Abstract

An aircraft for transporting a plurality of cargo containers comprising a forward fairing, an empennage and a spine disposed between the forward fairing and the empennage. The spine is made of a lightweight structure such that the aircraft has insufficient rigidity to withstand bending and tortional loads in flight. A cargo assembly comprising a plurality of modular cargo units is structurally and detachably mounted onto the spine to provide the additional structure to the aircraft required for it to fully withstand the bending and tortional loads of the aircraft in flight. Mounts may be provided to detachably engage the cargo assembly to the spine of the aircraft.

Claims

1. An aircraft for transporting a plurality of cargo containers comprising:

a forward fairing;

an empennage;

a spine disposed between the forward fairing and the empennage; and

a cargo assembly configured to be structurally and detachably integrated with the spine, the cargo assembly comprising a plurality of cargo containers of the same or of different sizes, the plurality of cargo containers each comprising a plurality of attachment points to structurally integrate adjacent cargo containers to one another to provide rigidity to the resulting cargo assembly;

wherein the spine has a lightweight structure such that the aircraft has sufficient rigidity to withstand bending and tortional loads in flight when unloaded with the cargo assembly;

wherein the spine has insufficient rigidity to itself withstand bending and tortional loads in flight when loaded with the cargo assembly; and

wherein the cargo assembly provides additional rigidity to the spine required for the aircraft to fully withstand bending and tortional loads in flight when the cargo assembly is structurally integrated with the spine.

2. The aircraft of claim 1, wherein the cargo assembly is comprised of any one or a combination of modular structural frames and cargo containers.

3. The aircraft of claim 1, further comprising one or more trusses coupling the cargo assembly to the spine.

4. The aircraft of claim 1, further comprising fairings to enclose the cargo assembly mounted on the spine.

5. The aircraft of claim 1, further comprising mounts to detachably engage and structurally couple the cargo assembly to the spine.

6. The aircraft of claim 5, wherein the mounts are disposed on the underside of the spine to detachably suspend the cargo assembly therefrom.

7. The aircraft of claim 6, wherein the mounts are actuated between a first and second position, wherein in the first position, the mounts structurally engage the cargo assembly to the spine and wherein in the second position, the mounts disengage and therefore release the cargo assembly from the spine.

8. The aircraft of claim 7, further comprising a control to alternatively actuate the mounts between the first and second positions.
