GRAB BAG 'O' WEB LINKS AND SUCH

I've created this "topic" so we can have a place to just point to interesting sites, of interest to LTA designers, but not as yet specifically linked to one aspect of our project.

If you've not seen the Festo "Air Ray" and "Aqua Ray" r/c craft, you gotta check 'em out.

Particularly the second film a this link:

Heres one to chew on  . Molded Depron light weight foam 1 mm thick  with gas bags inside . Think of the possibilities here  .

 A elipsoid  dome calculator for volume, and surface  areas  and ...?   http://www.monolithic.com/stories/advanced-dome-calculator

That's a good site. The reason I posted the formulas is I like to do my own spreadsheets. This gives me more flexibility in how I use this stuff.

Here is an interesting concept for an airship that never lands. http://www.lowtechmagazine.com/2009/02/gipsy-zeppelin-baseship.html#more

Here's a young Spanish man who made an eight-foot airship model in his family room. Nice neat video makes it look EZ.
   Which is is, now that I think of it.

Here is a Link to  discover how much your aluminum  (or other metals, even plastic )  frame members will weigh .
 I used it for  finding out how much  my  PHA  frame will  weigh and  It comes out to  right at  25 pounds less motor  !

New airships website, http://airshiphangar.com. It looks well designed. It has a directory for airships companies and organizations. It also has groups (I started one for us). I also put a link to it in the sidebar.

Cool video. Their model looks sooo sweet taking off.

UP! anyone?

From the above link....Note:   "Experimental"

Article says 1 helium tank per 8' balloon....(291 cubic feet each).... 283 balloons!!! 

This will be a great little motor and/or motor w/generator for a small airship platform!:  Propane / Hydrogen!!

I can see a nice home back up generator as well....

Hmmm.... wonder if they want to get rid of their balloons now....  guess there is only one way to find out....
