Coupers:

Have a questions:

One of our Cherokee 180's came back from the Prop Shop, (Great name for a
business),
today.  A modification had been made on the prop.  The trailing edge,
which had
been blunt, 90 degree angle on the ends, came back with a rounded end.

The reason for this, I am told, is to stop the end from reaching
supersonic.
This will cut down on drag that occurs just at the supersonic speed.

Now, give me some learning.  Does this work?  Would it work on a coupe?
What would be the benefits? Etc, Etc, Etc,.
I kind of like the ideal that my coupe may
have a supersonic ability.
