SECTION 3:Using AeroFlowA. Primary InterfaceThe application link can be found in the start menu in All Programs\Aeroprobe\AeroFlow\.AeroFlow opens to the standard interface shown below. A new project is created each timeAeroFlow opens. This is shown at the top left of the interface as Untitled Project. You canuse projects to organize various sets of data or experiments. This interface will be theprincipal tool for evaluating and processing probe data.Figure 2: AeroFlow Primary Interface6 www.aeroprobe.com • AeroFlow 2 Manual

TreeThe tree structure on the left side of the screen shows Pressure Data Files that have beenloaded and Velocimetry Data Files that have been reduced from pressure data. These filesare organized by probe serial number. The root of the tree, at the very top, shows thecurrent project name. Clicking the project name will show a summary of all selected AVFfiles, this is explained in the Summary View section below.There are several actions available in the Tree Structure via Right-Click as shown in Figure3: Tree Structure.Open File Outside of AeroFlowOpens the selected file with the default associated program outside of AeroFlow.Useful for viewing files in other programs such as Microsoft Excel.Show File in Windows ExplorerOpens Windows Explorer and highlights the selected file. Useful for navigating to a filein Windows in order to manipulate it as needed.Average Selected Pressure Data FilesAvailable by right clicking the Pressure Data branch in the Tree Structure. This optionwill perform an ensemble average of the selected files in the tree. The use will beprompted to save the resulting file, and it will be loaded into AeroFlow automatically.Figure 3: Tree Structure Right Click Optionswww.aeroprobe.com • AeroFlow Manual 7

LogThe bottom portion of the screen, the log, shows feedback from processes withinAeroFlow. The user can right click the log and choose Save Log to capture the current log.Saving the log and emailing it to tech-support@aeroprobe.com, along with a description ofa problem, is an efficient means of reporting bugs.BodyThe main body of the interface changes dynamically based on what is selected in the tree.When a Pressure Data File is selected, several visualization tabs appear. These tabs allowthe user to inspect the pressure data prior to reduction.When a Probe Serial Number is selected, the body shows the Probe Calibrations dialog.Here the user can load and unload calibrations for all probes.When a Velocimetry Data File is selected, a different set of visualization tabs appear,similar to the Pressure Data File tabs. These tabs display reduced data such as thecomponents of the velocity, Mach, Cone, and Roll.B. AeroFlow GuideDesigned with usability in mind, when AeroFlow is started for the first time, the AeroFlowGuide appears and directs the user through the proper usage of AeroFlow.Figure 4: AeroFlow GuideC. Loading Data Files (AeroFlow Guide Step 1)Click the Load Data File(s) button to load data into to the current project. The user can loadADF or AVF files directly into AeroFlow. Other data formats will need to be converted usingthe ADF Creator. To select non-default file types, click the file type drop down and choosecustomer data file(s) (*.*). The ADF Creator will be started automatically when a nondefaultfile type is loaded. See Appendix C. ADF Creator for more information on SupportedFile Types and usage.8 www.aeroprobe.com • AeroFlow 2 Manual

Entire folders may be loaded by clicking the drop down arrow to the right of the Load DataFile(s) button. This is incredibly helpful when batch processing large amounts of data.Figure 5 shows an example of the folder loading functionality. The user is presented withthe choice of loading only certain file types from the folder selected, and the user can addadditional file types when necessary.Figure 5: AeroFlow File Types and Folder Load ScreenA warning will appear in the log when data files are loaded and no calibration files arefound for the probe associated with the data.Unloading Data FilesThe user can unload files by selecting them via checkbox, and then clicking Unload DataFile(s). ADFs and their associated AVFs are loaded and unloaded separately.www.aeroprobe.com • AeroFlow Manual 9

E. Data Reduction (AeroFlow Guide Steps 4 & 5)AeroFlow utilizes all loaded calibration files in parallel when it is performing data reduction.Because of this functionality, the more calibrations that are loaded for each probe, themore reference data that AeroFlow has at its disposal, and the higher the accuracy of thedata reduction.1. Select the data files to reduce by checking each one in the tree structure2. Click the Reduce Selected File(s) button3. The log and progress bar will indicate the progress of the reduction process4. Any errors or warnings will appear in the logFigure 6: Reduction Progress Barwww.aeroprobe.com • AeroFlow Manual 11

Data Cursor / DataTipsThe Data Cursor tool lets the user see more information about a point of data on the graph.By clicking a point on the graph a DataTip is created which shows the X and Y Axis data ofthe point.Holding Alt and clicking on a data point will create a new DataTip instead of moving the lastDataTip.Right clicking the graph will allow the user to modify DataTip Options and Delete allDataTipsFigure 9: DataTip OptionsLines On/OffThe Lines button will toggle the display of lines between sequential data points. There isalso an associated drop down option to increase the width of the lines drawn. This optionaffects data points as well.Points On/OffThe Points button will toggle the display of data points on the graph. This option is on bydefault. There is an associated drop down option to change the display style of data points.Undock GraphUndocking the graph allows it to use more screen real estate. This may help with viewinglarge amounts of data.H. Summary ViewA summary view of the velocimetric data can be accessed by clicking on the project title inthe tree structure. To filter what is displayed, use the tree structure and check only the AVFfiles you wish to have graphed, then click the project title to graph the summary view.Figure 10: Project Summary Example shows an example of the Project Summary View.www.aeroprobe.com • AeroFlow Manual 15

Figure 10: Project Summary ExampleBelow the graph is the selection and statistics table. The checkboxes on the left allow the user to toggle the display of the graphed datasets. In this example three different types of probes are displayed to show the flexibility of the software.16 www.aeroprobe.com • AeroFlow 2 Manual

I. File TypesAeroFlow handles a variety of file types by default, as shown in Figure 5. This menu isaccessible by clicking File > File Type Settings. Custom file types may be added by clickingAdd File Type. Custom file types will be sent to the ADF Creator for conversion to the ADFformat.SECTION 4:TroubleshootingA. Installation Troubleshooting1. Aeroprobe recommends that user uninstall all previous versions of AeroFlow priorto installing a new version. In some cases, users may be unable to run AeroFlow iftwo versions are installed.2. If AeroFlow was installed along with a previous version, the user may be unable touninstall either version. In this case the error “Error opening installation log file.Verify that the specified log file location exists and is writable” May appear.Restarting the computer will allow the user to uninstall normally, after which theymay install latest version.3. Error: Could not find version X of the MCR (Figure 11).If this error occurs, the MCR (MATLAB Compiler Runtime) will need to be manuallyinstalled. This installer can be found within the AeroFlow installation directory, inthe bin folder. This is located at C:\Program Files\Aeroprobe\AeroFlow\bin bydefault. In most cases the AeroFlow installer may also be run again to install theMCR.www.aeroprobe.com • AeroFlow Manual 17

Figure 11: MCR ErrorB. Operational TroubleshootingKnown Issues:1. When AeroFlow is installed on one user profile, then launched from a different userprofile an error may occur. Currently the only work around is to use the software onthe same user profile it was installed on.2. Windows XP 64-bit does not properly run AeroFlow 2. No current work around forthis Operating System.SECTION 5:Meta DataA. Change Log1.

Appendix C. ADF CreatorFile FormatsThe ADF Creator can accept a variety of file formats. A non-exhaustive list includes:Excel files with a single sheet (XLS, XLSX, XLSM, etc.). Multiple sheets are not currentlysupported, even if they are blank.Text (.txt, .rpf, .csv, etc.)XML, ODS, DAQ, CDF, and many more.AeroFlow can also be modified to support custom file types for a small fee. Contactsales@aeroprobe.com for more information.Pressure Units Supported Pa (Pascal)Torr (torr)psi (Pound force per square inch)inH20 (Inches of Water)atm (Atmosphere)Pressure Units ConvertedThese units used in previous Aeroprobe software are converted according to the table below.Previous Unitpsf (Pound force per square foot)kPa (kilopascal)Converted to in AeroFlowpsi (Pound force per square inch)Pa (Pascal)Assumptions The ADF Creator and AeroFlow assume that the Reference Temperature is the TotalTemperature.All pressure units are assumed to be the same. For example, the port pressures andreference pressure are assumed to be in the same units.www.aeroprobe.com • AeroFlow Manual 23

Appendix D. Error CodesThe table below shows error codes that may appear in AVF files when a data point doesnot process correctly. The first digit indicates whether the point processed successfully (2)or encountered an error (3). These codes are set up in such a way that they can bedisplayed simultaneously. For example, error code 310101 indicates that three errorsoccurred: 300001, 300100, and 310000.Error Code Definition200000 No errors occurred for this data point300000 A general error occurred, typically an unrealistic calculated value300001 The closest calibration Mach Number is 50% more or less than the calculated value300010 The Static Pressure (Ps) is less than zero (1)300100 The Static Pressure (Ps) is greater than the Total Pressure (Pt) (1)301000 The Total Pressure (Pt) is less than zero (1)310000 The calculated cone angle is outside the calibration range1) In these cases the Total Pressure (Pt) and Static Pressure (Ps) will be set to the ReferencePressure (Pref).Appendix E.
