Abstract

A six degree-of-freedom (6DOF) analysis of various conventional satellite bus configurations, and aeroelastic effects on the deployed solar panels during atmospheric reentry is presented. Accounting for demisability is an integral step of designing and manufacturing satellites and with disposable equipment on board, the emphasis on structural strength and robust thermal protection system (TPS) pales for a conventional satellite in comparison to reentry capsules, which are specifically designed to withstand the intense aerothermodynamic effects experienced during reentry. However, if the satellite contained sensitive or critical systems/payloads on board, it may be essential to ascertain and quantify these environmental effects in order to ensure the spacecraft’s survivability. This research examines the terminal reentry characteristics of common satellite bus geometry and solar panel array, including aerodynamic and thermal loading, and the deceleration imparted on the satellite body. This includes an analysis of structural dynamics as the solar panel array experiences loading due to these environmental effects, with focus on characterizing bending stress, vibrational mode shapes, and flutter if applicable.
