Sterna Propeller

3 Bladed Sterna Propeller

 

July 19, 2016   We Receive The 3 Bladed Sterna Propeller

We received one of the propellers that we will be testing on the R and D motor. We have had extensive consultation with Sterna propellers about the propeller that would work the best on the EMG-6 with the 20 hp electric motor. We have selected a propeller blade section that will optimize the performance at a very specific profile. Mainly the ability to operate in a cruise configuration at 45 mph.  We currently have 2 other propellers that are designed for the same motor that we will be testing as well. as we develop data once we begin the flight test program will use this page to accumulate information about this propeller. If the propeller works as expected we plan to offer this as one of the primary propellers for use on the EMG-6. We also plan to become an OEM dealer for the propeller and have them in stock or customers of the EMG-6. We are also working with Sterna for a propeller to be used on the Polini 250 motor as well.

I was first introduced to the Sterna propeller 2 years ago at Air Venture 2014. Sterna propellers are manufactured in China. Their footprint into the US is still somewhat small compared to other manufacturers but they are beginning to gain popularity. If you are at AirVenture, Sterna will have a booth set up and you can talk to them and see some of their other products in one of the big hangers.
