Nordex Advanced Anti-Icing System for N149/4.0-4.5Konrad Sachse
6th February 2019
Classification: Internal Purpose
Basic features:
Electrical resistance heaters
Heating aerodynamicallyrelevant surfaces (leading edge)
Low energy consumption –heating the surface rather thanblade structure
Fully operational during turbineoperation

New heating element
Cost ofEnergy
New benefits:
Reduced complexity of electrical system
No additional components in/on blade (except connections at blade root)
Reduced maintenance effort
Heating power/m² independent fromgeometry – optimized design for N149
Heating element is segmented
Manufacturing process much simpler
Classification: Internal Purpose
Tests with new heatingelement:
Since 2014: N117 in Finland
Since 2016: N131 in Finland
