the Airpup kite balloon

Airpup in flight

This repository contains the 2D patterns for constructing Airpup as well as a corresponding 3D model. 2D patterns are made with QCAD, the 3D model was made in Audodesk's Fusion 360.

See more of my kite and balloon projects at headfullofair.com.

mounting rails

The folder /rails contains CAD files and STLs for end caps and two-part slide mount: The belly mount has a sliding rail system

the rails allow quick weight adjustment

envelope construction

The envelope is a 3-gore pattern seamed in a single run:

pattern fold

envelope volume and flat patterns

Airpup's envelope volume is roughly equivalent to a sphere whose radius is 1/3 the length of an inflated Airpup.

Airpup's flat envelope pattern is 1.147 times the length of an inflated Airpup.
