3-D Aerodynamic Design
The 3-D aerodynamic design is performed using NASA's
CCGEOM.  This code, coupled with Tecplot for viewing, provides
a very versatile tool, which can model virtually any
turbomachinery blade row.
Shown to the right is an
example of a centrifugal
compressor design completed
with CCGEOM.  The impeller
flow path is defined in the
meridional, R-Z plane.  The
blades are defined by
specifying the blade angle and
normal thickness distributions.
