How to Calculate Burst Altitude for Balloons and HabHub Overview

What is the maximum burst altitude of your high altitude balloon? We explain how to use the HabHub burst calculator and the physics behind it.


Followup information from one of the original HabHub creators:

"Re: ascent rate. Here are the ascent rate profiles for 3 identical flights (same payload, balloon and fill) - as you can see they are pretty different. Identical Flights (https://www.flickr.com/photos/1682884...)

I think unless you can predict which profile your going to get your probably better off not over-complicating the modeling.

Re: scale height vs air density model - your correct it's similar. But the air density model value is empirically derived from balloon data and includes factors like the constraining effect of the latex envelope."
