Abstract

The present disclosure is directed to a blade sleeve for a blade tip of a rotor blade of a wind turbine. The blade sleeve includes a rapid-prototyped body having a pressure side, a suction side, a first open span-wise end, a closed leading edge, and a trailing edge. Further, the body is slidable onto the blade tip of the rotor blade. In addition, the blade sleeve includes at least one additional rapid-prototyped feature integral with the body.

Claims (12)

1. A blade sleeve for a blade tip of a rotor blade of a wind turbine, the blade sleeve comprising: a rapid-prototyped body having a pressure side, a suction side, a first open span-wise end, a closed leading edge, and a trailing edge, the body being slidable onto the blade tip of the rotor blade; and, at least one additional rapid-prototyped aerodynamic feature formed integrally with the body on an outer surface thereof wherein the at least one additional rapid-prototyped aerodynamic feature forms a discontinuity in the outer surface thereof, the discontinuity defining one of a vortex generator, a drain hole, a boundary layer energizer, a fence, a serrated leading edge, or a serrated trailing edge.

2. The blade sleeve of claim 1 , wherein the trailing edge is separated along a complete length of the trailing edge.

3. The blade sleeve of claim 1 , further comprising one or more rapid-prototyped structural or attachment features.

4. The blade sleeve of claim 3 , wherein the one or more rapid-prototyped structural or attachment features comprise at least one of one or more leaf springs or one or more internal or external recesses.

5. The blade sleeve of claim 4 , wherein the one or more leaf springs extend from an inner surface of at least one of the pressure side or the suction side of the body.

6. The blade sleeve of claim 4 , wherein the one or more external recesses are formed in an outer surface of at least one of the pressure side or the suction side of the body or in the closed leading edge of the body.

7. The blade sleeve of claim 6 , further comprising a lightning receptor within one or more of external recesses.

8. The blade sleeve of claim 7 , further comprising a second open span-wise end opposite the first open span-wise end, wherein the rotor blade is configured to extend at least partially through the second open span-wise end.

9. The blade sleeve of claim 6 , further comprising a fiber-reinforced structural feature within one or more of the external recesses.

10. The blade sleeve of claim 8 , wherein the one or more internal recesses are formed in an inner surface of at least one of the pressure side or the suction side of the body or in the first open span-wise end and the second open span-wise end of the body, wherein the blade sleeve further comprises double-side tape within one or more of the internal recesses.

11. The blade sleeve of claim 4 , wherein the one or more structural components comprise at least one of the pressure side or the suction side of the body comprising a double-wall configuration having an inner wall and an outer wall with internal ribs extending between the inner and outer walls.

12. The blade sleeve of claim 11 , wherein the internal ribs form one or more holes or channels configured to receive an adhesive that secures the blade sleeve to the blade tip of the rotor blade.
