Determine Fan Blade length using touch circle

[[Ar...]]

I need to determine a blade tip length on 3 sections on  a fan blade. I am attempting to use touch circle on the section. Is this the correct method? The blade tips vary a lot from the model so I need a method based on a radius to determine actual blade length.

thanks.

Hello Art,

Have you already played with the different variants of the Profile Chord Line? (Section >>> I-Inspect >>> Airfoil >>> 1. create Camber line >>> 2. create Chord Line)

There are e.g. bitangential chord, axial chord or maximum chord, which may help to deliver the length measure of the tip you need. (For more details on these have a look in the direct help)

Does the suggestion get you where you want to go? - Jens
