AxCent combines the capabilities of four of the most widely-used
turbomachinery geometry codes, CCAD® and AXCAD®, as well as COMIG®
and TAXIG™. Pow-erful features are available for axial, mixed-flow
and radial geometries and these can be combined to design almost
any single or multistage turbomachine that can be conceived.
Blading features, from the simplest to the most complex, are
handled with ease. A partial list of capabilities includes
• Specication of 3D blades by stacking of 2D cross sections-
Standard parametric cross sections
are included for both axial compres-sors (DCA, MCA, NACA), and
tur-bines (Pritchard, improved Pritchard) as well as arbitrary
blade cross sec-tions. Spanwise graphical editing of cross sections
can be performed.
- Stacking is possible on the leading edge, CG and trailing
edge. The stacking curve can be radial or can be curved in either
the meridi-onal direction (bowing) or tangential direction (tilt).
The entire blade stack can be restaggered.
• Ruled element with option to have rulings independent from
leading and trailing edges
• Bowed or sculpted element with arbi-trary number of mid-span
sections
• Radial impellers• Flow cuts and radial trims• 2D impellers•
Swept leading and trailing edges• Multiple, offset and
independent
splitter blades• Fillets with constant or variable radius
and aspect ratio• Entire stage or multiple stages in
one le• Design with blade angle (β) or
wrap angle (θ)• Calculate and preserve throat• Calculate solids
passing• Quasi-3D ow analysis
In addition to geometry, AxCent includes several options for
real-time interactive flow analysis. Concepts NREC’s inviscid
streamline curvature solver has become the industry stan-dard for
centrifugal pumps and compressors. Axisymmetric throughflow using
industry standard loss and devia-tion models for compressors and
tur-bines is available, as is the ability to
substitute user-defined loss models and custom throughflow
solvers. A powerful, rapid 2D CFD-based blade-to-blade solver can
be used to quickly evaluate 2D cross sections.
Interface to Other ProgramsAxCent supports full interoperability
with Pushbutton CFD®, AXISTRESS™, and STRESSPREP™ (provides
interface for FEA analysis in ANSYS ®, COSMOS™, Abaqus®, and
NASTRAN ®). An interface to CTAADS™ for design of cooled turbine
blades is included. AxCent supports IGES files, plus output and
input for Concepts NREC 5-axis machining software MAX-5™, MAX-AB™
and MAX-SI™; seamless interface to Fluent, the most widely-used CFD
software; and interfaces to pass geometry to Numeca and CFX
TurboGrid. Full-featured optimi-zation and robust design
capabilities with iSIGHT software from Engineous Software, Inc. is
provided. Geometry transfer to and from major CAD sys-tems is
supported.
User-Friendly Features Step-by-step tutorials and extensive
context-sensitive help make AxCent easy to learn and use.

NEW PRODUCT!!
Mature and Robust Turbomachinery Geometry Generation CodeAxCent,
and its predecessors, has been continuously developed and improved
with a new version released annually since 1983. There are over 150
active AxCent licenses used worldwide making it the most mature and
robust turbomachinery geom-etry software on the market today. Our
improvement process is driven by our cus-tomers. Each year the most
requested fea-tures from our user base are incorporated into the
latest AxCent release.
Software SupportOur support network includes staff in North
America, Europe, China, Japan and Korea. Each of our support groups
includes experi-enced turbomachinery designers. Our soft-ware
maintenance plan, Agile Products Support, or APS, includes
traditional soft-ware upgrades and a help line. APS also includes
the unique feature of design reviews by our experienced staff of
turbomachinery engineers and complimen-tary attendance at our
world-renowned turbomachinery courses.
Direct Integration with Meanline ProgramsA designer can run
meanline programs, such as AXIAL, COMPAL and PUMPAL, side-by-side
with AxCent. AxCent can be started automatically from within AXIAL,
COMPAL or PUMPAL and will start with the relevant meanline geometry
already set. In addition, changes in AxCent that affect meanline
design can, at the user’s option, automatically cause the meanline
analysis to be rerun and performance maps regenerated.
