Using the Software

Getting Started with TrueProp Software...

Some users need a little help getting started – and that’s OK! We are here to help you maximize your use of TrueProp!

This brief introduction helps new users understand how to navigate through the TrueProp interface. This includes opening propeller scan projects, reviewing the scan history, analyzing the various graphical views, and generating reports for customers.

This tutorial assumes you have already installed TrueProp Software and the associated drivers before continuing. We also recommend setting your Project and Archive file storage directories from the Tools | Options…. Administrator tab.

Run TrueProp and you will see the main screen, PROJECT page.

Open a scan from the Project Library.
Click the OPEN button on the left-hand toolbar.
The Project Library dialog appears. This contains all of your propeller inspection projects, you can sort the data by clicking the desired column header.

Select a file and click OPEN to load the project data.

NOTE: If you do not have any scans in your library, consider adding the sample scans from the Samples folder in your TrueProp directory.
Each project file contains information about the customer. It also include the basic information about the propeller.You can store multiple scans of the same propeller in each project.

You can store Left-hand and Right-hand propellers of the same diameter in each project.

Click SCAN from the upper-most navigation toolbar. You will see the SCAN page.

This page is used to pull data from a inspection device and record it to the computer.
On the left-hand toolbar, you will see the Scan History.

Your first scan will be A. The next scan will be B, followed by C, and so on.

You will only see Left-hand or Right-hand scans in your history. You can change which scans are loaded from the Rotation field on the PROJECT page.

Click CHECK from the upper-most navigation toolbar. You will see the CHECK page.

This page is used to apply the ISO-484 criteria to your scan. It provides several graphical views for visualizing the data.
Click the PITCH button from the left-hand toolbar. This toolbar contains the different graphical view options.

The PITCH view shows the measured section pitch values for each radius. The left side shows the average pitch for each blade and the average pitch for the wheel.

The values of each pitch bar is shown towards the bottom of the bargraphs. The reference target value and the tolerance is shown at the top of each bargraph.

Click the RADIUS LOCAL button from the left-hand toolbar.

The RADIUS LOCAL view shows the face-line for each blade. This visualizes the pitch in smaller segments, called local pitch values.

You can change the displayed radius using the right-hand toolbar.

Click the BLADE LOCAL button from the left-hand toolbar.
The BLADE LOCAL view shows the local pitch values for an entire blade.
You can change the displayed blade using the top, right-hand toolbar.
Note: In both the RADIUS LOCAL and BLADE LOCAL views, the number of segments is dictated by the ISO-484 standard and desired Class.
In this view, TE indicates the Trailing Edge, and LE indicates the Leading Edge.

Click the OUTLINE button from the left-hand toolbar.

The OUTLINE view shows the chord lengths, position of the leading edge (i.e. skew of the leading edge), and the rake position of the blade centerline (BCL).

There are “field goal” markers to indicate whether the values are acceptable. If the lines are outside the markers, the criteria fails and the blade number (i.e. [1,2,4]) that is failing the criteria will be indicated near the marker.
Click the PATH button from the left-hand toolbar.

The PATH view overlays all face-lines from each blade. This visualizes the angular sweep vs the drop.
The rake tolerance is noted here with “field goal” markers. You can change the displayed radius using the right-hand toolbar.

Click the REPORT button from the top navigation toolbar.

Reports are available for printing and saving in PDF format. They are document the condition of the current selected propeller scan.

The STATUS report is a short, 2 page document with graphics to illustrate compliance.

The FULL report includes the graphics as well as additional pages with numeric data.
