The Stratos III and IV missions of Delft Aerospace Rocket Engineering (DARE) are sounding rockets that aimed to reach altitudes between 60-100 km altitude. In order to recover the payload sections of the Stratos III and IV rockets, a two-stage recovery system was designed, containing a drogue parachute to stabilise and decelerate the vehicle. The d...
Retrieval systems are a vital part of sounding rocket missions. Even if the mission is completely successful, the failure in the retrieval subsystem can lead to the payload not being found back and thus a mission failure. This paper describes several retrieval strategies ranging from simple systems to highly complicated highly reliable systems. Sev...
The primary objective of the Supersonic Parachute Experiment Aboard REXUS (SPEAR) was to fly and collect in-flight data of a Hemisflo ribbon parachute at supersonic conditions. In November 2022, the SPEAR vehicle was successfully launched on top of the REXUS 28 sounding rocket from Esrange in Sweden. Shortly after the REXUS 28 apogee at 96 km, the...
Parachute testing is available in numerous shapes and forms, with each method being suitable for different applications. This paper aims to provide an overview of the various testing methods and to discuss the advantages and disadvantages they bring. The paper first identifies the relevant parameters for parachute tests and matches these to the var...

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...
