KA-SPEED 3 TO 5 BLADES 39" - 150" Ø 

The KA-SPEED was developed by adding the advantages of skewed propellers to the traditional kaplan style.  It was conceived to be installed into our RICE SPEED NOZZLE* for best performances but it may also be installed into kort nozzles.

KA-SPEED offers you: 

Reduction on excitation level forces of the propeller.

Better distribution of blade stresses.

Smooth and silent operation (better than Kaplan propellers).

3, 4 or 5 blades from 39" to 150" diameter with any blade area ratio.

Speed Nozzle:

10% more free running.

10 times less drag.

8% more thrust at low speed.

3.6% or bollard pull.

8% minimum fuel saving when compared to Kort nozzle.

23% minimum fuel saving when compared to open propeller.

Smoother performance, vibration free operation.

Longer life nozzle.
