Aviation Filtration Technology for the Replacement of Filter Monitors

Description:

TECHNOLOGY AREA(S): Materials 

OBJECTIVE: Develop alternative jet fuel and aviation gasoline filtration/water separation technologies to meet third stage filtration needs due to the impending obsolescence of Super Absorbent Polymer (SAP) filter monitors. 

DESCRIPTION: Due to SAP migration issues in commercial aviation fuel filtration monitor applications, the Energy Institute will cancel EI 1583, Laboratory tests and minimum performance levels for aviation fuel filter monitors, no later than 31 December 2020. EI will be publishing EI 1588 Water Barrier Filtration as one potential drop in alternative method to provide for water and solid particulate contamination defense. Alternative technologies must meet the laboratory tests and minimum performance levels for existing aviation fuel filter monitors, must be compatible with existing filter monitor vessels, and be compatible with military fuel additives. Testing shall include removal of 35 ppm free water when subjected to 50 ppm free water after three minutes of continuous water injection, and removal of an average of 9.74 mg/L particulates when subjected to 10.0 mg/L of a 90:10 blend of A1 ultrafine test dust ISO 12103-1 and R-998 Red Iron Oxide test dust five minutes after continuous particulate injection. The contractor shall develop a pathway for developed textiles and technologies to transition filters and coalescers meeting the requirements of EI 1581, Specifications and laboratory qualification procedures for aviation fuel filter/water separators; and MIL-PRF-52308, Filter-Coalescer Element, Fluid Pressure. 

PHASE I: Develop an approach for the design of technologies meeting the filtration and water removal requirements currently required by fuel monitors operating at flow rates of 50-1200 gpm. Conduct proof of principle experiments supporting the concept and providing evidence of the feasibility of the approach. 

PHASE II: Develop, build, and evaluate filtration and water removal technologies meeting the requirements required for qualification requirements of EI 1589, EI 1588 and MIL-PRF- 52308. Twelve sample of each prototype evaluated to the requirements of EI 1588 and MIL-PRF-52308 shall be provided to the government. 

PHASE III: In addition to military fuel filtration opportunities realized in meeting the performance requirements of MIL-PRF-52308, the technologies developed under this SBIR have significant commercial potential in that existing fuel filtration and water separation monitors, employed on 80-90% of all aircraft hydrant carts in the United States, are qualified under EI 1583 which will need to be replaced by 31 December 2020.
