ACD Aerodynamic Design of Multistage Axial-Flow CompressorsLEW-17448ACD is an analysis code used for the aerodynamic design of multistage axial-flow compressors. The technologyprovides velocity diagrams on the streamlines at the blade-row edges. Blade elements are definedby centerline curve and thickness distribution, and blade-element inlet and outlet angles are establishedthrough empirical incidence and deviation-angle adjustments to the velocity diagrams. Blade elements canbe stacked to provide the full blade design.U.S. Release OnlyACOD Multistage Axial-Flow Compressor Off-designLEW-17449A companion tool to Glenn Research Center’s ACD software (LEW-17448), ACOD is streamline analysis codefor predicting the off-design performance of multistage axial-flow compressors. Flow, blading, and loss aremodeled similarly to ACD.U.S. Release OnlyAdvanced Ducted Propfan Analysis Code (ADPAC)LEW-16768Note: <strong>Software</strong> Restricted by Export ControlDeveloped by the Allison Engine Company under contracts with Glenn Research Center, ADPAC solvestightly coupled internal/external flows through future-concept short-duct turbofan engines.U.S. Release OnlyAxial-Flow Turbine Off-Design (AXOD) PerformanceLEW-16323AXOD computes the flow and efficiency of multistage axial-flow turbines as functions of speed and pressureratio. The technology uses a span-line analysis with simple radial equilibrium. The loss model includesblade-row inlet losses, blade-row losses, and stage-test losses. Coefficients are selected to match theknown design-point performance, and the internal model provides the off-design performance.U.S. Release OnlyBLAYERLEW-P44BLAYER is a Fortran program used for calculating compressible laminar and turbulent boundary layers inarbitrary pressure gradients.U.S. Release OnlyBoundary-Layer Matrix Procedure Kinetic (BLIMPK) Modernization and UpgradeMSC-25641-1Written in Fortran, BLIMPK solves boundary-layer equations for arbitrary chemically reacting gases. <strong>NASA</strong>,the Department of Defense, and industry have all used the software in the design and evaluation of rocketnozzles and reentry spacecraft.U.S. Government Purpose ReleaseBroadband Fan Noise Prediction System (BFaNS)LEW-17307BFaNS computes the broadband noise generated by a turbofan engine’s fan stage. Noise sources caninclude turbulence impingement and boundary-layer turbulence convection.U.S. Release Only5. PropulsionCentrifugal Off-Design Performance (CCODP) CompressorLEW-17450CCODP is a one-dimensional off-design performance prediction code used for centrifugal compressors.Correlations account for the following types of loss: inlet guide vane, impeller incidence, shock, skin friction,blade loading, trailing edge, clearance, vaneless and vaned diffuser friction, recirculation, and disk friction.U.S. Release Only42<strong>NASA</strong> Technology Transfer Program <strong>Software</strong> <strong>Catalog</strong> 2014
