Abstract

A cargo management system may include an air cushion cargo shuttle, an air cushion cargo shuttle, an air blower configured to blow air beneath the air cushion cargo shuttle and a shuttle drive unit that interacts with a linear guide rail and configured to cause linear motion, wherein the shuttle drive unit is configured for self-propulsion.

First claim

What is claimed is:

1. A cargo management system comprising:
an air cushion cargo shuttle having a cargo surface opposite a bottom surface;
an air blower coupled to the bottom surface of the air cushion cargo shuttle, wherein the air blower is configured to blow air beneath the air cushion cargo shuttle and proximate a floor panel causing separation between the air cushion cargo shuttle and the floor panel; and
a shuttle drive unit coupled to the air cushion cargo shuttle, wherein the shuttle drive unit comprises a pinion that interacts with a linear rack on the floor panel, and wherein a rotational movement by the pinion results in linear motion of the air cushion cargo shuttle along the linear rack.

2. The cargo management system of claim 1 , wherein the bottom surface of the air cushion cargo shuttle defines a volume, and wherein the air blower is configured to blow air into the volume.

3. The cargo management system of claim 1 , wherein the rotational movement of the pinion is driven by a shaft rotated by a motor coupled to the air cushion cargo shuttle.

4. The cargo management system of claim 1 , wherein the floor panel comprises at least one of a composite material or a metallic material.

5. The cargo management system of claim 4 , further comprising a support rail laterally adjacent to the floor panel and disposed in a direction parallel to the linear rack, wherein the support rail is configured to support cargo.

6. The cargo management system of claim 1 , wherein the air blower is a centrifugal air blower.

7. The cargo management system of claim 1 , wherein the air cushion cargo shuttle comprises an air inlet located between the cargo surface and the bottom surface, and wherein the air inlet is in fluid communication with the air blower.

8. The cargo management system of claim 1 , wherein the air blower is controlled by an air blower controller.

9. The cargo management system of claim 8 , further comprising a proximity sensor in electronic communication with the air blower controller, wherein the proximity sensor is configured to measure the proximity of the bottom surface of the air cushion cargo shuttle relative to the floor panel.

10. The cargo management system of claim 9 , wherein the air blower controller is programmed to modulate output of the air blower based on data from the proximity sensor.

11. The cargo management system of claim 1 , wherein the air cushion cargo shuttle comprises a roller coupled to the cargo surface to facilitate movement of cargo with respect to the air cushion cargo shuttle.
