Abstract [en]

This project will be a part of the LODESTAR experiment. LODESTAR is one of the experiments scheduled to fly on the REXUS/BEXUS 26 high altitude balloon flight. The primary objective of the experiment is to investigate the effects of cosmic radiation on CIGS solar cells. The objective of this project is to build a mechanical design that can fulfill all requirements set by the ESA user manual.

The mechanical design will first be drawn in mechanical CAD, where the drawing will be constructed from the ESA requirements. Later the design will be simulated in order to choose appropriate materials and a design that can withstand all simulations. Lastly the design will be built according to the drawings and tested according to the simulations.

The mechanical design withstood all the simulations and verification tests with no visual deformation, except for the simulation and verification of the drop test. Both the drop simulation and verification test resulted in deformation in one of the aluminium plates.

Since this mechanical design is constructed to be used only once, small deformations is within the margin of error. The deformation resulted by the simulation and verification of the drop test matched with a high precision. This is a good confirmation of the results of the drop test.

In conclusion, the executed tests gave very promising results. Therefor the design constructed fits all the requirements to travel with solar panels in stratospheric conditions.
