ESA PADRE Analysis Results


Test case: Example DRAMA Uncontrolled Component-Centric Vehicle Re-entry

Demonstration of the PADRE spacecraft assessment mode. This analysis simulated the destructive re-entry of a 1000kg component-centric vehicle, modelled as a relatively simple structore comprising approximately 40 components. Re-entry is predicted from a circular sun-synchronous orbit of 130km altitude using the DRAMA v3.0.4 version of SESAM. Uncertainties in the initial true anomaly, atmosphere density, material properties, drag and heating coefficients are considered. A standard Monte-Carlo of between 2000 and 5000 simulations has been executed.
