ADIGMA - A European project on the development of adaptive higher order variational methods for aerospace applications


Computational Fluid Dynamics is a key enabler for meeting the strategic goals of future air transportation. However, the limitations of today’s numerical tools reduce the scope of innovation in aircraft development, keeping aircraft design at a conservative level. Within the 3rd Call of the 6th European Research Framework Programme, the strategic target research project ADIGMA has been initiated. The goal of ADIGMA is the development and utilization of innovative adaptive higher-order methods for the compressible flow equations enabling reliable, mesh independent numerical solutions for large-scale aerodynamic applications in aircraft design.

EU Project ATAAC


The ATAAC project aims at improvements to CFD methods for aerodynamic flows used in today's aeronautical industry. The accuracy of these is limited by insufficient capabilities of the turbulence modelling/simulation approaches available, especially at the high Reynolds numbers typical of real-life flows. As LES will not be affordable for such flows in the next 4 decades, ATAAC focusses on Differential Reynolds Stress Models (DRSMs), advanced Unsteady RANS models, Scale-Adaptive Simulation (SAS), Wall Modelled LES and different hybrid RANS-LES coupling schemes.

GOAHEAD - Generation of Advanced Helicopter Experimental Aerodynamic Database for CFD code validation


Today leading edge CFD software systems are available which are capable of predicting the viscous flow around complete helicopters. The greatest shortcoming for qualifying these methods as design tools in the industrial design process is the lack of detailed experimental validation data. This shortcoming is addressed by the project GOAHEAD which was initiated within the EU’s 6th Framework Programme. During the four years project the 15 partners will conduct a wind tunnel experiment with a model of a complete helicopter and will use the measured data to validate their CFD solvers.

IDIHOM - Industrialisation of High-Order Methods – A Top-Down Approach


The proposed IDIHOM project is motivated by the increasing demand of the European aerospace industries to advance their CFD-aided design procedure and analysis by using accurate and fast numerical methods, so-called high-order methods. They will be assessed and improved in a top-down approach by utilising industrially relevant complex test cases, so-called application challenges in the general area of turbulent steady and unsteady aerodynamic flows, covering external and internal aerodynamics as well as aeroelastic and aeroacoustic applications. Thus, the major aim is to support the European aeronautics industry with proven-track method(s) delivering an increased predictive accuracy for complex flows and (by same accuracy) an alleviation of computational costs which will secure their global leadership.

Leiser Flugverkehr II


Nach Abschluss der ersten Projektphase ist das Ziel der zweiten Projektphase, konkrete Lösungsvorschläge zu liefern, wie Lärm im Umfeld von Flughäfen realistisch gemindert werden kann. Dieses lässt sich auf vier Themenbereiche aufspalten: (1) Die Lärmminderung an der Quelle (insbesondere die Entwicklung leiserer Triebwerke) bietet langfristig das größte Potenzial zur Lärmminderung. (2) Lärmarme Flugverfahren sind dem gegenüber nicht so effizient, aber kurz- bis mittelfristig umsetzbar. (3) Verbesserte Werkzeuge zur Berechnung der Lärmbelastung im Umfeld von Flughäfen geben eine solide Grundlage für legislative und planerische Aufgaben und können außerdem zur Erarbeitung lärmarmer Flugverfahren herangezogen werden. (4) Untersuchungen zur Lärmwirkungsforschung sind notwendig um die Wirkung von Fluglärm auf den Menschen in belastbarer Weise zu quantifizieren.

MEPHISTO - Militärische Forschung zu Verfahren und Technologien für den Gesamtentwurf von UAVs


Mit dem Projekt Mephisto will das DLR in Kontinuität zu den DLR Vorgängerprojekten UCAV-2010 und FaUSST einen wesentlichen Beitrag leisten, die bereits erreichten Fähigkeiten der relevanten Disziplinen zum missionsspezifischen Entwurf und zur Auslegung sowie Bewertung von unbemannten militärischen Fluggeräten weiter zu entwickeln. Das Spektrum des konfigurativen Entwurfs und der Nachrechnung soll nicht nur hoch gepfeilte, agile, sondern auch Konfigurationen mit großer Flügelstreckung abdecken. Ziel dieses Vorgehens ist die Entwicklung einer Gesamtentwurfsfähigkeit die sämtliche Disziplinen des Fluggeräteentwurfs umfasst und ein hohes Maß an Flexibilität bezüglich der konfigurativen Gestaltung vorhält. Das Projekt Mephisto wird die Fähigkeitslücken zum UAV-Gesamtentwurf schließen. Hierzu wird eine Gesamtentwurfssoftware entwickelt, die Vorentwurfsverfahren und höherwertige Verfahren intelligent miteinander verknüpft. Durch einen solchen sogenannten „Multi-Fidelity“-Ansatz soll die Vorhersagefähigkeit der aerodynamischen Leistungsfähigkeit von UAVs verbessert werden, ins-besondere für den Bereich mittlerer bis hoher Anstellwinkel, in dem es gilt, hoch nichtlineare physikalische Effekte vorherzusagen.

SACOMAR - Technologies for Safe and Controlled Martian Entry


The success of future exploration missions to the surface of Mars strongly depends on an appropriate evaluation of thermal loads on the entry vehicle during atmospheric entry. Determination of heat fluxes during entry is one of the most challenging problems in vehicle design. A more accurate prediction could help to reduce design margin and increase the scientific pay load, but it requires improvements to the physical models which are currently used in numerical simulation tools. The improvement of experimental and numerical tools to study aerodynamic problems of Martian entry is one of the main objectives of the SACOMAR project which is part of the European Commission’s Seventh Framework Programme and is run on behalf of the commission by DLR.

SAMURAI


Uniquely in the world various and complementary non-intrusive and image based measurement techniques for mobile use in wind tunnels and free flight experiments have been developed in the institutes of AS and AT. Common practice was the selective application of these measurement techniques for the characterisation of flow conditions around wind tunnel models or their acoustical respectively elastical effects. The combined application of optical and acoustical measurement techniques enables the quantification of different fluid mechanically, aero-acoustically and -elastically relevant measurement categories like pressure, velocity vectors, density, model deformation and noise sources successively and parallel for a given wind tunnel model. By this as much as possible unsteady field data can be achieved, which cannot be determined otherwise.

SimBaCon


Vor ihrem Markteintritt müssen alle Arten von industriellen Produkten einen Prozess der Qualifikation oder Zulassung durch staatliche Stellen durchlaufen, um nachzuweisen, dass die geltenden Sicherheits- und Umweltvorschriften erfüllt werden. Dieser Nachweis ist für die Hersteller sehr zeit- und kostenintensiv. Man ist daher bestrebt, den Zulassungsprozess teilweise - oder sehr langfristig sogar fast gänzlich - im Rechner als „Simulation Based Certification“ durchzuführen. Die dazu notwendige Virtualisierung möglichst vieler Prozesse der Produktentwicklung und des Betriebs im Rechner ist derzeit zentraler Forschungsgegenstand in allen Bereichen des DLR. Um diese Aktivitäten zu bündeln, hat das DLR das Querschnittsprojekt „Simulation Based Certification“ (SimBaCon) gestartet.
