DEBRISK

Multidisciplinary software for the complete modeling of atmospheric re-entry of spacecraft

CNES Project2008 - PresentJavaMulti-platform

Overview

DEBRISK is a 100% CNES tool provided to companies and operators in the aerospace sector. It's designed for rapid analysis of spacecraft fragment survivability during atmospheric re-entry, using an object-oriented approach with simplified shapes and thermal models.

DEBRISK is distributed free of charge by CNES to make this tool accessible to the space industry for determining spacecraft survivability and their risk to populations on the ground.

Development History

2008

Development started with research into efficient calculation methods for spacecraft re-entry into Earth's atmosphere.

2013

First prototype delivered, handling geometrically simple shapes with test cases for verification and validation.

Present

New calculation strategy implemented by R.Tech based on high-fidelity calculations (CFD, DSMC) to meet the needs of more complex shapes.
