The nacelle protects the alternator from external climatologically agents. The
nacelle is attached with four bolts; two of them are on upper part, one is on the
back with a clamp, and the last one goes in the flange on the lower frontal
section:
On the top of the nacelle there are two holes ready for two M-6 x 15 bolts with
their correspondent wide series M-6 washers and a grover washer, directly
bolted to the alternator bridge. The assembly order is: bolt, grover washer and
wide washer.
Next, the clamp bolt must be tightened at the back part of the nacelle.
Finally, on the lower front side, using the two flanges to anchor, we insert the
brass tube (108 mm long x 10 mm exterior diameter), one M-6 x 130 bolt, with
an M6 wide series washer on each side, on the inner side of the nacelle between
the two flange-forming flaps. Finally, secure using a washer and auto-blocking
nut.
Blades and frontal cone
The blades, made reinforced carbon fiber/glass make direct contact with the
wind. They are highly stressed. Their aerodynamics, specifically designed for
Bornay wind turbines, makes the alternator turn faster or slower depending on
wind speed.
Blade assembly is carried
out by securing them to
the hub, with the relief
logo towards the rear
part, i.e. facing the
alternator. The two
external bolts will be M-10
x 60, while the central
internal bolt - now
installed - is M-10. Once
installed, the blades must
be adjusted. Without using
any nuts or washers, the
aluminum hub
reinforcement layer is assembled, and this will give the assembled parts more
