Severodvinsk launched - Video

As I understand it highly skewed propellers reduce cavitation along the end of the propeller blade, which makes me wonder if the Russians have developed something better to counteract that.

Or they have discovered it not as much of a problem.

Or they plan to change propellers once all the press is gone.

...Darn I guess my sig might need a remake... bah I like my version of the Severodvinsk better!

Screw design is VERY important when designing your propulsion train. With something as finely balanced and 'tuned' as your reactor plant and support equipment, you do not just change a screw out like you would on your personal watercraft.

This would be the final or very close to final design

Very odd then that they seem to have taken a step backwards.

The Akulas and Oscars have skewed prop blades, the Borei a pump jet, why on a Submarine started in 1993 they have opted for this type of prop?

They had Akulas at that time with skewed props...
