Abstract

Systems, devices, and methods for an extruded wing protection and control surface comprising: a channel proximate a leading edge of the control surface, a knuckle disposed about the channel, a leading void, a trailing void, and a separator dividing the leading void and the trailing void; and a plurality of notches disposed in the extruded control surface proximate the leading edge of the control surface.

Claims (29)

1. A method comprising:

extruding a control surface, wherein the extruded control surface comprises a channel and a knuckle disposed about the channel, wherein the knuckle comprises a semi-circular portion and a leading edge portion, wherein the leading edge portion extends from the semi-circular portion toward a bottom side of the control surface, and wherein an opening of the knuckle formed by the semi-circular portion and the leading edge portion is toward the bottom side of the control surface and open to an outside.

2. The method of claim 1 , wherein the channel is proximate a leading edge of the control surface.

3. The method of claim 1 , wherein the knuckle comprises an opening facing towards a bottom surface of the control surface.

4. The method of claim 1 , further comprising:

cutting the control surface at a set length.

5. The method of claim 4 , further comprising:

milling a plurality of notches into the cut control surface proximate a leading edge of the control surface.

6. The method of claim 4 , further comprising:

attaching a cuff to an end of the cut control surface.

7. The method of claim 6 , further comprising:

receiving the control surface in a first cavity of the cuff.

8. The method of claim 7 , further comprising:

attaching a servo connector to the cuff via a second cavity of the cuff, wherein the second cavity is distal from the first cavity.

9. The method of claim 1 , further comprising:

attaching at least one pin of each clip of a plurality of clips to the knuckle of the extruded control surface.

10. The method of claim 9 , further comprising:

deforming the knuckle to accept the pin.

11. The method of claim 10 , wherein the knuckle is the only part of the extruded control surface that deforms to accept the pin.

12. The method of claim 10 , further comprising:

pivoting the control surface about each pin.

13. The method of claim 9 , wherein each clip of the plurality of clips comprise the at least one pin disposed proximate a base of the clip.

14. The method of claim 13 , wherein each pin of the at least one pin is tapered, and wherein a narrow end of each pin of the at least one pin is distal from the base.

15. The method of claim 1 , wherein the extruded control surface further comprises a leading void.

16. The method of claim 15 , wherein the extruded control surface further comprises a trailing void.

17. The method of claim 16 , wherein the extruded control surface further comprises a separator dividing the leading void and the trailing void.

18. The method of claim 17 , wherein the trailing void is proximate to a trailing edge of the control surface.

19. The method of claim 17 , wherein the separator is narrower in width than an outside width of the control surface.

20. The method of claim 1 , wherein the control surface is made from at least one of: an Ultraviolet (UV) resistant plastic and a polycarbonate-acrylonitrile butadiene styrene (PC-ABS).
