Meet Patrick Hambloch, student engineer with the Krefeld Centre of Expertise for YES2.
What are you studying and what's your specialty?
I’m currently studying Electrical Engineering with a specialty in Communications at Niederrhein University of Applied Science in Krefeld, Germany.
How did you get involved in the YES project?
I heard about the YES2 project in the summer of 2006. One of my professors, Ferdi Hermanns, was in charge of the Krefeld Centre of Expertise and responsible for the tether test rig and the winding machine.
He spoke about YES2 in a lecture and told us that we could get an internship at Delta-Utec to work on the project. It sounded really interesting, so after I contacted Michiel Kruijff (the YES2 system engineer) and became part of the team shortly after.
My six month internship started in July 2006 and ended in December. After that I was employed by Delta-Utec until April 2007 to complete my tasks within the project.
What was your role in the project?
I was the “Harnessing System Engineer” for YES2. I was responsible for all the cabling and electrical connecting equipment for the satellite. I designed, fabricated and then tested nearly all the cabling, both data and electrical.
When I wasn’t busy with that, I also helped develop the YES2 system engineering database: ALBATRos. This is a tailor made piece of software that Fabio De Pascale designed and created.
What were you working on in the project?
My first task was to figure out which connectors and cables for YES2 had to be made out of special materials for them to work properly in space. These cables needed to be constructed specially in order to reach the correct standard and be qualified for use in orbit.
I then continued the design process for the rest of the Harness. Some information was already present in the database from previous work done, but that data had to be completed. All connectors then had to be checked to guarantee that the right signals were associated with the right pins.
At around that time, I helped Fabio to further develop ALBATRos. Among the new features was a function that could automatically produce a harness production document from the component information present in the database. Creating this document allowed me to increase the quality of the cables and connectors I was producing greatly. I was then able to test these cables in the clean rooms at ESTEC.
