TECHNICAL ADVANTAGES

 

The technical advantages of Stormfågeln can be summarised as follows:

 

· No appendage drag

 - An integrated solution

· Good acceleration

 - Smooth transition through the planing threshold speed

· High manoeuvrability

 - High precision

 - Good reversing properties

· Ventilated propeller

 - Air and exhaust gases led down to the propellers

 - Lower torque, higher efficiency

· No transient speed

 - Constant speed even through the planing threshold

· Lower variation in blade pitch

 - Higher efficiency

· Optimal rate of revolution

 - Adjustable propellers

 - Low fuel consumption

· Higher propeller efficiency, 65-70%

· No need of gearbox or reverse gear

· Lower pulsations

 - More propeller blades, lower vibration and higher efficiency
