Balloon Builders Journal Compendium
The material on this page is current through June 2012.
NEW: The Balloon Builders Journal is now available for download at no cost. The download is in a ZIP file format of about 41.5 megabytes. To download the file
The Balloon Builders Journal was a series of 28, twelve-page newsletters published between 1993 and 1998. Each newsletter addressed a topic central to the construction of human-carrying balloons. Amateurs and hobbyists, not engineers, wrote these articles so the reader must assume all liability for use of this material.
Newsletters included letters from builders and personal reports on construction projects. Calculation tools, based on Microsoft Excel spreadsheets, allowed the builder to tailor balloon designs for specific mission goals.
The Balloon Builders Journal represents a non-profit effort to convey a great deal of balloon building information to interested readers. The Journal complex contains more than 374 pages of information.
The zip file is organized into two groups:
The Newsletters contain PDF copies of the original Balloon Builders Journals. Contained here are all 28 published issues. The feature article from the unpublished 29th issue is also included. While the original newsletters employed gray-tone photos the ZIP file contains color photos. The ZIP file also includes some additional photos related to the original articles.
The Extra Files contain a variety of additional material including various Excel spreadsheets, technical data and other unpublished articles and viewpoints. For example, two individual spreadsheets generate envelope lifting force and fabric cutting patterns, respectively. Build a microprocessor controlled envelope temperature gauge that generates audio reports using modified Morse code. Cost of the unit is about $15.
All reading material is accessible using the Adobe PDF reader. Microsoft Excel spreadsheets are provided for calculation tools. No internet browser is required to use the files. While the files were prepared using a PC a MAC can read all the files.
A brief index of each issue is listed below. A sample copy, Issue22.pdf, can be downloaded. It is approximately 905 Kbytes.
