Fachgebiet
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:
Since 2008, I have been heading the plasma wind tunnel laboratory at Institute of Space Systems at the University of Stuttgart with 10 large-scale research facilities. My research group High Enthalpy Flow Diagnostics (www.hefdig.com) with five PhD students and one Post-doc focuses on the development and application of diagnostic methods for the characterisation of high enthalpy flows. With my team I successfully observed the re-entry of the European ISS-resupply spacecraft ATV-1 in 2008. I participated in an international team for the search of meteorite fragments (2008 TC3) in the Nubian Desert in 2009, and I was Principle Investigator of a new instrument with which we successfully observed the re-entry of the Japanese sample return capsule Hayabusa in 2010. Currently, I am leading the development of two sounding rocket flight experiments to analyse atomic oxygen in the upper atmosphere, with a first successful flight in June 2013. I was awarded science team lead of the observation campaign of the ATV-5 in 2015 (cancelled, see atv5.seti.org). In 2015 I was participating in the observation of WT1190F and my team observed the CYGNUS OA6 re-entry in June 2016. I have published 54 journal articles and participated in more than 130 conference papers.
