Abstract

An airborne cargo-carrying apparatus includes support and lower structural frames; a retaining mechanism securing a cargo carrier to the support frame; collapsible nose and tail cones coupled to the frames; flexible side panels coupled to the cones and frames; and a cargo door mounted on the lower structural frame. The support frame includes a top panel. The cones and panels are arranged—with the cones collapsed, side panels folded, and cargo door open—to enable the support frame and the cargo carrier to be secured together with the retaining mechanism engaged. The cones, panels, and cargo door are arranged—with the cones expanded, side panels unfolded, and cargo door closed—to substantially envelop the cargo carrier secured to the support frame within an aerodynamic enclosure.

Claims

1. An apparatus for carrying airborne cargo, the apparatus comprising:

(a) a support frame suspended from an aircraft and including a top panel;

(b) a retaining mechanism arranged on the support frame configured to engage a cargo carrier;

(c) a collapsible nose cone coupled to a front end of the support frame;

(d) a lower structural frame coupled to the nose cone;

(e) flexible side panels, each side panel being connected to corresponding sides of the support frame and lower structural frame and coupled to the nose cone; and

(f) a cargo door mounted on the lower structural frame,

(g) wherein the nose cone, top panel, and side panels, when arranged with the nose cone collapsed, the side panels folded, and the cargo door open, enable the support frame and the cargo carrier to be relatively positioned in a secured-together fashion with the retaining mechanism engaged, and

(h) wherein the nose cone, top panel, side panels, and cargo door, when arranged with the nose cone expanded, the side panels unfolded, and the cargo door closed, substantially envelop the cargo carrier secured to the support frame within an aerodynamic enclosure.

2. The apparatus of claim 1 further comprising a collapsible tail cone coupled to a rear end of the support frame and a rear end of the lower structural frame, wherein the flexible side panels are coupled to the tail cone and the tail cone forms a portion of the aerodynamic enclosure.

3. The apparatus of claim 2 wherein the tail cone includes an aerodynamic stabilization structure.

4. The apparatus of claim 2 wherein each of the nose and tail cones comprises corresponding top and bottom cone halves joined together at their respective distal portions by a corresponding hinge.

5. The apparatus of claim 4 wherein each of the nose and tail cones comprises a corresponding jack screw coupled to the hinge and corresponding top and bottom A-frames pivotably connected at their respective distal ends to each other and to a member threadedly engaged to the corresponding jack screw, wherein proximal ends of the top and bottom A-frames are pivotably connected to ends of the support frame and lower structural frame, respectively.

6. The apparatus of claim 2 wherein the interior of the aerodynamic enclosure is pressurized.

7. The apparatus of claim 2 wherein the top panel, side panels, cargo door, nose cone, or tail cone comprises fabric.

8. The apparatus of claim 1 wherein the retaining mechanism includes a plurality of locking mechanisms arranged to engage receptacles of an ISO-standard shipping container.

9. The apparatus of claim 1 further comprising a plurality of cables and corresponding winches arranged so as to guide the support frame and cargo carrier to be relatively positioned in a secured-together fashion with the retaining mechanism engaged.

10. A method for carrying airborne cargo, the method comprising:

(a) positioning over a cargo carrier, a support frame with a collapsed collapsible nose cone, folded flexible side panels, and an open cargo door,

(i) wherein the support frame is suspended from an aircraft and includes a top panel,

(ii) wherein the nose cone is coupled to front ends of the support frame and a lower structural frame,

(iii) wherein the side panels are connected to sides of the support and structural frames and coupled to the nose cone, and

(iv) wherein the cargo door is mounted on the lower structural frame;

(b) engaging a retaining mechanism on the support frame with a cargo carrier to secure the cargo carrier to the support frame; and

(c) substantially enveloping within an aerodynamic enclosure the cargo carrier secured to the support frame, by expanding the nose cone, unfolding the flexible side panels, and closing the cargo door.

11. The method of claim 10 further comprising thereafter:

(d) exposing the cargo carrier by opening the cargo door, collapsing the nose cone, and folding the flexible side panels;

(e) disengaging the retaining mechanism on the support frame from the cargo carrier to release the support frame from the cargo carrier; and

(f) removing the support frame from the cargo carrier.

12. The method of claim 10 wherein a collapsible tail cone is coupled to a rear end of the support frame and a rear end of the lower structural frame, and wherein the flexible side panels are coupled to the tail cone and the tail cone forms a portion of the aerodynamic enclosure.

13. The method of claim 12 wherein the tail cone includes an aerodynamic stabilization structure.

14. The method of claim 12 wherein each of the nose and tail cones comprises corresponding top and bottom cone halves joined together at their respective distal portions by a corresponding hinge.

15. The method of claim 14 wherein each of the nose and tail cones comprises a corresponding jack screw coupled to the hinge and corresponding top and bottom A-frames pivotably connected at their respective distal ends to each other and to a member threadedly engaged to the corresponding jack screw, wherein proximal ends of the top and bottom A-frames are pivotably connected to ends of the support frame and lower structural frame, respectively.

16. The method of claim 12 wherein the interior of the aerodynamic enclosure is pressurized.

17. The method of claim 12 wherein the top panel, side panels, cargo door, nose cone, or tail cone comprises fabric.

18. The method of claim 10 wherein engaging the retaining mechanism includes engaging receptacles of an ISO-standard shipping container with a plurality of locking mechanisms on the support frame.

19. The method of claim 10 further comprising employing a plurality of cables and corresponding winches to guide the support frame and the cargo carrier to be relatively positioned in a secured-together fashion with the retaining mechanism engaged.
