<strong>Software</strong> for Compumotor 6K Series ControllerGSC-14744-1This software controls a multi-axis motor system via a Compumotor 6K Series controller. Capable of runninga two-motor system with encoders, the software can be used to issue individual commands to a controller fortroubleshooting purposes, set position targets for the encoders, receive encoder feedback, turn over controlof a motor system to a joystick or other device, and record positional data from encoders to an external file.U.S. Government Purpose ReleaseSWIFT, v.400LEW-17635SWIFT is a multi-block computational fluid dynamics (CFD) analysis code for turbo-machinery. The software,which solves Navier-Stokes equations using explicit finite-difference techniques, can be used forlinear cascades, isolated blade rows, or multistage machines. Three differencing schemes are available:central differences, AUSM+, and H-CUSP. Three turbulence models are also available: Baldwin-Lomax,Cebeci-Smith, and Wilcox 2006 K-Omega.U.S. Release OnlySystem Identification Programs for AirCraft (SIDPAC)LAR-16100-1Written in MATLAB, SIDPAC is a collection of over 300 programs that perform a wide variety of tasks relatedto system identification applied to aircraft. SIDPAC includes tools for experiment design, data analysis,kinematic consistency checking, static and dynamic modeling, simulation, numerical integration and differentiation,smoothing, filtering, finite Fourier transformation, statistical modeling and evaluation, optimization,parameter estimation, model accuracy quantification, model validation, and more.General Public ReleaseSystematic Sensor Selection Strategy (S4) <strong>Software</strong>LEW-18815-1The Systematic Sensor Selection Strategy (S4) optimally selects a sensor suite from a larger pool ofcandidate sensors based on their performance in a diagnostic system. S4’s user-defined fault-diagnosticapproach considers conflicting objectives including cost, weight, and reliability.U.S. Release OnlyTCGRID v.400LEW-17635TCGRID is a three-dimensional grid-generation code for turbo-machinery blades. The software can generatesingle- or multi-block grids that are compatible with several computational fluid dynamics (CFD) analysiscodes, including SWIFT and ADPAC.U.S. Release OnlyTD2 Axial Turbine Design and Performance CodeLEW-11029TD2 performs a streamline analysis that can use meridional velocity gradients to control the radial distributionof work and flow for multistage, multishaft, cooled/uncooled axial-flow turbines. The effects ofstreamline slope and curvature are included in the radial equilibrium. Hub and tip radii are specified at inlet,at exit, and between each blade row, and velocity diagrams for each stage can be individually controlled.An internal loss correction determines blade-row total-pressure-loss coefficients along the streamlines.U.S. Release OnlyTempestTempest was created to provide Internet/Intranet connectivity to real-time embedded applications.U.S. Release OnlyLEW-172944.
