Interesting propeller shape. Any idea?

688i propeller in RA

Hmm I think the unconventional shaped propeller is meant to optimize on speed but does it offer any other advantages?

I thought it was the Russian submarines which are fitted with propeller shaped to give them maximum speed(push power) while the US submarines are fitted with propeller shaped for optimum noise performance(least noise).

If this is the shape of a propeller for optimum speed how is the shape of the propeller designed for optimum(lowest) noise performance?

Is this propeller(as shown in the picture) realistic to be fitted in 688i class SSN?
