Trajectories of Rubber Balloons used in Balloon Releases: Theory and Application

TL;DR

This paper presents a comprehensive theoretical model and analysis of helium-filled rubber balloon trajectories used in releases, revealing their flight dynamics, potential range, and effects of weather conditions.

Contribution

It provides the first detailed physical modeling and real-world data analysis of balloon trajectories, filling a gap in atmospheric science literature.

Findings

Balloons can reach altitudes above 10 km.

Under optimal conditions, balloons can stay airborne over 24 hours.

Weather significantly reduces flight duration to 2-5 hours.

Abstract

Balloon releases are one of the main attractions of many fairs. Helium filled rubber balloons are released to carry postcards over preferably long distances. Although such balloons have been considered in atmospheric sciences and air safety analysis, there is only scarce literature available on the subject. This work intends to close this gap by providing a comprehensive theoretical overview and a thorough analysis of real-life data. All relevant physical properties of a rubber balloon are carefully modelled and supplemented by weather observations to form a self-contained trajectory simulation tool. The analysis of diverse balloon releases provided detailed insight into the flight dynamics and potential optimisations. Helium balloons are found to reach routinely altitudes above 10 km. Under optimal conditions, they could stay more than 24 hours airborne while reaching flight distances close to 3000 km. However, external weather effects reduce the typical lifetime to 2-5 hours.
