The development carried out with Helix has led to the creation of a completely new propeller that combines the characteristics of the already approved -NM- and -NL- propellers with the advantages of a new propeller, thanks to an innovative design and an anti-slip profile, called VH.
Starting from the heart of the propeller towards the external line, we see that the new propeller is characterized by a narrower and higher hub. This avoids the addition of the spacer thickness (M120) between propeller and transmission. The other lines that form the new VH profile from the center to the tips are a true combination of art, design and technology.
The new propellers, compared to the previous ones, have some important advantages:
– they are lighter, without affecting structural strength and safety;
– they allow fast acceleration and reduce the dynamic torque effects;
– they provide top performance for better static thrust;
– they give optimized fuel consumption at cruising speed, thanks to the new low resistance profile and the best angle of attack.
