- 3D inspection/analysis of
panelling, trim
state (static deformation & effector
settings), displacement modes,
pressure distribution & warping.
- Generation and editing of paneling
(including
sweep, taper, dihedral, thickness &
twist).
- Transparant Input&Output & ease
of use
- Aerodynamic geometry can be edited
in the app
- Structural data (geometry &
modeshapes) is
efficiently warped to the aerodynamic
geometry.
- Warpings can be stored for reuse,
accommodating
follow on stages of a design cycle ( Mach
number and/or frequency
changes).
- The solution matrices can be stored for
reuse accommodating follow on stages of
a design cycle ( mode
shape changes). Also it is made possible to
coarsen the paneling in one
button click to reduce computational
work.
- The calculated pressure distribution can
be
factored with a correction (Mach (Froude)
number, frequency and
position
dependent!) to accommodate transonic, boundary
layer and edge
effects.
- The calculations can
also be
performed in batch.
