Rudder Propellers ► 130kW to 450kW ► New design ► Main or auxiliary propulsion ► Flexible mounting arrangements ► Class approved The new design of the Jastram rudder propellers RP230 and RP380 is based on 40 years of design and engineering experience. The proven high quality, dependability and robustness have been enhanced by the improvement of several technical details. The hydrodynamic shape was developed with the aid of CFD analysis. Our seasoned service engineers collaborated on the design process, ensuring cost-effective mounting and maintenance. In cooperation with the classification societies, these systems in varying configurations are approved for use in both inland waterway and marine vessels. The initial speeds of 1800 rpm and 2100 rpm mean that the rudder propellers can be used with all standard diesel engines. The optimum propeller diameters for these two rudder propeller types are 900mm for RP230 and 1100mm for RP380. Other customised propeller diameters are available. The following diagram and table show the performance ranges in relation to the propeller diameter and initial speed. Performance is restricted by the propeller surface load (kW/m2). Our engineers will be happy to help you select the best dimensions for your specific application and requirements.

Advantages of the propeller nozzle: ► Increased thrust ► Less noise and vibration ► Protects the propeller and objects in the water ► The nozzle is attached to the gear casing for easier servicing For propellers without a nozzle, an optional fin can be screwed on for protection against grounding. The cover plate prevents the...
