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.
Access DEBRISKKey Features
Object-Oriented Approach
Simplified shapes and thermal models for rapid analysis
Parent/Child Relationships
Fragments can be grouped in hierarchical relationships
Flow Analysis
Calculates flow influence on debris characteristics at each timestep
Lethal Area Calculation
Determines impact zones and risks for surviving fragments
Supported Shapes
Boxes
Rectangular prism shapes for basic components
Cylinders
Cylindrical shapes for tanks and tubular components
Spheres
Spherical shapes for rounded components
User Interface
The software, developed in Java, complies with CNES RNC-xxx standards and uses external libraries to reduce development and maintenance costs (Patrius, JFreeChart, Commons Math).


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.
