Abstract

Provided are aircraft for transporting intermodal containers and methods of operating such aircraft including methods of loading and unloading the containers. An aircraft includes a fuselage having a cargo space for receiving and supporting intermodal containers. The containers are oriented in the transverse direction in the cargo space or, more specifically, in a direction normal to the longitude direction that extends from the nose to the tail of the aircraft. The aircraft may transport standard 20-foot or 40-foot containers or lighter version of such containers that otherwise have the same form and features as the standard intermodal containers. The intermodal containers may be loaded through an opening in the bottom of the fuselage. Specifically, intermodal containers may be arranged into a row. The aircraft may be then rolled over this row of the containers and lowered onto the containers followed by engaging container corners.

Claims

1. An aircraft for transporting intermodal containers, the aircraft comprising:

a fuselage comprising a cargo space,

the fuselage extending in a longitude direction,

the cargo space configured to receive and support the intermodal containers during operation of the aircraft such that each of the intermodal containers extends in a transverse direction while inside the cargo space,

the intermodal containers having a length of at least 30 feet measured in the transverse direction and a width not exceeding 15 feet in the longitudinal direction,

wherein the fuselage has an opening at a bottom of the fuselage, the opening providing access to the cargo space and used to receive the intermodal containers into the cargo space.

2. The aircraft of claim 1, wherein the cargo space is an unpressurized cargo space.

3. The aircraft of claim 1, wherein the opening allows receiving all of the intermodal containers into the cargo space simultaneously.

4. The aircraft of claim 1, further comprising a bottom cover detachably connected to the fuselage and covering the opening at the bottom of the fuselage.

5. The aircraft of claim 1, wherein the fuselage comprises a frame, the frame comprising top supporting mechanisms for engaging with top corners of the intermodal containers.

6. The aircraft of claim 5, wherein the top supporting mechanisms are configured to be inserted into the top corners of the intermodal containers in a vertical direction.

7. The aircraft of claim 5, wherein the frame further comprises bottom supporting mechanisms for engaging with bottom corners of the intermodal containers, wherein the bottom supporting mechanisms are configured to be inserted into the bottom corners of the intermodal containers in the transverse direction.

8. The aircraft of claim 1, wherein bottom surfaces of the intermodal containers remain exposed during operation of the aircraft.

9. The aircraft of claim 1, further comprising a landing gear attached to the fuselage, wherein the landing gear in an extended position provides a ground clearance of at least about 8 feet to the fuselage.

10. The aircraft of claim 9, wherein the landing gear has a track greater than the length of the intermodal containers.

11. The aircraft of claim 9, wherein the landing gear is configured to change ground clearance of the fuselage by at least about 8 feet when receiving the intermodal containers into the cargo space.

12. The aircraft of claim 1, wherein the fuselage has an airfoil shape producing an aerodynamic force.

13. The aircraft of claim 1, wherein the fuselage has a height that is at least twice less than a width of the fuselage.
