Abstract

A system and method determine a size and a shape for identical geodesic modules that are used to form a structure. The system and method may include analyzing input data regarding a size and a shape of the structure to be formed, and determining the size and the shape for each of the identical geodesic modules based on the size and the shape of the structure to be formed. The structure may include a framework including the identical geodesic modules. Each of the geodesic modules has a size and a shape that are the same as all of the other of the geodesic modules. A forming system and method position a framework and a covering skin of the structure in relation to a mandrel, and drill and rivet the framework to the covering skin with a plurality of operating heads.

First claim

What is claimed is:

1. A structure comprising:
a framework that forms at least a portion of a fuselage of an aircraft and including a plurality of identical geodesic modules, wherein each of the plurality of identical geodesic modules comprises a plurality of interconnected frame segments that are identical in size and shape, wherein the plurality of interconnected frame segments comprise four interconnected frame segments defining a geodesic area therebetween.

2. The structure of claim 1 , wherein the framework is a framework for a constant section.

3. The structure of claim 2 , wherein the constant section comprises a constant curvature and constant cross-sectional radius between opposed circular ends.

4. The structure of claim 1 , wherein at least one feature is configured to fit within the geodesic area.

5. The structure of claim 4 , wherein the at least one feature comprises a window.

6. The structure of claim 1 , wherein the geodesic area is diamond shaped.

7. The structure of claim 1 , further comprising a covering skin that is secured over the framework.

8. The structure of claim 1 , wherein each of the plurality of identical geodesic modules has a size and a shape that are the same as sizes and shapes of all other of the plurality of identical geodesic modules.

9. The structure of claim 1 , wherein only the four interconnected frame segments define the geodesic area therebetween.

10. The structure of claim 1 , wherein each of the four interconnected frame segments comprises:
a rail having a first end and a second end;
a first connection channel proximate to the first end; and
a second connection channel proximate to the second end.

11. A method of forming a structure, the method comprising:
providing a plurality of identical geodesic modules, wherein the providing comprises forming each of the plurality of geodesic modules with a plurality of interconnected frame segments that are identical in size and shape, wherein the plurality of interconnected frame segments comprise four interconnected frame segments defining a geodesic area therebetween;
connecting the plurality of identical geodesic modules together to form a framework; and
forming at least a portion of a fuselage of an aircraft with the framework.

12. The method of claim 11 , wherein the framework is a framework for a constant section.

13. The method of claim 11 , wherein the constant section comprises a constant curvature and constant cross-sectional radius between opposed circular ends.

14. The method of claim 11 , further comprising accommodating at least one feature within the geodesic area.

15. The method of claim 14 , wherein the at least one feature comprises a window.

16. The method of claim 11 , wherein the geodesic area is diamond shaped.

17. The method of claim 11 , further comprising securing a covering skin over the framework.

18. The method of claim 11 , wherein each of the plurality of geodesic modules has a size and a shape that are the same as sizes and shapes of all other of the plurality of identical geodesic modules.

19. The method of claim 11 , wherein only the four interconnected frame segments define the geodesic area therebetween.

20. The method of claim 11 , wherein each of the four interconnected frame segments comprises:
a rail having a first end and a second end;
a first connection channel proximate to the first end; and
a second connection channel proximate to the second end.
