Originally developed for military applications, the G457 Automatic Helicopter Refueling Nozzle provides a robust and reliable solution for hot refueling operations, where fueling is conducted with rotors turning. Designed with safety and operational efficiency in mind, this nozzle prevents accidental fuel delivery into engine air intakes, ensuring safe and precise fueling procedures.

Compliance and Standards:

  • Designed to meet stringent NATO specifications, ensuring reliability and compatibility for military and commercial applications.

Key Features and Benefits:

  • Hot Refueling Capability: Supports fueling operations with rotors turning, minimizing downtime and reducing turbine cold starts. Commercial helicopter operators can achieve significant cost savings through reduced wear and tear on turbine systems.

  • Enhanced Safety Mechanisms: Incorporates advanced safety features to prevent accidental spillage and ensure smooth operation.

Safety and Performance Features:

  • Proximity Lever (Dead Man Control): Automatically ceases fuel flow upon nozzle withdrawal from the filler neck, enhancing operational safety.

  • High-Level Shut-Off: Integrated fuel sensor within the spout provides automatic shut-off, including an anti-froth device to ensure smooth operation.

  • Manual Override Function: Allows operators to fill tanks to their maximum capacity when necessary.

  • Filtration and Protection: Equipped with a 100-mesh inlet strainer, dust cap, and grounding wire for added protection against contaminants and static discharge.

  • All-Weather Durability: Features a black anodized finish, providing corrosion resistance and protection against extreme weather conditions.

  • Spout Options: Offered with curved or straight spouts, with additional configurations available upon request.

  • Inlet Variations: Compatible with either female ISO or female NPT inlets.

  • Ground Cable Lengths: Customizable ground cable lengths are available to meet specific operational requirements.

  • Temperature Resistance: Tested for performance in temperatures as low as -30°C (-22°F).

  • Splashguard Material: Constructed with fuel-resistant Buna-N material to withstand exposure to fuel and environmental factors.

  • Shut-Off Flow Rate: Maintains high-level shut-off functionality at flow rates as low as 37.8 liters per minute (10 US gallons per minute).

  • Pressure Handling: Capable of operating under pressures up to 110 psi, ensuring compatibility with high-pressure fueling systems.

  • Integrated Swivel Mechanism: Provides ease of handling and maneuverability during refueling operations.
