Airchair Technical Drawings

Last Update: June 24, 2017

Here are the technical drawings which describe the airchairs I have designed, built, and flown. They are released into the public domain and are free to anyone for any purpose. Each aircraft is described by a set of 70 to 90 drawings which is intended to describe the aircraft as it was flown.

1. Technical Drawings as Bitmaps, Viewable on the Web and Down loadable

For web viewing and downloading of drawings (in raster format, .gif bitmaps) go to my Online Photo Albums at:

These albums currently include the drawings for Goat4, Goat1, and Pig1, five albums per aircraft. Individual drawings can be downloaded directly from the Picassa Gallery. See below for downloadable files which contain all the drawings for a particular aircraft.

2. Technical Drawings in Download Files

These down loadable files are in vector CAD (Computer Assisted Design) formats, .dxf, .dwf, or .tcw (Turbocad, recent versions), except when in .gif which is raster (bitmap).

 Drawings in CAD formats (.dxf or .dwf) offer a much better view of small detail than the bitmaps (.gif) and should be preferred for any critical examination of the drawings. Also, a modern CAD program can use the .dxf files as a starting point (template) for making new or modified drawings, or as a source of components (the individual nuts and bolts can be taken out of the  original drawings and used elsewhere). Turbocad will open the .dxf files.

If no editing is intended, the .dwf drawings can be clearly examined or printed using available freeware. Autodesk Design Review 2011  is a free CAD viewer that works well with .dwf files. It will print  full scale to paper when  a full size template or part view is desired. 

 I may make changes to the drawings on occasion. Check the date on the viewable version of the drawing above to know if a drawing you have printed out is up to date. A later date will indicate that the drawing has been changed. Also a higher numbered zip file indicates a change.

Advisories:  I use only steel quicklinks. Aluminum quicklinks have recently become available, anodized in colored finishes. I have not used aluminum quicklinks because I suspect they would not be strong enough for my purposes.
