Another world's first takes first flight – the 11-bladed propeller!

MT-Propeller made another World's First to explore the possibilities in propeller technology.

On a PA31T1 equipped with the P&W PT6A-135A turbines, the World's first 11-bladed propeller took the sky with an impressive noise and sound signature. The very promising results in static thrust, 15% increase over the standard certified 5-bladed propeller, and the jet-noise signature showed another time what could be possible in the propeller developments. This propeller system combined with a low rpm power supply from a turbine or an electric engine opens new possibilities for performance, efficiency and noise.
