ROACH2 Preliminary Design Review (PDR)
ROACH2 Preliminary Design Review (PDR)
Auswahlworkshop in Bonn
The PDR (Preliminary Design Review) of our project ROACH2 took place on the 12th of February 2019 at the DLR in Oberpfaffenhofen as part of a Students Training Week.
ROACH2 is like its predecessor mission ROACH part of the REXUS/BEXUS program. A program sponsord by the German and Swedish space agencies (DLR and SNSA) to give students the opportunity to develop experiments launched onboard high altitude rockets or balloons.
ROACH2 is a rover which is supposed to drive a parcours in zero gravity only supported by electroadhesion on the inside of a REXUS rocket.
On the first day of Students Training Week the DLR and SNSA as well as ESA were introduced to us. We also got information on the REXUS Service System and on how to design our experiment for implementation. In the evening we had the chance to meet the other teams.
Throughout the week we had workshops about subjects like thermal design, software development, power systems, flight requirements, flight safety and system engineering as well as information about our next steps, as wel as the PDRs, 20 minute presentations followed by questions by the review board. They gave us some useful tips on things we need to improve.
The opportunity to question experts about our challenges that we encountered was really valuable to us. We were also informed on which rocket our experiment would be launched.
The last evening ended with a joint visit to the "Flugwerft Schleißheim".
BUBBLE 1 (BUoyancy Balloon Bus Lifted Experiments 1) is an high altitude balloon project.
We provide a stratospheric balloon and build the bus system with wich we can fly a payload up to 30 km hight. During the flight we will ensure communication with the groundstation and ensure recovery with an paracchute of the payload.
The project BUBBLE1 flyes two camera sensors from the IRS. The sensors collect data as a precurseir mission to the IRS project ESBO. Furthermore, this is the first flight of the bus system BUBBLE
SOURCE (Stuttgart Operated University Research Cubesat for Evaluation and Education) is a 3U CubeSat, to be launched in two years. Project phase A was completed in July of this year, we are now busy working on phase B of the project towards a Preliminary Design Review in January 2019.
Pump Application using Pulsed Electromagnets for Liquid reLocation(PAPELL) is an experiment to prove the basic functionality of pumps using ferrofluids in microgravitation. Ferrofluids are liquids that develop magnetic properties in magnetic fields and can thus be manipulated with magnets. The pump does not use moving mechanical parts, relying on the interaction between the ferrofluid and electromagnets. Careful activation and deactivation of the electromagnets can move ferrofluid drops through the experiment area. The experiment can show the possible future application of ferrofluid based pumps for future space projects.
ROACH (Robotic in-Orbit Analysis of Cover Hulls) researches the use of electrostatic adhesion for new locomotion methods in space. It will launch within the REXUS/BEXUS program aboard REXUS 24 in March 2018.
The project is inspired by the increasing threat to spacecraft posed by space debris and micro-meteorites. Hulls of spacecraft are additionally subject to fatigue, e. g. due to radiation. Both sources of damage can potentially destroy or impair the spacecraft. Based on this experiment, robots may enable autonomous maintenance by searching for damage and performing small repairs. The locomotion of such a rover on a spacecraft’s hull and its adhesion to the spacecraft is the primary challenge. The principle of electrostatic adhesion shall be used to achieve that.
KSat e. V. (small satellite student society at the University of Stuttgart) is a non-profit organization founded in the spring of 2014. The more than 60 members are students of all semesters, mostly enrolled in aerospace engineering. The association is open to students of all disciplines.
Our goal is to give our members the opportunity to realize their own spaceflight project during their time at university. Furthermore, we aim to pass on the knowledge and enthusiasm for space travel as part of our public relations work and to provide a communication platform between students, interested companies of the industry, research and the public.
KSat e. V. was founded by former SSETI students and therefore has a history of small satellite construction dating back to 2005. With MIRKA2-RX our members were able to accomplish their first successful mission 2 years after the foundation.
Beyond the engineering work, we are always prepared to enjoy a pleasant barbecue in summer as well as the obligatory Christmas party.
New members are always welcome!
