Rockets „powered“ by SILTEX

„For understanding we have to learn – for learning we have to share.“

Following this motto SILTEX is already for years sponsor to help for several universities and colleges – not at least  for Formula Student. But that is not the issue in this article today.

We are pleased with the Space Team Vienna University of Technology, which successfully launched two rockets at this year’s competition „C’Space“ of the French space agency CNES, and was able to complete the required services. We would like to congratulate the whole team, to obtain a coveted prizes.

Below we woul like of course the product of the Space Team not withheld.

„At the annual competition of the French space agency CNES for both experimental rockets launched rockets completed the required services and bestowed the Space Team one of the coveted prizes.

After a year of development work in cooperation with several institutes of the TU Vienna and thanks to the support of sponsors of the economy, a delegation of the TU Space teams in the last week of August to C’Space competition 2014 by Blomberg near Bordeaux. After a partially failed mission in the previous year, this year two now be further developed experimental rockets in their luggage.


Success at the second attempt

After intensive troubleshooting this time everything went according to plan: The advanced rocket STR-03A with the name Phoenix took off for its maiden flight and broke up after 18 seconds of flight time at the apex in nearly 3 kilometers high as expected, slowed down by parachute slide back to the earth. Thanks to the constantly for self-developed ground station transmitted telemetry data, the missile could be located and recovered rapidly 4 km away from the starting point.


Success with second stage

After this initial success, the 13 members of the Space Team is made on site from the second rocket brought prepare STR-04 Strive for launch. It serves as a concept study for the construction of a two-stage rocket and a scheduled flight to 40 km altitude. Due to the regulations for data acquisition and the second stage has not yet ignited during the first flight. Major challenge was the autonomous separation of the two stages at the right time by the on-board electronics, which succeeded the first time. The upper ensued alone its ballistic trajectory and parted a few seconds later even to eject her second parachute at the apex. Both stages of the rocket as planned slid to the ground and could be safely recovered.






A video of the rocket launche is to see in slow motion on YouTube.

With these successes, the students were paid in Space team for many months of preparatory work. Thanks to the knowledge and experience from previous years and the excellent teamwork completed two more complex systems reliably their first flights. Thus, the Vienna University of Technology Space Team was one of the coveted awards derFranzösischen space agency CNES decide for themselves.


Team of students from different disciplines

The existing since 2010 Space Team is a working group with main focus Aerospace Engineering at the Technical University of Vienna. Currently, about 40 students of various disciplines working on both experimental rockets as well as on other projects, including the development of sub-systems in satellites and lunar modules. The Space Team, offering its members the opportunity to gain first experiences working in the interdisciplinary field next to the study.

Finally, the entire team would like to thank all involved business sponsors, teachers and institutions of the TU : Only allow their support projects of this magnitude.
