Particle Impact Risk and Vulnerability Assessment Tool PIRAT
The risk for operational satellites of being impacted by small
particles is increasing due to the rising amount of Space Debris in
Earth Orbits. Even collisions with small particles from sizes of one
millimeter upwards can have fatal consequences for satellites, if
such particles hit mission–critical equipment placed behind the
FRAUNHOFER INSTITUTE FOR HIGH-SPEED DYNAMICS,
spacecraft structure.

During the past 15 years, researchers at the Fraunhofer Institute
for High-Speed Dynamics, Ernst-Mach-Institut, EMI in Freiburg
have developed the computational methodology and software
tool PIRAT (Particle Impact Risk and Vulnerability Assessment
PIRAT WORKSHOP
Strasbourg
Tool). PIRAT computes the failure probability from hypervelocity
spacecraft component.

impacts. PIRAT allows to define and to explore easily protection
measures for particularly exposed components during early

spacecraft design stages. PIRAT quantifies the benefit gained
from application of specific protection measures. PIRAT was
introduced in 2014 in the European Space Agency’s (ESA’s)
Euroairport
Basel-Mulhouse
Basel
Concurrent Design Facility (CDF) as a tool to support ESA’s
engineers during Phase 0/A of spacecraft design. The software is
now available for licensing from EMI.
Workshop content
This workshop provides you with a comprehensive overview in
hypervelocity impact effects on spacecraft components and the
methods to derive spacecraft equipment survivability numbers based on it. Owing to 25 years of experimental analysis
of spacecraft component failures under hypervelocity impacts,
Fraunhofer EMI is offering you a unique experience in designing
spacecraft systems with high robustness against particle impacts.
Each participant at the workshop will receive a trial version of PIRAT and experience hands-on training by the developers of PIRAT.
