Aerodynamics and Fluid Mechanics
Aircraft and Helicopter Aerodynamics
Motivation and Objectives
The long-term research agenda is based on the continued
improvement of flow simulation and analysis capabilities
in the context of aircraft and helicopter performance
enhancement and drag reduction. Specific research
activities are dedicated to the reliable prediction of
flow separation onset and progression in the context of
vortex dominated flow and control of leading edge vortex
systems, development of a novel ROM framework for
aeroelastic analysis, helicopter drag reduction of rotor hub
and engine intake by shape optimization and flow control,
development of propeller performance and optimization
tool chain with respect to electrically driven flight vehicles
and fluid-structure interaction of membrane-type lifting
surfaces applied to wind turbine rotors.
Approach to Solution
The investigations have been performed using both wind
tunnel experiments and state-of-the art numerical simula-
tions. In-house codes are continously elaborated further
in the context of aeroelasticity analysis with respect to
time-accurate, fully-coupled simulations as well as the
application of novel neuro-fuzzy based reduced order
models. Commercial CFD codes are applied to flow
control problems and helicopter aerodynamics addressing
unsteady loads analysis and aeroacoustics.
