Model hot air balloons

Balloon Designer Version 2.1 (2003) is a design and mathematical modelling tool for model hot-air balloon enthusiasts, inspired by a balloon-obsessed friend in London and the Overflite website, which gives details of how to make the balloons (thanks to Tom from Overflite for his suggestions on the mathematical model).

As well as performance estimates and options for optimising the balloon, the software also features 3D modelling of the dynamics of the balloon surface to improve volume calculations and allow 3D graphic display of the balloon shape.


Research is planned on the feasibility of modelling the convection processes inside the balloon for more accurate estimates of temperature.
