Propeller optimisation

Propeller upgrade

The efficiency of a ship propeller grows with its diameter. However, propellers of inland ships have a rather small diameter because of limited available water depth. As a consequence the efficiency of is rather low as these propellers have to produce a relatively large thrust. Nowadays, naked propellers are seldom applied to inland ships as the power absorption is limited about 300 kW/m2 propeller disc area.
