Care should be taken when dismantling and
re-assembling the air turbine rotor, as, for maximum
aerodynamic efficiency, the blades feature fine trailing edges
which can cause injury if not handled with caution.
To assemble the wind turbine:
we recommend that you kneel and work on a firm surface, such
as the cockpit floor - this not only makes the operation easy, but
also makes it very unlikely you will drop any components
overboard!
slide the key on one blade root into the keyway on the next blade
continue in this way until you have assembled four blades
with the assembly resting on the floor with the gap uppermost,
position and slide the fifth blade into place
the air drive hub features concentrically arranged conical pins -
identify the matching conical recess in the turbine blade assembly
offer the turbine hub up to that side, aligning the pins with
the recesses
to complete the assembly, screw the clamping plate onto the
hub and tighten firmly
Spring pawls are fitted in the clamp plate to prevent vibration
from loosening it, and you will hear these clicking as
you tighten the clamp plate.
Use only firm hand pressure to tighten the clamp plate.
The spring pawls are factory set and secured with a thread-
locking compound. Do not attempt to adjust these in any way.
visually check that both hub and clamp plate are firmly seated
on the blade roots - there should be no gaps or movement
evident in the completed assembly
Before attaching the air drive to the yaw arm :
check that the upper tower clamp is securely closed and that
the locking pin is in place (see box right and pictures on Page 9)
check that the alternator yoke is locked centrally by tightening
the thumbscrew on the ‘c’ bracket
orientate the yaw arm so that you will be fitting the
turbine downwind, and ensure that it remains
downwind throughout the operation
The
upper tower clamp
holds
the machine in a vertical position
when operating in wind mode.
The clamp features a two stage
locking mechanism in order to
prevent accidental release when
the machine is running.
It is essential to ensure that this
clamp is secure. The clamp is
closed by swinging the hinged
retaining bar across the clamp
such that it engages in the gate
opposite the hinge.
The knurled thumb nut is then
tightened until the DuoGen’s
tower is gripped firmly by the
clamp.
Finally, the safety locking pin is
inserted which prevents the
thumb nut from becoming loose
due to vibration.
Note, when fitting the locking pin,
its lanyard should pass around
the tower as this acts as an
additional failsafe.
NB: If difficulty is experienced
when trying to close the clamp,
ensure that it is correctly aligned
and square to the tower tube.
