How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
The Supersonic Parachute Experiment Aboard REXUS (SPEAR) is an experiment flown on the REXUS28 sounding rocket as part of the REXUS/BEXUS program. The REXUS cycle lasts 1.5 years, giving the mission a strict timeline. The SPEAR mission aims to test the behaviour of the in-house developed Hemisflo ribbon drogue parachute at supersonic conditions. To...
Besides recovering a rocket for just the flight data, one can opt to recover the entire rocket, including the tank and engine. This can be done for public relation reasons, but also with full rocket reusability in mind. This article describes three concepts using parachutes to recover a sounding rocket in its entirety. As a reference design, a Stra...
Stratos III is a rocketry project led by students from Delft University of Technology. The goal of this project is to reclaim the European student altitude record for a sounding rocket, which is currently set at 32.3 km. The flight data of this rocket has to be retrieved to definitively prove the altitude at apogee. As not all data is sent down and...
In the summer of 2016 a group of students from Delft Aerospace Rocket Engineering (DARE) started a project to reclaim the European altitude record for amateur rocketry currently set at 32.3 km by HyEnD. This project was named Stratos III as a follow-up on Stratos II+. To recover the flight data, video footage, payload and valuable hardware, the nos...
