The Propeller Repair Software is designed to combine with the Propeller repair tools to give reasonable accuracy in the measuring of propellers from 9" to 20" Diameter. (Please note 9" is the minimum propeller diameter for the software to measure at 6" diameter. The 9" minimum for the software measuring does not prevent us from repairing smaller size propellers) Simple easy to use measuring software is designed for Windows based computers. Propeller measuring at your fingertips.

Below is a demo version of our PropKit1 software. This program is for demo purposes only and does not have true results. If you have a look at our how to Measure Propeller Pitch article it will give you the basics of propeller pitch measuring.

Step1

To use this program, select your propellers diameter from the combo box in step 1. If we are measuring a 3 blade 15 inch diameter propeller by selecting 15 our result would be 10 inches. As a general rule of thumb a 3 blade propeller is measured at two thirds of it's diameter and a four blade is measured at three quarters of it's diameter. Step 1 gives us an approximate diameter to set the pitch gauge at.

Step2

We can choose not to measure at the suggested measuring diameter in step 1 by selecting any diameter we wish. Click number 11 in step2. Select other numbers and watch the pitch holder move to suit. Now come back to 10 and move on to step3.

Step3

Once the required measuring diameter is selected and locked we move the two probes against the propeller blade . With a ruler measure from the back of the pitch holder to the ends of the probes. At step 3 enter the measurements of A and B probe. The program will calculate the difference. It does not matter if the propeller is left or right hand rotation as the program will change to suit. If we chose 47 in the left combo box and 17.5 in the right one the calculated results will be 19.337 inches of pitch.

Just a reminder, the information in this interaction is for demonstration purposes only, the results are intended not to be correct.

Lastly, in a more professional propeller repair environment we would perform multiple measurements across the face of the blades, with consideration of cup, rake and other variables.
