Modular Inter-Modal Platform for Cargo Aircraft Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current material handling systems require extensive support equipment and modifications to transport cargo across different modes (air, sea, rail, road) and are limited in capacity and offloading capabilities, especially at austere airfields lacking heavy equipment, leading to complex and costly operations.
Innovation Solution
A modular inter-modal platform (MIP) that interfaces with ISO containers, PLS truck-and-trailer systems, and cargo aircraft's 463L rail and pallet locking system, allowing seamless loading and unloading without large cranes and enabling combat offloads, with extendable rails and drop-down rail assemblies for compatibility with various transport systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If married 463L pallets are used to transport CROPs on cargo aircraft, then the cargo can be transported via air, but the system requires heavy equipment (cranes and K-loaders) to be airlifted to loading and unloading sites, increasing operational complexity
Solution Approach 1:
The CROP is designed with an interface structure that directly interfaces with the aircraft cargo roller system, acting as an intermediary that eliminates the need for married pallets and heavy lifting equipment. The interface structure includes rollers that engage with the aircraft's roller conveyor system, allowing the CROP to be loaded and unloaded directly without requiring cranes or K-loaders.
2Adaptability or versatility
If married 463L pallets are used to transport CROPs, then cargo can be transported, but combat offloads are prohibited and delivery is limited to locations with heavy material handling equipment
Solution Approach 1:
The interface structure with rollers serves as a mediator between the CROP and the aircraft cargo system, enabling combat offloads by allowing the CROP to roll off the loading ramp while the aircraft is moving, which was previously prohibited with married pallet systems.
3Adaptability or versatility
If CROPs are loaded onto married 463L pallets using heavy equipment, then cargo can be transported, but the delivery to austere airfields requires multiple flights to transport equipment and cargo separately
Solution Approach 1:
The interface structure with rollers acts as an intermediary that enables direct loading of CROPs onto aircraft without requiring pre-positioned heavy equipment, allowing single-flight delivery to austere airfields and eliminating the need for multiple flights to transport equipment and cargo separately.
4Adaptability or versatility
If conventional pallet systems are used, then cargo can be transported on cargo aircraft, but the carrying capacity of the C-17 is limited to only three CROPs in the center of the aircraft
Solution Approach 1:
The interface structure is designed with universal compatibility to interface with various cargo aircraft roller systems, not just the C-17 center position. This multi-functionality allows CROPs to be positioned and secured in multiple locations within the aircraft cargo bay, maximizing cargo capacity beyond the limitation of only three CROPs in the center.

AI summary
A pallet system for loading and supporting cargo is provided. The pallet system includes a cargo pallet having an upper surface, a lower surface along with a pair of oppositely disposed longitudinal sides having forklift slots generally formed between the upper and lower surfaces, and a pair of oppositely disposed ends generally interconnecting said upper surface and said lower surface. A plurality of drop-down rails is configured to convert the lower surface from a flat bottom to a non-planar bottom. A plurality of extendable rails is used to extend a width of the cargo pallet. A locking mechanism enables the cargo pallet to be coupled to another cargo pallet. A collapsible bale arm assembly can be removed from the cargo pallet when the cargo pallet is stored.
