had the initial idea for the tool and supported me with his mathematical expertise as he developed the algorithms that drive the Gertler generator. The Profile Generator will be released as open-source once we have all the basic pieces in place. The Gertler Series 58 Profiles will be available as a free binary plugin for the Generator to protect the intellectual property which lies in the algorithms. The Generator will be the first in a series of tools and programs that will help others in designing and constructing their airships. I see the members of the RC Airship Regatta as the first users of these tools, followed by smaller companies that design remote controlled airships and once our toolbox has matured enough maybe even larger companies that design and build human piloted airships will find the toolbox as a worthy addition to their tool portfolio. Please leave comments and let me know what you expect. I will be posting updates on this Blog. I will talk about the development progress as well as other open-source and free tools. Spread the word!
