Structural and Thermal Design and Analysis of an Earth Reentry CubeSat

摘要

This thesis is about the structural and thermal design and analysis of an Earth reentry CubeSat RSAT The objectives are to offer a design of CubeSat that fits the components required for the mission that can withstand the launch conditions and that can keep the satellite in acceptable temperatures in orbit and only part of it during the reentry while meeting the various requirements CATIA is used to design the satellite and the design is based on QARMAN another reentry CubeSat The structural analysis assesses whether the satellite can sustain the launch or not using different tests and comparing the results to the requirements The structural analysis is done with Ansys The thermal analysis starts by simulating the satellite in orbit with Analytical Graphics Inc Systems Tool Kit to obtain data such as the position of the Sun and of the Sun glint compared to the satellite These data are then computed to obtain the fluxes that the satellite will receive on each face in orbit The heat exchanges are then simulated with Ansys Transient Thermal by modeling the fluxes the radiations and the heat dissipations Cold and hot cases are simulated to cover the whole domain the satellite will experience The temperatures are then analyzed to conclude whether or not they are good for the mission
