A pneumatic deployment device (“PDD”) assists in ejecting containerized cargo bundles from a cargo aircraft during an airdrop. The PDD includes a first structure affixed to the aircraft and a second moveable structure, and which is positioned against a cargo bundle, referred to as a CDS bundle. Typically, a series of CDS bundles are positioned along a line in the cargo hold of the aircraft. A pressurized tank provides compress gas to an airbag that is positioned between the first structure and the second structure. Upon reaching the drop location, the gas is release from the tank to the airbag via a hose, inflating the airbag. The airbag pushes the second structure against the CDS bundle, so that the cargo bundles are ejected faster from the aircraft than would otherwise occur.

1. A system for deploying cargo from an aircraft, comprising: rails integrated into an aircraft floor;a structural frame having structural frame flanges on opposing sides of the structural frame, the structural frame flanges configured for attachment to the aircraft floor via the rails;a movable ram connected to the structural frame having movable ram flanges on opposing sides of the movable ram, the moveable ram flanges both attached to the rails and configured to move along the rails attached to the aircraft floor from a first ram position to an aft ram position; andan ejection mechanism connected to the structural frame and the movable ram, the ejection mechanism configured to move the movable ram in an aft direction thereby configured to accelerate a cargo container from a first container position to a second container position. 2. The system of claim 1, further comprising: an airbag configured to receive compressed gas and expand within a volume of the structural frame. 3. The system of claim 2, wherein the airbag is contained within the structural frame and the movable ram. 4. The system of claim 3, wherein the structural frame is configured to receive the movable ram and the movable ram flanges. 5. The system of claim 4, wherein the movable ram comprises a vertically oriented planar structure configured to contact a pallet of the cargo container. 6. The system of claim 2, further comprising a container storing the compressed gas and configured to provide the compressed gas to the airbag. 7. The system of claim 6, further comprising a regulator to control the flow of compressed gas into the airbag and configured to release the compressed gas upon receipt of a signal from a computer coordinating deployment of the cargo. 8. The system of claim 1, wherein the movable ram and movable ram flanges are at least partially contained inside the structural frame when the movable ram is in the first ram position, and the movable ram is deployed from the structural frame when it is in the aft ram position. 9. A pneumatic delivery deployment device comprising: a pair of rails integral with an aircraft floor of a cargo aircraft;a structure having flanges being configured to be affixed to the cargo aircraft via the pair of rails;a ram having ram flanges slideably engaged with the rails, the ram configured to engage a cargo element and movably coupled to the structure configured to slideably disengage with the structure; andan airbag configured to inflate upon receiving pressurized gas located between the structure and the ram, wherein upon inflation the airbag accelerates the ram from the fixed structure. 10. The pneumatic delivery deployment device of claim 9, further comprising: a pressure containment vessel configured to contain pressurized gas;a regulator configured to control a release of the pressurized gas; anda hose configured to convey the released pressurized gas to the airbag. 11. The pneumatic delivery deployment device of claim 10, wherein the airbag is positioned between the structure and the ram. 12. The pneumatic delivery deployment device of claim 11, wherein the airbag is configured to inflate to a volume of at least 3 cubic feet. 13. The pneumatic delivery deployment device of claim 10, wherein the regulator is configured to deflate the airbag after the airbag has inflated. 14. A method for deploying cargo comprising one or more container delivery system (“CDS”) bundles comprising the operations of: flying a cargo aircraft conveying a plurality of CDS bundles slideably engaged within a rail system in a floor of the cargo aircraft; andinflating an airbag positioned between a structure having structure flanges on opposing sides of the structure secured within the rail system in the floor, and a moveable ram at least partially contained within the structure having movable ram flanges on opposing sides of the moveable ram, the moveable ram flanges being slideably engaged within the rail system in the floor of the cargo aircraft, and moving the movable ram from the structure and along the rail system to contact a cargo pallet thereby accelerating the moveable ram and causing at least one of the CDS bundles to accelerate. 15. The method of claim 14 further comprising the operations of: installing the pneumatic deployment device (“PDD”) in a cargo hold of the cargo aircraft, the PDD comprising the structure and the moveable ram, wherein the structure and the moveable ram are positioned vertically with respect to a floor of the cargo aircraft;affixing the structure to the aircraft; andpositioning the one or more container delivery system (“CDS”) bundles in a linear manner such that the first installed CDS bundle is positioned adjacent to the PDD. 16. The method of claim 14, wherein deploying the PDD comprises releasing pressurized gas from a containment vessel thereby inflating the airbag positioned between the structure and the moveable ram. 17. The method of claim 15, wherein the airbag moves the moveable ram away from the structure. 18. The method of claim 15, further comprising: receiving a signal at the PDD from a computer coordinating the cargo deployment and deploying the PDD in response to receiving the signal.
