AG Turbo 2020 4.1.5
Optimization of Linear Simulation Techniques for the Aeroelastic Design of Coupled Turbine Blades
TurboVaLd (Validation of turbulence models using Laser diagnostics)
Within the DLR internal project TurboVaLd, complex flows with relevant effects for turbomachinery are investigated in depth using optical Laser diagnostics.
SAMURAI (Synergy of Advanced Measurement Techniques for Unsteady and High Reynolds Number Aerodynamic Investigations)
Within SAMURAI, amongst others, a large field dataset of the ground-based engine jet of the DLR research aircraft ATRA will be made available with various image-based experimental measurement systems. These are used to extent the aerodynamic, -elastic and -acoustic knowledge of these two complex flow systems and for the validation of accompanying advanced numerical simulations.
In the framework of the joint project R&E TURB (Robust and efficient turbines for turbofans, geared turbofans and next generation turboshaft engines) of the Aeronautics Research Program IV the Numerical Methods department is involved in the work package 3 (Next Step Calculation-/Optimization methods) with the development of the simulation system TRACE.
The DLR internal Project HEAT investigates the thermal budget of turbine blades.
The aim of the DLR-project OmniTurb is to be able to do “Design, optimization and measurement of a two stage high pressure turbine with combustion chamber simulator”.
The main subject of this project is to reduce the noise generated by the fan, the combustion chamber and the turbine in all phases of a flight (take-off, overflight, and landing).
The department Numerical Methods is involved in BMBF-funded project GASPI in the field of high-performance computing. The aim of the project is to develop a high-performance library for unilateral and asynchronous communication on the basis of the Fraunhofer PGAS API.
The target course of the program system Digital-X is the computer-based design of aircraft and the virtual flight testing of these systems. The long-term goal is the development of an integrated software platform for multidisciplinary analysis and optimization.
Why thermal power plants need to be more flexible: the background of the project „COOREFLEX-turbo“
The project „COOREFLEX-turbo“ is devoted to the development of appropriate methods to improve the thermal power plants with respect to the afforementioned goals.
National Aviation Research Project: HDV2015
As developing modern aviation engines becomes more and more challenging with respect to reliability, degree of efficiency and weight, highly developed design tools are needed. These are connected with the quality of the design in an elementary way. Especially the increasing exploration and exploitation of technical boundaries and detailed designs let the demands on numerical simulation rise considerably.
