DARE: DHX-400 Nimbus Test 20

The Nitrous oxide hybrid rocket engine will power the team’s Stratos IV rocket to over 100km, launching from South Africa in 2020.

DARE: Stratos IV Unveil

The 278 mm diameter, 8.286 m long nitrous oxide hybrid rocket is expected to fly to over 100 km in altitude when launched in the Summer of 2020.

Producing 26 kN of peak thrust and burning for 38 seconds, the team hope to not only beat the current European altitude record but also become the first European student team to reach space.

Check out the unveil below and click here for more info on the rocket and project.

Stratos IV Launch Delay

As per the below post, the team has decided to reschedule the launch to Summer 2020. Stratos IV is expected to reach the Karman line, they have some fierce competition launching this year so we will have to see how it pans out for that first place!

Stratos IV Design Presentation

I posted earlier that DARE unveiled their new Stratos IV rocket, well watch the official design presentation, what is new and what has changed from Stratos III? Watch below!

DARE Unveil Stratos IV

I am a little late to this, but the student team from TU Delft have recently unveiled their new Stratos IV rocket. Stratos III, which launched last year to break the European amateur and student altitude record was lost 20 seconds into flight due to a roll-pitch coupling. Stratos IV will carry on the legacy of its predecessor and will use essentially the same hybrid rocket motor, but with a titanium nozzle, a nitrous mono-propellant thruster roll control system, longer fins, and a more rigid fuselage. With all this taken into account, the rocket will reach 100 km in altitude and thus space. To do this the team plan to launch from Denel Overberg Test Range in South Africa, this is the same place that UKZN’s sounding rocket launched from.

Stratos IV stats
Length: 8.286 m
Diameter: 0.278 m
Dry mass: 101.6 kg
Propellant mass: 226.1 kg
Peak thrust: 26 kN
Burn time: 38 seconds
ISP: 180 seconds

DARE: Parachute Research Group News

As well as designing the recovery systems for the upcoming Stratos IV flight, the team will get a chance to test their systems in the REXUS/BEXUS program, first flight in 2020.

From the REXUS/BEXUS website,

The REXUS/BEXUS programme allows students from universities and higher education colleges across Europe to carry out scientific and technological experiments on research rockets and balloons. Each year, two rockets and two balloons are launched, carrying up to 20 experiments designed and built by student teams.
