This unique propeller postpones the phenomenon of cavitation due to its higher flexibility and torsion-bending coupling. The bonding of the composite propeller to the metal hub was particularly challenging because of the high cycle fatigue loads. The propeller was successfully tested in late 2017. The potential of this propeller lies in higher speeds and lower noise emission levels.
Chemical/corrosion resistanceComposite materials are resistant to a lot of chemical products such as acids, hydroxides, crude oil, etc. Corrosion resistance against salt and seawater is excellent.
