2 EATONAerospace Group TF100-127C June 2013 Eaton’s Carter product line includes a number of aircraft pressure fueling nozzles. Model 64048 Pressure Fueling Nozzle is used for Helicopter In-Flight Refueling (HIFR) operations from US naval vessels. These nozzles are identical in appearance to US Army Closed Circuit Refueling (CCR) nozzles but regulate pressure at 45 psig (3.102 bar) instead of 15 psig (1.034 bar) for the Army nozzles. This difference in pressure regulating settings is because U.S. naval aircraft are designed to allow fueling at pressures up to 55 psig, while U.S. Army aircraft are designed to allow fueling at either 15 psig (1.034 bar) or 55 psig (3.792), depending on the model. These nozzles are designed to connect to helicopters and perform hot refueling operations while hovering above ships. The nozzle is designed to connect to helicopters that have receptacles in accordance with U.S. Army drawing C13219E0479 or equivalent. The nozzles provide “tight fill” capability and limits system pressure. Positive interlock is provided. Features • Standard nozzles meet latest US Navy requirements in accordance with the Aircraft Refuleing NATAOPS Manual, NAVAIR 00-80T-109 and Helicopter Procedures for Air Capable Ships, NAVAIR 00-80T-122 • Meets human engineering standards • Positive interlock system — nozzle will not open unless connected and closes automatically when disconnected • Lightweight and rugged construction • Limits pressure to helicopter adapter to 45 psi (3.102 bar) regardless of inlet pressure • Standard meets tan color requirements • Standard Model 64048 meets Type I, Class A requirements, with 100mesh strainer and 2-inch female camlock inlet • Optional, Type I, Class B nozzle, comes with 100mesh strainer, non-valved unisex coupling and dust cap (standard nozzle only) Design Concepts Ordering Data The basic Model 64048 is a Type I, Class A CCR nozzle that meets tan color requirement, with 2-inch female camlock inlet, 100-mesh strainer and 15-foot bonding cable.
