Submarine blades are a sophisticated product optimized for low noise levels at specific speeds. Through the shaft and blades of the submarine boat, special channels can be passed for supplying fluid under pressure. By controlling the pressure, temperature and amount of the pumped liquid, you can change the noise trail (noise palette) of the submarine and make it difficult to identify. Another option for reducing the signature of submarines is the formation of a wide flat or figured wake. https://bretell.blogspot.com/
