A safe descent: The Stratos III recovery system

When flying to high altitudes one needs a recovery system that can handle these altitudes and corresponding velocities. Not only does this system need to be able to withstand the high loads of the recovery, it also has to withstand the high dynamic pressures and temperatures.

DARE wind tunnel testing – The follow-up!

It has been a while, but on January 3rd, 2017 the recovery team, with help of other DARE members, found themselves back in the Open Jet Facility (OJF) to test several new parachutes again. In the week before the holiday, as well as on the holiday itself, people had worked hard to complete all the…
