BLADES
The blades are made of composite material except for the erosion shield
(that is made of nickel) and some minor part.
The blades have a very long service life and are statically balanced as final
manufacturing process to achieve an individual interchangeability. In fact the
blade tip includes a pocket where masses are introduced to statically
balance the blade; the same occur in the root section.
The blades are composed of a constant chord profile with a parabolic tip.
The metallic pitch change arm lever is installed on the blade.
A lightning conductor jumper is attached to the top of each blade
attachment.
