heal.abstract |
In this thesis, a tool capable of performing aeroelastic analysis of inflatable wings is
presented. In order to perform the aeroelastic analysis, the PUMA (Parallel solver,
for Unstructured grids, for Multi-blade row computations, including Adjoint) GPU-
enabled (Graphics Processing Unit) CFD (Computational Fluid Dynamics) solver
developed by the Parallel CFD & Optimization Unit (PCOpt/NTUA) is used for the
flow prediction and the aerodynamic load computation. For the structural analysis,
the commercial s/w MAPDL (Mechanical ANSYS Parametric Design Language by
ANSYS) is used, since it offers the capability to be executed in batch mode from a
script and can thus be integrated into an aeroelastic loop.
To perform an aeroelastic analysis with two different solvers, each one using a differ-
ent grid, Fluid Structure Interaction (FSI) tools are needed in order to interpolate
values between them. An interpolation tool based on finite element shape functions
is programmed in order to interpolate pressures from the CFD surface grid to the
CSM (Computational Solid Mechanics) grid and deformations from the CSM grid
to the CFD one. Also, an RBF-based (Radial Basis Function) grid displacement
tool is used for adapting and regenerating the volume CFD grid. Various interfacing
tools are also programmed to enable the fully automatization of the aeroelastic loop.
After programming the needed FSI tools to fully automatize the aeroelastic loop,
several aeroelastic analyses on inflatable wings are performed. Specifically, two
different geometries for the inflatable wing are designed and analysed. Also revisions
of each case are performed with different materials. Finally, analyses are performed
by using the inflatable wing including the tethers, which are used to support the
inflatable wing are examined in order to analyse effect on the aeroelastic problem.
Useful results for the aeroelastic behaviour of inflatable wings are thus extracted. |
