Stock Patterns

These stock full-size hot air balloon patterns are ready to be delivered to you in electronic format.

Designed in 3D CAD, they have perfectly designed lofting, virtually eliminating unsightly vertical wrinkling inherent when using flat patterns.

Most patterns use the BARD profile.

About the BARD profile:

Compared to a natural shape balloon (aka 1962 Smalley profile), the BARD profile is optimised for fuel efficiency and easy flying in level flight (with a flatter top) and the mouth should remain tight and open in faster descents - since the profile is very slightly elongated and has straight sides in the bottom 1/3 of the balloon.

% loft is the maximum “puff out” between the load tapes on a vertical gore (refered to as “loft” – but also called bulbousness). The percentage is in relation to the diameter of the balloon at the equator. The lofting on all patterns tapers to zero loft at the mouth and at the parachute (for a good seal).

Patterns feature a first panel row of nomex.

Patterns are meant to be printed full-size on 60″ wide paper. Most sign shops can do this.

Patterns include:

  • Full size PDF files for each panel of the balloon including seam allowances:
  • Side view diagram (in the patterns section below)
  • Layout view of all the panels, load tape locations, etc. This can also be used as a coloring sheet:

Overview page with measurements for all parts such as red line, crown line, parachute confluence lines, parachute centering lines, envelope flying wires, as well as fabric yardage, including nomex.

Once you have decided on a color scheme, we can also 3D render your balloon:

What’s not included?

  • Step-by-step instructions are not included, but these are available elsewhere – either on the xlta.org website or inside the Balloon Builder’s Journal. Sewing a balloon is not difficult, it’s just alot of pieces, and alot of sewing!
  • Physical paper patterns. You have to get the digital files printed on paper yourself, or we can print them for an additional fee. We can also refer you to a US-based printing shop that can do this at a reasonable price, and they can ship worldwide.
  • Building materials. You have to source your own materials, although we do stock alot of hard to find materials such as nomex, webbing and red line (kevlar-core with polyester jacket).

There is a fee to be paid for permission to cut fabric for one (1) balloon from the patterns. Get in touch if you are interested in getting a copy!

Lastly, if any of these designs don’t quite fit the bill (if you wanted a different size, different # of gores, etc.), then we can definitely do a custom-design just for you. Most of the above patterns started their life as a custom pattern for others.
