| Περίληψη: | Space is an unfriendly environment, where the materials of the space shuttle mission are
going to face significant challenging conditions. As a result, a big part of the ongoing research
concerns the materials’ degradation under space conditions. However, the ideal way to achieve
this is by sending an actual space shuttle into space, exposing the materials to the environment,
and inspecting them in a non-destructive way. Still, the economic aspect is an obstacle for
universities to apply their knowledge in this particular research field. On the other side, the
participation of universities in aerospace has grown dramatically over the last few years, with
more and more technical departments designing and sending nanosatellites into space. The aim
of the present thesis is the design a 3U CubeSat, which will include a deployable part for
conducting a material exposure experiment in space, recording the samples through a camera,
and transferring the results to Earth for further analysis. After completing the necessary
bibliographic review, in the first phase all the components of the satellite designed using CATIA
are presented in detail. Then and after the required specifications related to the geometry of the
satellite have been checked, the deployment part of the structure is kinematically analyzed in the
ADAMS software, where three different torsional springs are compared to be used for the
purposes of the experiment. Finally, the designed model is imported into ANSYS finite element
software in order to perform the necessary analyses and verify its structural integrity, examining
its behavior under quasi-static and dynamic loadings
