CFD Efforts to Improve Transport of Meals and Water in Theatre
• Current CFD projects
• Optimized Insulated Food Container (IFC)
• Optimal Low Cost Insulated Beverage Dispenser (IBD)
• Long Range Patrol Water Container (LRPWC)

Optimized Insulated Food Container (IFC)
Optimized Insulated Food Container (IFC)
• Description of IFC
• IFC designed to transport UGR-A and UGR-H&S rations to remote locations from field kitchens, while maintaining food product within safe temperatures for at least 4 hours under -25F ambient
• Current design replaced RFC fielded with KCLFF
• Optimized IFC designed to met/exceed existing performance requirements, and reduce weight and volume for field feeding operations

Optimized Insulated Food Container (IFC)
• Improved capabilities of Optimized IFC
• Reduce the weight of the current IFC by 20%, and the volume by 14%
• Nesting capability will reduce IFC storage volume by 25%
• Smaller and lighter IFC’s will allow more containers to be carried onboard current field kitchens and the proposed Assault Kitchen

Optimized Insulated Food Container (IFC)
• Status of Optimized IFC
• Prototypes were tested with an independent test agency for thermal performance, vibration exposure and vibration impact, and they were evaluated with the 10th Mountain Division at Fort Drum
• Received concurrence from the Army’s Center for Excellence and Subsistence for fielding new design, and revised the CID to include the Optimized design
• Cambro Manufacturing completed the mold construction for the Optimized IFC and now has the item available for procurement

Optimal Low Cost Insulated Beverage Dispenser (IBD)
Optimal Low Cost Insulated Beverage Dispenser (IBD)
• Description of IBD
• Current IBD are fabricated using rotational molding, which produce parts that are poor in tolerance and surface finish
• CORANET Program funded a 28-month effort for TAMU and Cambro to design and produce the IBD using improved mold technology (multinozzle structural web or Roto-mold)
• These technologies will provide a low cost alternative that will reduce unit cost and delivery time to produce
• CORANET effort will upgrade the design to meet desired mechanical and thermal characteristics specified in the CID

• Status of Optimized IFC
• CORANET project broken down into two Phases. Phase I is 14 months and Phase II is 14 months
• Currently completed the final design of the Alpha Prototype
• Recommend manufacturing prototype using Roto-Mold process
• If this Mold process successful, initial prototype can be used as the Beta prototype
• This will reduce required steps in Phase II of the CORANET project

Long Range Patrol Water Container (LRPWC)))
Long Range Patrol Water Container (LRPWC)))
• Description of LRPWC
• Current 5-gallon plastic water can is a solid rectangular design
• Two piece design susceptible to failure at seam
• Full and empty volume of can is the same
• LRPWC designed to improve cleanability, reduce water waste, and improve survivability of can after air drop

• Improved capabilities of LRPWC
• Would need just one LRPWC
• High stress collapsible water bag (HSCWB) could act as “refills”
• HSCWB can be rolled up
• Collapsed LRPWC signal for re-supply
Currently for 20 gallons Re-supply for 20 gallons After 20 gallons consumed

Long Range Patrol Water Container (LRPWC)
• Status of LRPWC
• Project funded under Continuous Product Improvement (CPI) Program, to develop a new product design to meet evolving requirements
• Completed a Phase I CPI Program effort to develop an Alpha prototype. Submitted a Phase II CPI proposal to include Marine Corps comments and compare to potential COTS items
• Preparing a proposal to transition to the ManTech program to develop a cost effective production design
