Abstract

A method of forming a rotor blade, including forming at least one of a partial upper skin, a partial lower skin, and a partial support network using an additive manufacturing process; and forming a first receptacle in at least a one of the partial upper skin, the partial lower skin, and the partial support network using the additive manufacturing process. The first receptacle is configured to receive of at least one of an electronic component and a mechanical component. In some embodiments, there is a method of manufacturing a rotor blade that includes forming a first locating receptacle in at least one of the upper skin, the lower skin, and the support network using the additive manufacturing process; and positioning at least one of the upper skin, the lower skin, and the support network in a desired position on a fixture based, in part, on the first locating receptacle.

Claims (24)

1. A method of forming a rotor blade, comprising:

forming at least one of a partial upper skin, a partial lower skin, and a partial support network from a solidified layerwise base material using an additive manufacturing process; and

forming a first receptacle in at least a one of the partial upper skin, the partial lower skin, and the partial support network from the solidified layerwise base material using the additive manufacturing process;

disposing a weight and/or a plurality of weights in the first receptacle; and

filling the first receptacle with a filler material that surrounds the weight and/or the plurality of weights, the filler material comprises a polymeric material dissimilar to the solidified layerwise base material.

2. The method according to claim 1 , wherein the step of forming the first receptacle in at least one of the partial upper skin, the partial lower skin, and the partial support network using an additive manufacturing process comprises:

forming a first receptacle surface in at least one of the partial upper skin, the partial lower skin, and the partial support network.

3. The method according to claim 1 , further comprising:

forming a second receptacle in at least one of the partial upper skin, the partial lower skin, and the partial support network using the additive manufacturing process;

wherein the second receptacle is configured to receive of at least one of a first electronic component and a first mechanical component.

4. The method according to claim 3 , further comprising:

disposing at least one of the first electronic component and the first mechanical component in the second receptacle.

5. The method according to claim 4 , further comprising:

filling at least a portion of the second receptacle with the filler material.

6. The method according to claim 4 , further comprising:

filling all of the second receptacle with the filler material such that at least one of the first electronic component and the first mechanical component is embedded within the second receptacle.

7. The method according to claim 1 , further comprising:

forming at least one of a full size upper skin, a full size lower skin, and a full size support networking using the additive manufacturing process.

8. The method according to claim 7 , wherein the first receptacle is partially through at least one of the full size upper skin, the full size lower skin, and the full size support network.

9. The method according to claim 7 , wherein the first receptacle extends through at least one of the full size upper skin, the full size lower skin, and the full size support network.

10. The method according to claim 7 , wherein the first receptacle is disposed within at least one of the full size upper skin, the full size lower skin, and the full size support network.

11. The method according to claim 1 , wherein the additive manufacturing process comprises at least one of the following: electron beam melting, selective laser sintering, selective laser melting, stereolithography, direct metal laser sintering, three-dimensional printing, fused deposition modeling, laser curing and lasered engineered net shaping.

12. The method according to claim 3 , wherein the first electronic component comprises at least one of the following: an electric wire, a heater element, a light emitting device.

13. The method according to claim 3 , wherein the first mechanical component comprises at least one of the following: a securing member, fastener, an abrasion strip, and an actuator.
