It’s stored in a pressurised tank as shown in the illustration above. ARIS uses nitrous oxide, better known as laughing gas, as the oxidant. This will all be powered by a hybrid rocket engine, meaning that solid propellant will be combined with a liquid oxidiser. Hybrid rocket engines use solid propellant combined with a liquid oxidiser. More precisely, this year a 6.34-meter-long, 81 kilogram rocket called PICCARD with a diameter of 17.9 centimetres should reach its target at an altitude of 30,000 feet or 9144 metres with a maximum speed of 1.05 Mach in nine seconds.
It’s intended to deliver four kilogram payloads with a standard size of three cubesats up to 10,000 metres. Or to accelerate a rocket weighing 81 kilograms to over 8.5 g.
Furthermore, a lightweight design is to be used and thrust throttling integrated.įive kilonewtons of thrust is roughly equivalent to the weight force of half a ton – that’s how much thrust is needed to keep it in the air.The ignition phase before that adds up to four seconds. The burning time should be ten seconds.The thrust is said to have a peak power of 5000 newtons and should be able to take rockets to altitudes of up to 10,000 metres.A hybrid rocket engine, which functions reliably and is modular in design, is being developed.In addition to quick thinkers, ambitious goals are needed: Furthermore, he’s responsible for the explanations that will now follow. He can be seen in the top left of the first picture and has already worked on the RHEA and IRIDE projects as Project Manager and System Engineer. To ensure a perfect knowledge transfer of the previous year’s projects in all details, coaches and ARIS alumni are on hand.
However, the six new team members aren’t entirely on their own.
They take the first version of the engine, improve it and integrate it into the rocket.
