How E-Props Mastered Torsional Resonance with Ascalon Propeller

Support me on Patreon :   / letsgoaviate   I explain torsional resonance and why this is important when matching an engine and propeller. I also cover an analysis E-Props did on torsional vibration where they measured the torsional vibration level of their new Ascalon propeller as well as three other propellers. The Ascalon is E-Props' new propeller for direct drive engines like the Lycoming O-360, a propeller I've been waiting for in anticipation!
