The fifth wind tunnel campaign of DARE

On the 15th and 16th of March, the Parachute Research Group (PRG) of DARE performed its fifth wind tunnel test campaign. This wind tunnel campaign had two major test goals, which are the following: To accept the Stratos flight hardware To test reefing on cross parachutes The first goal was to determine if the new […]

Engine Control Unit and Umbilical

We are nearing the launch of Stratos III in the coming summer. This means it’s time to finish all hardware design so that we can focus on making the rocket behave as we want – the embedded system development can only progress when you have your hardware hooked up to each other. Without this interconnection, […]

Bleed Valve Control

Remember from an older blog post of mine where I went through the design process of an electrical-mechanical interface and ended with the futuristic-looking, 3D-printed prototype casing? In the meantime, we have been able to design, produce and test the printed circuit board (PCB) that goes on top of it: the bleed valve controller! After […]

CanSat launch day 2018

The first launch day of the year was reserved for the CanSat competition which was held on March 28th 2018. This was done in collaboration with NEMO, just like last year. During this day, a total of 10 high school teams launched their small satellites. The high school students had been working very hard on […]

Stratos III Recovery System

Touch down! After the ascent phase, the Stratos III nosecone will have to be recovered. The recovery is important as flight data and payloads are stored in the nosecone. Without a successful recovery, it could be difficult to validate the record. In some previous updates we have shown several parachutes and multiple parachute deployment device […]

The fourth wind tunnel campaign

On the 18th and 19th of December, the DARE recovery team performed the fourth wind tunnel campaign. The experiments, performed in the Open Jet Facility in Delft, were done to test several new parachute designs and to validate the Stratos III recovery system. Besides our own designs we were visited by Mads Stenfatt from Copenhagen […]

How to order a PCB

Recently we finished the design of the Recovery Printed Circuit Board and, after many reviews and small changes, it was finally ordered. At a Tuesday evening Electronics meeting we said “let’s order it tonight”, expecting it to take maybe an hour max. We still had to run some design rule checks, that’s when Altium checks […]

Electronics at DARE by Jun – Part II

Designing an electrical-mechanical interface In my previous blogpost I briefly touched upon the electronics that are in the works for our next flagship rocket Stratos III. Stratos III will feature multiple electronic systems made by the electronics department, but of course oftentimes multiple departments work together to design, realize and test a subsystem. So aside […]
