Slides from TalksOshkosh 2008 - warning 36 megabyte file (there are lots of pictures.) These slides are from a talk given by Dan Nachbar at the EAA AirVenture Forum in Oshkosh on August 1, 2008 on building a hot air balloon. The first half of the talk gives an overview of the wide variety of homebuilt design options to consider. The second half gives a broad strokes picture of the steps involved in doing a first project. The file does not include two video clips that can be found at Mike Collier's website. We're fleshing out this this library. Below is one particularly useful and hard to find resource. Scientific/Technical Background InformationThe Scientific Ballooning Handbook is a very useful work published by NOAA/NCAR. While focused primarily on high altitude helium designs, this treasure trove contains some excellent, highly detailed technical analysis of the design of balloon envelopes. The average home-builder doesn't need to refer to this work. However, folks who really like to delve into the details of design and engineering will find lots of good stuff here. This books is a product of the US Government and as such is in the public domain.Each of these two PDF files is over a megabyte in size. So if you don't have a high-speed connection, click with care.
Part 1 - This part is of particular interest as it contains the a paper by Justing H. Smalley describing the calculations used in the well known "Smalley Spreadsheet"
