ROTOR BLADE DE-ICING
First Claim
1. A rotor blade (10) of a wind power plant comprising:
- a first and a second duct (16, 17) running inside the rotor blade (10) for conducting an airflow (21, 22),wherein a partition device (15) is provided which separates the ducts (16, 17) from one another, so that the first duct (16) is arranged on a first side of the partition device (15) at the pressure side (26) of the rotor blade (10), and the second duct (17) is arranged on a second side of the partition device (15) at the suction side (25) of the rotor blade (10).

Abstract
A rotor blade (10) of a wind power plant having a first and a second duct (16, 17) running inside the rotor blade (10) for conducting an air flow (21, 22) is provided. A method for de-icing a rotor blade (10) of a wind power plant is also provided. The rotor blade has a partition device (15) which separates the ducts (16, 17) from one another, such that the first duct (16) is arranged on a first side of the partition device (15) at the pressure side (26) of the rotor blade (10), and the second duct (17) is arranged on a second side of the partition device (15) at the suction side (25) of the rotor blade (10). In the method, the flow speed of the air flow provided in the first and second duct (16, 17) is predefined at least in portions of the rotor blade (10).

12. A method for de-icing a rotor blade (10) of a wind power plant, comprising the steps of:
-
providing a rotor blade (10) having a first and a second duct (16, 17) inside the rotor blade (10) for conducting an air flow (21, 22), wherein the air flow (21, 22) comprises a heated air flow (21), which is introduced into the first duct (16) and flows in a predeterminable flow guidance at least in sections in the direction from the rotor blade root (12) to the rotor blade tip (11), and de-icing at least one section (32, 32′
, 32″
, 32′
″
) of the rotor blade (10) with the air flow that flows along at least one part of an exterior wall (19) of the rotor blade (10),wherein the flow speed of the air flow (21, 22) in the at least one section (32-32′
″
) is or can be set. - View Dependent Claims (13, 14, 15, 16, 17, 18)
