Abstract

A component alignment system for an aircraft includes a first component having a first surface including first shaped projections that repeat in at least two directions along the first surface. The component alignment system also includes a second component having a second surface including second shaped projections that repeat in at least two directions along the second surface. The first shaped projections are complementary to the second shaped projections such that the first surface is translationally and rotationally constrained relative to the second surface when the first and second shaped projections are in an interlocked position.

First claim

What is claimed is:

1. A component alignment system for an aircraft comprising:
a first component having a first surface including a plurality of first shaped projections each having a triangle cross-sectional shape, the first shaped projections repeating in at least two directions along the first surface; and
a second component having a second surface including a plurality of second shaped projections each having an inverted triangle cross-sectional shape, the second shaped projections repeating in at least two directions along the second surface;
wherein, the first shaped projections are complementary to the second shaped projections such that the first surface is translationally and rotationally constrained relative to the second surface when the first and second shaped projections are in an interlocked position;
wherein, the first surface is interlockable with the second surface in a plurality of quantized translational positions along at least two translational degrees of freedom; and
wherein, the first surface is interlockable with the second surface in a single rotational position, the first surface noninterlockable with the second surface in rotational positions other than the single rotational position.

2. The component alignment system as recited in claim 1 wherein the aircraft further comprises a bay door and one of the first or second components further comprises a bay door switch.

3. The component alignment system as recited in claim 1 wherein each of the first and second shaped projections includes three projection interface surfaces configured to engage a respective adjacent projection interface surface of one of the shaped projections in the interlocked position.

4. The component alignment system as recited in claim 1 wherein the quantized translational positions have a quantum translational granularity of less than 0.1 inches.

5. The component alignment system as recited in claim 1 wherein the at least two translational degrees of freedom are parallel to the first and second surfaces.

6. The component alignment system as recited in claim 1 wherein the quantized translational positions are spaced apart by a translational distance proportional to a size of the first and second shaped projections.

7. The component alignment system as recited in claim 1 wherein the first shaped projections further comprise tapered projections.

8. The component alignment system as recited in claim 1 wherein the first and second shaped projections further comprise tapered projections.

9. The component alignment system as recited in claim 1 wherein the first surface forms a first fastener hole and the second surface forms a second fastener hole, the first and second fastener holes configured to receive a fastener to secure the first surface against the second surface; and
wherein the second fastener hole is larger than the first fastener hole such that the fastener is undersized relative to the second fastener hole, thereby allowing for translational adjustment between the first and second components.

10. The component alignment system as recited in claim 1 wherein the first shaped projections have a uniform depth.

11. The component alignment system as recited in claim 1 wherein the first shaped projections have a nonuniform depth.

12. The component alignment system as recited in claim 1 wherein the first and second shaped projections have a uniform depth.

13. The component alignment system as recited in claim 1 wherein the first and second shaped projections have a nonuniform depth.

14. The component alignment system as recited in claim 1 wherein the first and second surfaces are additively manufactured surfaces.

15. The component alignment system as recited in claim 1 wherein the first and second surfaces are 3D printed surfaces.
