Abstract:

Testing was conducted to reproduce and verify the failure mode experienced with D-I nozzles as used with the HEMMT Tanker Aviation Refueling System and the Advanced Aviation Forward Area Refueling System AAFARS. The 0-I nozzles failed when exposed to high ambient temperatures, which resulted in fuel spillage. D-I nozzles from different manufacturers and in differing configurations with and without hose end regulators HEPR were tested along with a Closed Circuit Refueling CCR nozzle. Also, the effect of connecting 50 feet of fuel hose to a Carter 0-I nozzle was investigated.
