Aircraft Aerodynamics

Institute of Aerodynamics und Gas Dynamics

The focus of the working group is the CFD-based analysis of complex flow phenomena and interactions on aircraft. This includes the study of massively detached flows as well as the control of separation and shock waves by passive and active control measures.

For the study of aerodynamic phenomena in commercial aircraft we use CFD methods based on RANS as well as hybrid RANS / LES methods. As flow solvers, we use the DLR codes TAU and FLOWer, which we develop further if necessary. The numerical studies include investigations of massively detached flows both in the low-speed and high-speed stall as well as the wake development up to the tail unit. The influence of a gusty inflow on the resulting transient loads and the aerodynamics of profiles, wings and airplanes is also investigated. The findings from these studies will be used to develop passive and active methods to control detachments and shock waves in transport aircraft configurations. With regard to novel, electrically operated aircraft, numerical investigations on the interactions between propellers and aerofoils are being carried out and work is being done on the favourable integration of distributed propulsion systems. The working group has a long tradition in the development of subsonic airfoils for aerofoils and rotors.
