What is DARE?
Founded in 2001
Independent agenda
Multiple projects
100+ members
Our Vision
Educating the next Generation • Small Rocket Project (SRP)
• Minors
• Bachelor and Masters Thesis
Unique hands-on experience
Large Projects
• Stratos I
• Stratos II
• Stratos II+
• Project Aether
• Stratos III

Our Projects Pillars of research – Structures Department
Lighter structures Better quality
(Optimization) Go higher
Our Projects Pillars of research – Structures Department
Lighter structures
Composites
Rocket body & parts
Connections & joints (welding)
High temperature parts
Metals
Design optimization
3D printed structures
Lighter & stronger metals
3D print
Design optimization
Lighter & stronger materials
Our Projects Pillars of research – Structures Department
Go higher
Multi-stage
Flight mechanics
Coupler mechanics
Simulations
Flight’s stability (Material optimization)
Fins
Canards
Active systems (+support)
Lower Drag Coefficient
Nosecone
Rocket body
Better overall recovery systems integration and
support
Our Projects Recovery Department
Designs and manufacture parachutes The drogue parachute
design : hemisflow ribbon parachute survive the high speeds while maintaining
stability. The main parachute
cross-shaped parachute. 15m2parachute -> largest parachute ever
developed by DARE. Carries out research on material and deployment systems
for the drogue and main parachute. Gas powered ejection and pyrobolts
Testing: mortar, explosive bolt and parachute designs Quite unique group in student rocketry societies.

Record breaking hybrid engines
• DHX-200 ‘Aurora’ – The propulsion system of the Stratos II+ rocket
Stratos III
• Launch before the spring of 2018
• Break the European student altitude record for
rocketry

Preparing for the future
• To go higher, more fuel and oxidizer is needed
• Structural weight needs to be decreased
• A new propulsion system in DARE’s portfolio
increases the overall capability of its rockets.
Cryogenic Propulsion team – Goals
• Develop a LOX-ethanol rocket motor • Learn LOX handling and safety
• Pressurized run tank
• Combustion chamber cooling
• Acquire data on cryogenic systems at ‘our scale’
• Quantify the costs and performance of such an
engine
• Create a flight version of the system

Main feed system structure holding all the valves LOX and ethanol flow,
Pressurization of the tanks
Left side is ethanol & right side is
lox
System is sized to fire for 18s, igniter burns for roughly 1s
Expected thrust without nozzle 0.5kN, with nozzle 2.5kN
DARE family
