Automatic Hot Refueling Nozzles - G457

The G457 Automatic Helicopter Refueling Nozzle was originally developed for military applications. This nozzle is designed to ensure that fuel cannot be accidentally delivered into the engine air intake during hot refueling (fueling with rotors turning). Commercial helicopter operators will appreciate the significant cost advantages in terms of the reduction in turbine cold starts occurring from the ability to safely refuel with rotors turning.
