DARE: Stratos II+ Data Analysis

The students of DARE have been running through the data produced by last year’s launch of Stratos II+. The rocket achieved a peak altitude of 21.5km, considerably short of the 50km as estimated by the team. This anomaly was soon found to be due to an inaccurate estimation of the drag in the simulations, as well as a vortex in the nitrous tank being created as the rocket rotated on its ascent which caused the engine to burn gaseous, not liquid Nitrous Oxide, resulting in underperformance on the engine.

The rocket achieved a peak altitude of 21.5km, considerably short of the 50km as estimated by the team, but in doing so breaking the European student altitude record. This anomaly was soon found to be due to an inaccurate estimation of the drag in the simulations, as well as a vortex in the nitrous tank being created as the rocket rotated on its ascent which caused the engine to burn gaseous, not liquid Nitrous Oxide, resulting in underperformance on the engine.
