The department “Aeroelastic Experiments” is committed to the planning, realization and analysis of challenging experiments in wind tunnels.
We investigate physical phenomena regarding aeroelasticity and unsteady aerodynamics on transport aircraft, turbo machines, UCAV configurations, helicopters, rockets and large buildings like bridges or wind turbines. The compiled results lead us to physically reasonable indication of the problem-modeling of the observed phenomena and provide validation data for state-of-the-art numerical simulation.
Derived from the challenges to future transport needs we improve the physical understanding of flow phenomena and by this enable new technologies to the industrial application.
In our experiments complex wind-tunnel models with time-resolved measurement techniques for pressure, force, acceleration, motion and deformation are applied. We operate a facility for data acquisition and test control with 1000 A/C channels and time-synchronized sampling even over large distances. The department has several different test set-ups for aeroelastic experiments at airspeeds up to the transonic regime available. The set-ups are designed for investigating flutter, forced excitation and forced response of 2d and 3d wing-models and rotating and non-rotating turbine stages.
All competences are also offered to external partners in common projects or orders.
Together with different test set-ups and state of the art measuring techniques we can offer the complete service of aeroelastic wind-tunnel investigation from test design and preparation, manufacturing and equipment of complex models, performing tests and data evaluation. Experienced in the major European wind tunnels of DNW, ETW, ONERA.
