The objective of this activity is to develop a software tool capable to accurately predict the fragmentation of a spacecraft duringdemise. The tools shall be developed taking into account the aerodynamics, thermal and structural phenomena contributing to such event.The main tasks of the activity are the following:- Review of the existing aero-thermo-dynamics/flight-mechanics coupled methodologies and tools, as well as flow/structure coupled methodologies and tools. Identify improvements and further development.- Develop a validated aerodynamic/flight-mechanic/thermal/structural analysis methodology and code, as part of the fragmentation analysis tools.- Develop an interface tool for re-defining and re-meshing the resulting geometry after each time step of the cycle analysis-Develop with a communication platform for the interconnection of the different modules above mentioned within a time simulation strategy.- Review of the existing structural analysis methods and tools employed currently as part of the fragmentation analysis tools. Identification of improvement and further development.- Development of a validated structural analysis methodology and tool, as part of and in support to the existing fragmentation analysis tools.- Integration of the structural analysis tool with the full analysis cycle.
