Abstract

In order to de-ice a wind turbine rotor blade having inter-connected cavities, s heat transfer medium, pre-warmed if necessary, is circulated through the cavities.

A means for introducing a heat transfer medium into at least one cavity behind the leading edge of the blade is installed in the root end of the rotor blade, which is connected to a rotor hub.

There are flow channels which channel the heat transfer medium and connect neighbouring cavities in the end sections of the chambers at the rotor tip end.
