For my thesis, I am responsible for the thermal control of the student nano-satellite project Delfi-n3Xt which is planned to be launched in October, 2012.My task is to assure all satellite components remain within their operating temperature ranges and are tested.
My second internship at Dutch Space was performed to do my literature research (course on TU Delft).This literature research focussed on deployable radiators for satellites. Deployable radiators are used for satellites with high-power density, these satellites often have problems dissipating all generated heat. The deployable radiator is a fairly new concept which is only used by a few satellite-manufacturers in the US.During my time at Dutch Space I reviewed the full design of the deployable radiator and collected literature on all its components and promising developments. Furthermore I provided an elaborate recommendation on whether and in what fashion the deployable radiator could become a promising recurrent product for Dutch Space.
For my internship I performed a detailed thermal analysis on the Hold-Down and Release Mechanism (HDRM) of solar panels for satellites. Due to increasingly efficient solar cells, the temperature of a stacked solar panel increases as well. To ensure a proper release of the solar panels, I performed the preparations for a thermal test on the HDRM. This test was needed to improve the thermal model of the solar panels and decrease the safety margin.As a second assignment I investigated the modelling methods of albedo radiation and Earthshine on spacecraft in low Earth orbits. I compared four modelling methods and gave my recommendations on which modelling technique to use in the future.
