Turboprop engine propeller efficiency data

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. Hartzell has the following to say: Distribution of Hartzell Propeller Integration Manuals is limited and controlled. Please contact Hartzell OEM Sales for more information. http://hartzellprop.com/contact/.

See Hartzell's web page at https://hartzellprop.com/services/product-support-library/manuals/. Other propeller manufacturers for turbine engines include McCauley and MT-Propeller.

Hi there, I did a quick search and was able to find some information on turboprop engine propeller efficiencies. The best resource I found was a report published by the National Aeronautics and Space Administration (NASA) titled "Turboprop Propeller Performance Data for Preliminary Design." It includes a table of modern turboprop engines and their corresponding propeller efficiencies. You can access the report here: https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19960053467.pdf

Another helpful resource is the "Jane's All the World's Aircraft" book series, which includes data on various aircraft and their engines. You may be able to find a copy at a library or online.

I also suggest checking out the websites of specific engine manufacturers, as they may have technical documents or white papers that include information on propeller efficiencies.

I hope this helps in your search for data on turboprop engine propeller efficiencies. Good luck!
