ABSTRACT:
The invention describes a supercavitating propeller with adjustable cup, and a method to adjust the cup. The trailing edge of the propeller blade is characterised by a protuberance with a limited section compared to the blade's section at the conventional trailing edge. The protuberance height can be adjusted, hereby reducing the propeller blade's cup.
