The CompAero software system is a suite of 20 centrifugal and axial-flow compressor aerodynamic design and analysis programs for IBM compatible PCs and 32-bit Windows operating systems ('95, '98, 2000, XP). The available programs are:


COMPAERO: a menu program to control the system and navigate among the other programs.

SIZE: a centrifugal compressor stage preliminary aerodynamic design program.
CENCOM: an aerodynamic performance analysis for single-stage or multistage centrifugal compressors. Sample Results.
GASPATH: a general gas path (end-wall contours and blades) design program.
VLDESIGN: a vaneless diffuser detailed aerodynamic design and performance analysis program.
VDDESIGN: a vaned diffuser detailed aerodynamic design, performance analysis and blade-to-blade flow analysis program.
RCDESIGN: a crossover-bend and return channel detailed aerodynamic design, performance analysis and blade-to-blade
flow analysis program.
FLOW3D: a quasi-three-dimensional inviscid flow field analysis with surface boundary layer analyses.
B2B2D: a two-dimensional blade-to-blade potential flow analysis with surface boundary layer analysis.
TDB2B: a time-marching blade-to-blade flow analysis with surface boundary layer analysis.
RKMOD: an ideal/non-ideal fluid equation-of-state package for a variety of thermodynamic property calculations (this equation
of state is used by many of the other programs). Description
GASDATA: a gas property database maintenance program to support Program RKMOD and the other programs that use its equation of state (including a current database of over 100 compounds).
BEZIER: a program to generate the curves used by Program GASPATH to construct the end-wall contours and blades. It can
be accessed directly from Program GASPATH or run separately.
RIGPAC: (RadialImpellerGeometryPACkage): a general geometry package primarily for impellers, but suitable for other
vaned components also. It performs many operations and geometry calculations commonly used in centrifugal compressor design and implementation (e.g., scaling, tip trims, imposing new profiles for different capacities, etc.).
Conceptually similar toProgram GASPATH, except that it starts from known geometry. It is often used to introduce existing component designs into the design and analysis system to apply the other programs for troubleshooting or upgrade activity.
AXCOM: an aerodynamic performance analysis for single-stage or multistage axial-flow compressors. Sample Results
AXSTAGE: an axial-flow compressor stage design program.
AXDESIGN: a multistage axial-flow compressor design program.
EXHAUST: an exhaust diffuser aerodynamic performance analysis (including a scroll or collector).
VOLUTE: a detailed geometry design program for volute passage profiles suitable for centrifugal compressors and radial- inflow turbines. It designs passage profiles at specified circumferential stations using elliptical or rectangular cross- sections for either external or internal volutes.
BLADE: a blade-section geometry program for the various standard axial-flow compressor airfoils.
PTC10: correts centrifugal compressor test performance to design (field) operation per ASME PTC 10-1997.
The CompAero system contains extensive data import/export capabilities to interface the various programs with each other and with other software commonly used in turbomachinery aerodynamic design and analysis view details.
