Technical Overview
Stratos II/II+
The Stratos II+ rocket is almost 7 meters long and has a diameter of 20 centimeters. From top to bottom the rocket is comprised out of: the capsule, fairing containing parachute, nitrous oxide tank, engine control unit and the engine module. At liftoff the rocket will have a mass of 185 kg and will accelerate from 0 to 100 km/h in less than 0.9 seconds.
Engine
The engine, dubbed DHX-200 Aurora, produces an peak thrust of 11 kN, enough to lift a small car. It runs on nitrous oxide as oxidizer and a mixture of sorbitol (coffee sweetener), paraffin (candle wax) and aluminium as fuel. The engine will run for a total of 23 seconds at an average thrust of 8 kN, delivering around 180 kNs of total impulse. A total of 85 kg of propellant is consumed during the launch.
The hybrid rocket engine has been ground tested fourteen times at the facilities of TNO Rijswijk in the Netherlands and DLR Trauen in Germany.
Structure
The rocket is 7 meters long and constructed primarily out of aluminium. To enable radio communication, the nosecone is made from fiberglass. It is divided into several subsections that can be put together for assembly and launch.

Recovery
Housed in the fairing and the lower third of the nosecone section, dubbed capsule, there is a dual parachute system, consisting of a small drogue to stabilize the rocket during the supersonic descent and a main parachute for the final 2-3 km of its trajectory.
