8th PSP Course - Application of Pressure Sensitive Paint - Theory and Practice
February 18 - 22, 2019, Göttingen
For investigations of pressure distributions on wind tunnel model surfaces with high spatial resolution, new experimental techniques such as Pressure Sensitive Paint (PSP) are required. Using this non-intrusive optical pressure measurement technique, spatial structures and/or rapid temporal or spatial changes of aerodynamic phenomena (transition from laminar to turbulent flow, shocks on pitching airfoils in transonic flows, coherent structures etc.) can be investigated. Recently an increasing number of scientists and engineers has started to utilise the PSP technique to investigate pressure distributions in transonic, low speed, hypersonic and cryogenic wind tunnels, as well as in turbo machines. The PSP technique has also evolved from the measurement of steady state pressures to include both periodic and unsteady phenomena to study the instantaneous structure of pressure fields in various areas of fluid mechanics. This course, which is the eighth one on PSP organized by DLR Göttingen, Germany, will concentrate on both measurement techniques and aspects of the theory of PSP relevant to applications. In addition to lectures on the fundamental aspects of Pressure Sensitive Paint Systems, emphasis is placed on the presentation of practical and reliable solutions for problems faced during the implementation of the technique in wind tunnels and other test facilities. During practical sessions in the course, the participants will have the opportunity of carrying out experiments in small groups on PSP/TSP characterisation, coating technique, and the recording and evaluation of PSP/TSP data. Recent developments of the PSP/TSP technique will be discussed and demonstrated. In addition the application of Temperature Sensitive Paint (TSP), which is from the technical point of view very similar to PSP will be part of this course.

27th PIV Course - Application of Particle Image Velocimetry - Theory and Practice
March 18- 22, 2019, Göttingen
The main interest of today’s research in fluid mechanics is more and more directed to problems where unsteady and separated flows are predominant. For investigations of flow fields with pronounced spatial structures and/or rapid temporal or spatial changes (transition from laminar to turbulent flow, coherent structures, pitching airfoils in transonic flows with shocks, rotors, test facilities with short run time, etc.) optical experimental techniques, such as Particle Image Velocimetry (PIV) and Lagrangian Particle Tracking (LPT) are required which allow to capture the flow velocity of large flow fields instantaneously.

STAB-Preis für Forschung und Entwicklung auf dem Gebiet der Strömungsmechanik
Bewerbungsfrist: 31. Mai 2018
21. Februar 2018
Die Deutsche Strömungsmechanische Arbeitsgemeinschaft, STAB wurde auf Initiative der Deutschen Gesellschaft für Luft- und Raumfahrt (DGLR) - Lilienthal-Oberth, e.V. - 1979 von Strömungsforschern, Aerodynamikern und Luftfahrtingenieuren aus DLR, Hochschule und Industrie ins Leben gerufen. Sie entstand aus "dem gemeinschaftlichen Bestreben, die Strömungsforschung in Deutschland generell zu fördern und durch Konzentration auf ein wirtschaftlich und forschungspolitisch zukunftsträchtiges Teilgebiet zu vertiefen".

Microphone Arrays for Aeroacoustic Measurements
June 4 - 6, 2018, Göttingen
Aim of the MA|AM course is to improve the knowledge for the practical application of microphone array measurements in wind tunnels, including the post-processing and the interpretation of the achieved results. Test engineers can participate to obtain the necessary knowledge to improve the quality of aeroacoustic measurements with microphone arrays and prevent costly errors. Contractors and end-users of array measurement results will learn how to assess the potential of aeroacoustic wind tunnel measurements and how to interpret the achieved results appropriately.

Announcement of the 1st European Workshop on MDO for Industrial Applications in Aeronautics – Challenges and Expectations
24-25 October 2017 Hosted by DLR, Braunschweig, Germany
Multidisciplinary design optimization (MDO) based on high- and multi-fidelity methods have been intensively investigated during the last decades in academia and government research labs, and were shown to be promising tools for aircraft design. However, the perception exists that only limited transfer of formal MDO techniques into daily design work of aircraft manufacturers has been achieved until today. This European workshop is the first of a planned workshop series organized by DLR, IRT Saint Exupéry and ONERA. The ambition is to establish a European MDO community to enhance collaboration on the subject.
