Abstract
Provide is a rotor blade for a wind turbine, including a hollow blade body with a root and a tip, wherein the blade body is split along a split plane into two body parts, one extending from the root to a first connection section and the other extending from a second connection section to the tip, wherein the first and the second connection sections are adapted to overlap each other in the connected position.
Claims15
A rotor blade for a wind turbine, comprising
- a hollow blade body with a root and a tip wherein the hollow blade body is split along a split plane into a first body part and a second body part, the first body part extending from the root to a first connection section and the second body part extending from a second connection section to the tip;
- wherein the first connection section and the second connection section are configured to overlap each other in a connected position;
- wherein the split plane is in an area where the rotor blade has a convex peripheral geometry and where the rotor blade has a single curved cross-section seen in a direction from the root to the tip;
- wherein a circumference of the first body part continuously decreases from the first connection section to an end of the root, and a circumference of the second body part continuously increases from the tip towards the second connection section;
- wherein the first connection section and the second connection section have a conical geometry configured to insert one connection section into the other connection section, the conical geometry of the first connection section defined by an outer circumference gradually decreasing towards the split plane, and the conical geometry of the second connection section defined by an inner circumference gradually increasing towards the split plane.
