Turboprop engine propeller efficiency data

TL;DR

Turboprop engine propeller efficiency data

Hello, I'm looking for data on turboprop aircraft engine propeller efficiencies.

I'm hoping for a table of available modern engines with a propeller efficiencies for comparison.

I've tried Googling but not much luck.

I can't even seem to find propeller efficiencies on the individual engine manufacturer websites.

Any pointers would be much appreciated.

A simple plot of efficiency is not possible because propeller efficiency is a function of RPM, airspeed, air density, and power. The propeller manufacturers have this information.
