Silent Power: Extremely silent rotor blades
With immediate effect, the Superwind 350 will be delivered
from the factory with superwind´s new Silent Power Blades.
The rotor blades have been optimized by superwind´s engineers
in extensive wind tunnel tests using sophisticated sound measurement
equipment and a special ambient sound elimination software. The result
is 10 dB (A) sound reduction which compared to the former blades is
experienced as just half the noise emission.
Even though the former blades have not been noisy at all, the gain in
comfort is amazing. The running Superwind is now hardly perceptible.
Neither by the own crew in the cockpit, nor by the neighbours at anchor
or in the marina.
The progress has been achieved by especially designed structures on
both sides of the airfoil, quite similar to a shark skin, which induce
micro turbulence for improved aerodynamic and acoustic performance.
The new superwind Silent Power Blades are fully
compatible to their predecessors which makes it easy to upgrade older
Superwinds to the state of the art.
