This work describes a computational method for
the treatment of solid fluid interaction (SOFIA)
for the assessment of the aerodynamic performance
of large span elastic wings by direct numerical
aeroelastic simulation. The fluid flow
is modeled by the Euler or by the Reynoldsaveraged
Navier-Stokes equations. The elastic
wing is modeled by a reduced structural model,
in this case a generalized Timoshenko-like beam
structure. Numerical results including detailed
comparison to measured data are shown for a
rectangular elastic wing specimen built within
the framework of the Collaborative Research
Centre SFB401 ”Modulation of Flow and Fluid-
Structure Interaction at Airplane Wings” of the
RWTH Aachen University of Technology.
