Meet Igor Sheynikov, student with the Samara State Aerospace University Centre of Expertise for YES2.
What are you studying and what's your specialty?
I was studying at Samara State University (SSAU) in the mechanical engineering/mathematics faculty. My specialty was Computer Security, with a secondary specialty in translation of English language in IT. I graduated in February 2007 with top marks.
This year I‘ve started as a postgraduate in Samara State Aerospace University. I’m studying complex safety of tether satellite systems.
How did you get involved in the YES project?
As a student, I had worked at SSAU in the Flight Dynamics department. I went to the second Summer Aerospace School and found it very interesting. This was the time in my studies when I first met Michiel Kruijff from Delta-Utec (YES2 lead engineer).
Shortly after, I joined the YES2 project under the guidance of Professor Ishkov. I helped a colleague, Sergey Naumov, continue his work on the project. In June 2005, I was invited by Delta-Utec to take part in carrying out some experiments and to continue my work in the YES2 team.
What was your role in the project?
I was involved with tether dynamics modelling and conducting experiments on the tether. I also had a role in the design and creation of the on-board software. It was exciting. We carried out some experiments and got very interesting results. Most of them concerned tether properties and qualities. Erik van der Heide (Delta Utec project manager for YES2) showed us his ripstitching ideas for the tether. Ripstitching is designed to dampen sudden tensions in the tether and prevent the tether snapping unexpectedly. We conducted some really interesting experiments on the ripstitching using the Zero-G Drop Tower at ESTEC.
What were you working on in the project?
There were several areas that I looked at while on YES2 and a lot of them had something to do with mission safety or contingency planning. Generally speaking, these areas were:
- Satellite tether systems dynamics
- Computer models of a possible tether jam during deployment and the resulting dynamics
- The potential implications of such dynamics for the safety of the Foton-M3 spacecraft
A small team of us also designed and created the on-board software for YES2 in Samara. We got to use the QNX operating system to design the software, which was great to use and really interesting. It took about three months and it was useful experience in terms of both teamwork and learning management skills.
