2Setting the new standard for on-shore application
100m - 3 MW
3The sizeWind turbine development
1981
2006
4The sizeFuture evolution trends
Offshore
Onshore
5Lifecycle
Use oriented design
Design
Manufacture
Installation
Operation
6Electrical capacity
Simultaneous full range operation at nominal power
Operating Voltage 90
Operating temperature 40 C
Reactive Power Supply 30
7Noise requirements
Low speed rotation to reduce noise inmission
100m
500m
At low level noise, the difference in rotational
speed pays a important role
8Logistics
Main figures for transport and installation
9Nacelle
Complete drive train, from rotor to HV

Approach on logistics challenge
12Supporting estructure
Low weight, direct rotor support since 1983
13The Blade
Specific design, 48 m length, 4 m largest chord
Excellent mass - stiffness ratio Only 9.8 tons
without use of carbon fiber Wind class IEC IIA
3 m Prebend Up to date aerodynamics New
profiles DU and experienced NACA Stronger and
more compact Superroot Root diameter 2.4m, 84 x
M36 Bolts
14The tower
The other side of the logistic challenge
The tower is built, without dynamic compromises,
in steel up to 80 m height with the transport
requirements of diameter smaller than 4.3
m. Hybrid towers are designed taller hub height
15General characteristics
