Abstract

A cargo management system is provided comprising an air cushion cargo shuttle, an air blower configured to blow air beneath the air cushion cargo shuttle, and an inductive charging receiver on the cargo shuttle. In various embodiments, an energy storage module may be electrically coupled to the inductive charging receiver. A wireless charging station may inductively couple with the inductive charging receiver. The inductive charging receiver may include a first resonant coil, and the wireless charging station may include a second resonant coil. The wireless charging station may switch on in response to the air cushion cargo shuttle entering a desired range. A floor panel may rest beneath the air cushion cargo shuttle with the wireless charging station beneath the floor panel. The floor panel may comprise at least one of a composite material or a metallic material.

First claim

What is claimed is:

1. A cargo management system for an aircraft, comprising:
an air cushion cargo shuttle;
a centrifugal air blower configured to blow air beneath the air cushion cargo shuttle;
a power drive unit coupled to the air cushion cargo shuttle;
a pinion coupled to the power drive unit and engaging teeth on a rack;
an inductive charging receiver on the air cushion cargo shuttle; and
an energy storage module electrically coupled to the inductive charging receiver and configured to power the centrifugal air blower and the power drive unit.

2. The cargo management system of claim 1 , further comprising a wireless charging station configured to inductively couple with the inductive charging receiver.

3. The cargo management system of claim 2 , wherein the inductive charging receiver comprises a first resonant coil and the wireless charging station comprises a second resonant coil.

4. The cargo management system of claim 2 , wherein the wireless charging station is configured to switch on in response to the air cushion cargo shuttle entering a range of the wireless charging station.

5. The cargo management system of claim 2 , further comprising a floor panel beneath the air cushion cargo shuttle, wherein the wireless charging station is mounted beneath the floor panel.

6. The cargo management system of claim 5 , wherein the floor panel comprises a composite material.

7. A cargo shuttle of an aircraft cargo system, comprising:
a first energy storage module;
an inductive charging receiver electrically coupled to the first energy storage module;
a first shuttle drive unit electrically coupled to at least one of the first energy storage module or the inductive charging receiver, wherein the first shuttle drive unit is configured to translate the shuttle forward and aft in the aircraft cargo system;
a second shuttle drive unit electrically coupled to at least one of the first energy storage module or the inductive charging receiver, wherein the second shuttle drive unit is configured to accelerate cargo on the cargo shuttle; and
an air blower on electrically coupled to at least one of the inductive charging receiver or the first energy storage module.

8. The cargo shuttle of claim 7 , wherein the inductive charging receiver comprises a resonant coil.

9. The cargo shuttle of claim 7 , further comprising a second energy storage module electrically coupled to the inductive charging receiver.

10. The cargo shuttle of claim 9 , wherein the second energy storage module is electrically coupled to the first energy storage module.

11. The cargo shuttle of claim 7 , further comprising a power drive unit electrically coupled to the first energy storage module.
