Abstract
The de-icing system comprises a flexible bladder () filled with de-icing fluid, pressed by the centrifugal forces produced when the rotor tip () is rotating against the inner wall thereof to apply a pressure favoring the progressive and calibrated discharge of the fluid, in the absence of a pump and any other active means. For this, the bladder comprises a concavity () at the rear which is automatically enlarged under the effect of centrifugal forces during operation and discharges the fluid continuously from the bladder.
