| DuoGen's air turbine is unique, consisting of five precision
injection-moulded blades. They are so consistent in weight
that they can be assembled in any order and always produce
a finely balanced turbine.The blades feature not only
twist and taper, but also a highly advanced low Re. aerofoil
section which continuously varies in camber from root
to tip to maximise aerodynamic efficiency. |
Clip-Together Blades |
| The blades themselves are uniquely designed to clip
together at their roots to form the completed rotor and
to readily slide apart to facilitate stowage. The precision
cast alloy hub fits through the centre of the blades which,
together with a clamping plate, form the complete turbine
assembly. The weatherised transmission, unique to DuoGen,
translates the drive from the turbine, through the telescopic
drive shaft to the alternator.
Once running, the DuoGen air mode performs powerfully,
delivering very similar outputs to the best conventional
machines of the same rotor size, but it does this in an
extremely quiet and non-threatening way. |
Alternator Remains At Deck Level |
As DuoGen's alternator is mounted at deck level, there
is minimal weight aloft, and DuoGen is the only machine
in its class to be protected by self-furling in storm
conditions.
The yaw radius of the machine is extremely compact which
simplifies mounting options and reduces the risk of accidental
contact with other equipment. |
Safe To Use Stop Handle |
| Stopping the DuoGen in air mode couldn't be easier or
safer. The yaw arm is provided with a handle placed well
clear of the spinning blades. Using this, the yaw arm
turns the turbine assembly out of the wind, and the blades
slow down until they stop. The blades can then be secured,
the yaw arm lowered, the air turbine removed and dismantled
for stowage. |

FACT: DuoGen's efficient,
slowspeed design produces impressive charging outputs
with a minimum of noise and vibration. |
| Note: All output figures have been obtained through
exhaustive field testing. They are representative of performance,
but due to the inherent difficulty of accurately measuring
dynamic systems, they should be regarded as approximations. |
