In der Arbeitsgruppe Diagnostik hochenergetischer Strömungen befassen wir uns mit der Entwicklung und Anwendung von Messtechniken für hochenthalpe Strömungen. Dazu gehören hauptsächlich optische Messmethoden, wie optische Emissionsspektroskopie, Absorptionsspektroskopie, laserinduzierte Fluoreszenzmessungen und interferometrische Messungen. Darüberhinaus beschäftigen wir uns mit inversen Problemen, beispielsweise bei der Bestimmung von Wärmestromdichten auf Materialoberflächen aus eingebauten Temperatursensoren. Details zu den Arbeiten sind auf der entsprechenden Gruppenseite zu finden: Diagnostik hochenthalper Strömungen
High Enthalpy Flow Diagnostics:
I head the plasma wind tunnel laboratory at the Institute of Space Systems (IRS) at the
University of Stuttgart with 10 large-scale research facilities. Together with currently seven PhD
students and one Post-Doc, my High Enthalpy Flow Diagnostics Group (HEFDiG, www.hefdig.com) focuses
on the development and application of diagnostic methods for the characterization of high enthalpy
flows. I participated in four airborne entry observation campaigns for the
investigation of atmospheric entry physics in the past 10 years. With my team, I successfully
observed the re-entry of the European ISS-resupply spacecraft ATV-1 in 2008, participated in an
international team for the search of meteorite fragments (2008 TC3) in the Nubian desert in 2009,
and was Principle Investigator of a new instrument with which I successfully observed the re-entry
of the Japanese sample return capsule Hayabusa in 2010. I was Principal Investigator (PI) for seven
flight experiments for the quantification of atomic oxygen in the upper atmosphere in the years
2013-2020 on sounding rocket flights. I was selected as the first European science lead of a
re-entry flight observation mission ever, which involved
coordination of 33 international scientists for NASA and ESA managers for the observation of
the re-entry of the ATV-5 spacecraft in February 2015. I have been an invited member on the flight
observation missions of WT1190F and CYGNUS OA6. In 2016, I organized the International Workshop on
Radiation of High Temperature Gases (RHTG) of the European Space Agency. In May 2022 I was
participating in the airborne observation mission for the first detection of a meteor shower of the
tau-Herculids. I have published 79 journal articles, 6 articles in public journals and books and
more than 160 conference
contributions.
