Abstract

A wing for an aircraft includes a first end, a second end, and a skin extending longitudinally from the first end to the second end. The wing also includes at least one channel positioned within the skin and extending longitudinally between the first and second ends. The at least one channel defines a longitudinal translation path for translating at least one electrical power source longitudinally between the first and second ends.

First claim

What is claimed is:

1. A wing for an aircraft, the wing comprising:
a first end comprising an open wing tip comprising an opening;
a second end;
a skin extending longitudinally from the first end to the second end;
at least one channel positioned within the skin and extending longitudinally between the first and second ends, wherein the at least one channel defines a longitudinal translation path for translating at least one electrical power source longitudinally through the opening and between the first and second ends, wherein the at least one channel is configured to allow the at least one electrical power source to provide structural support to the wing; and
an aft spar within the skin and defining a space between the aft spar and the skin, and further comprising a conversion motor disposed within the space, the conversion motor configured to selectively rotate a nacelle.

2. The wing of claim 1 , wherein the wing is ribless.

3. The wing of claim 1 , further comprising the nacelle rotatable between a plurality of orientations to selectively cover and uncover the opening.

4. The wing of claim 1 , further comprising a main spar within the skin, the main spar comprising an I-shape, the main spar configured to at least partially define two channels comprising the at least one channel, each of the two channels configured to receive the at least one electrical power source therein.

5. The wing of claim 1 , further comprising an access panel movable between closed and open states for selectively covering and uncovering the opening, respectively.

6. The wing of claim 1 , wherein the second end includes one of a root or a carry-through region, wherein the at least one channel extends longitudinally from the open wing tip to the one of a root or a carry-through region.

7. The wing of claim 1 , wherein the first and second ends define a wing length, wherein the at least one channel has a channel length substantially equal to the wing length.

8. A wing for a fuselage of an aircraft, the wing comprising:
a first end comprising an open wing tip comprising an opening;
a second end;
a skin extending longitudinally from the first end to the second end; and
at least one channel positioned within the skin and extending longitudinally from the first end and second end, wherein the at least one channel defines a longitudinal translation path for translating at least one electrical power source longitudinally from the first end to the second end;
wherein the wing is configured to be coupled to the fuselage such that the first and second ends are on opposite sides of the fuselage such that the wing is sized to span the fuselage.

9. The wing of claim 8 , further comprising at least one spar positioned within the skin and extending longitudinally between the first and second ends.

10. The wing of claim 9 , wherein the at least one spar at least partially defines the at least one channel.

11. The wing of claim 10 , wherein the at least one spar includes at least one vertical spar web, wherein the at least one channel is defined by the at least one vertical spar web and one of a leading edge or a trailing edge of the wing.

12. The wing of claim 8 , the at least one electrical power source comprising at least one battery positioned within the at least one channel and configured to translate longitudinally between the first and second ends along the longitudinal translation path.

13. The wing of claim 8 , wherein the at least one channel comprises a carry-through region configured to be at least partially above the fuselage.

14. The wing of claim 8 , wherein the at least one channel is free of protrusions extending thereacross.

15. The wing of claim 8 , wherein the at least one channel includes a forward channel and an aft channel.
