Abstract

An aircraft for carrying cargo in one or more containers. The aircraft includes a fuselage structure having a plurality of nodes and a plurality of elements connecting the nodes to form a space frame in which to carry cargo. At least some of the nodes are positioned in the space frame based on dimensions of the one or more containers. The fuselage structure is more compact, lighter and less expensive compared to conventional semi-monocoque fuselages.

Claims

1. An aircraft for carrying containerized cargo, the aircraft comprising:

a space frame forming a fuselage, the space frame including a plurality of nodes, each of the nodes connecting a plurality of elements of the space frame, the space frame enabling at least one structural component of the aircraft to be at least partially supported directly from at least a first one of the nodes of the space frame,

at least a subplurality of the nodes being selectively positioned in the space frame based on dimensions of a standardized shipping container, and the subplurality of nodes further being secured to predetermined portions of the standardized shipping container to enable the shipping container to be fully supported by the subplurality of nodes;

wherein the space frame comprises linear elements and wherein the fuselage is configured such that essentially all of the loads flow through the linear elements.

2. The aircraft of claim 1, wherein the fuselage structure is adapted to carry a plurality of the standardized shipping containers, and wherein at least some of the subplurality of nodes are configured to engage a plurality of corner portions of two or more ones of the plurality of standardized shipping containers to restrain the two or more standardized shipping containers.

3. The aircraft of claim 1, wherein at least some of the dimensions of the one or more standardized containers are modular.

4. The aircraft of claim 1, wherein the space frame is configured to resolve loading by the standardized shipping container independent of a skin of the aircraft.

5. The aircraft of claim 1, wherein the space frame comprises a plurality of trusses providing a plurality of redundant load paths in the frame for the standardized shipping container.

6. The aircraft of claim 1, wherein rotation of a given one of the nodes about a given axis is opposed by at least one element connected at the given one of the nodes and substantially orthogonal to the given axis.

7. The aircraft of claim 6, further comprising a plurality of diagonal elements connected to one or more of the nodes.

8. The aircraft of claim 1, wherein at least some of the nodes prevent transfer of a moment to the elements.

9. The aircraft of claim 1, wherein one of the at least some of the nodes restrains more than one said standardized shipping container.

10. The aircraft of claim 1, further comprising a wing connected with one or more of the nodes of the space frame that forms the fuselage structure.

11. An aircraft for carrying containerized cargo, the aircraft comprising:

a space frame forming a fuselage for the aircraft, the space frame including a plurality of nodes, each of the nodes connecting a plurality of elements to form the space frame, the space frame defining a plurality of rectangular bays for receiving and housing a plurality of standardized shipping containers;

the plurality of rectangular bays further being arranged in a first group at a first elevation and a second group at a second elevation above the first group;

the nodes further being positioned to form the space frame based on length and width dimensions of the standardized shipping containers, to enable at least one said standardized shipping container from each of the first and second groups of rectangular bays to be secured to one another, and further such that each of the secured standardized shipping containers is secured at a plurality of corner portions thereof;

wherein the space frame comprises linear elements and wherein the fuselage is configured such that essentially all of the loads flow through the linear elements.

12. An aircraft for carrying containerized cargo, the aircraft comprising:

a space frame forming a fuselage structure, the space frame including a plurality of nodes, each of the nodes connecting a plurality of elements to form the space frame in a manner such that the space frame is adapted to carry one or more standardized shipping containers therein;

at least some of the nodes positioned in the space frame based on length and width dimensions of the one or more standardized shipping containers to enable supporting each of the one or more standardized shipping containers only at one or more corner portions of each one of the one or more standardized shipping containers, and only at the corner portions located at opposing longitudinal ends of each one of the one or more standardized shipping containers;

wherein the space frame comprises linear elements and wherein the fuselage is configured such that essentially all of the loads flow through the linear elements.
