ESA PADRE Analysis Results

Summary - No Risk / PANEL3

Test case: Example SAMj Controlled 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 SAMj. Uncertainties in the initial state vector, atmosphere density, material properties, drag and heating coefficients are considered. A standard Monte-Carlo of between 1000 simulations has been executed.

Overview

• Number of samples where component demises: 1000 (100% of simulations)
• Number of samples with demise as an atomic object: 1000 (100% of demising samples)
• Number of samples with demise as a compound object: 0 (0% of demising samples)

The following distributions include results for all components that demise, including those that demise as atomic components, part of a compound fragment
