DARE DHX-400 ‘Nimbus’ Test

Updated 21/6/2017: At posting the team uploaded a video of their 4th test of the engine, which judging from the team’s reaction was a success!

Video Caption: The Stratos III propulsion team was facing some issues when the engine got a burn through after the first two tests. Check out this third engine test video and see for yourself with what engine we want to take back the altitude record!

Stratos III Engine Testing

As reported earlier, DARE have begun testing of their hybrid rocket engine for their Stratos III rocket.
The engine burns an 80/10/10 Sorbitol-Paraffin-Aluminium fuel mix with nitrous oxide as the oxidiser.

Here is the video of that test.
