Flight Assignment/Project Notes: NOTE: Gap changes per IRP Rev E (Ed., 3/19/14)

NOTE: period of performance information updated per M. Canga/JSC (previously listed as 6/18/2012-9/30/2013)--Ed., 7/2/13

Task Description: Aims:

1. To develop food product parameters to meet nutritional, acceptability, stability, and suit interface criteria.

2. To test several concepts for dispensing liquid through a feed port into a pressurized suit.

AFT will receive energy requirements and nutritional requirements from HHC (Nutritional Biochemistry Laboratory). The food parameters that enable compatibility with the in-suit feeding system will be defined by interfacing with Crew Survival Systems (CSS).

Rationale for HRP Directed Research: This research is directed because it contains highly constrained research, which requires focused and constrained data gathering and analysis that is more appropriately obtained through a non-competitive proposal.

Research Impact/Earth Benefits: 0

Task Progress & Bibliography Information FY2014 
Task Progress: In a contingency cabin depressurization event, it is expected that crewmembers would be in a pressurized suit for up to 144 hours, requiring nutrition to be safely delivered against a pressure differential of 4 psi. The Advanced Food Technology (AFT) group sought to develop both a prototype fluid delivery system that would overcome the pressure differential and guidelines for a nutritional beverage compatible with the delivery system. Two prototypes were developed and analyzed. The bag-in-bag (BiB) prototype, designed to equalize the suit pressure with the beverage pouch and enable a crewmember to drink normally, was operated successfully in both vacuum chamber and suited subject tests. The Boa restrainer pouch, designed to provide mechanical leverage to overcome the pressure differential, was not successful, and recommendations for improved performance have been offered. Guidelines for developing contingency beverage prototypes, including viscosity and rehydration properties, were compiled based on their compatibility with the delivery hardware. Contingency beverage shelf life predictions were calculated based on generated vapor sorption isotherm curves. Evaluation results and food product parameters have the potential to be used to improve future prototype designs and develop complete nutritional beverages for contingency events and extended EVAs.
