Description / Abstract:
This SAE Aerospace Information Report (AIR) provides background
information, technical data and related technical references for
minimization of electrostatic hazards in aircraft fuel systems.
Techniques used to minimize the electrostatic hazard include:
a. Reducing fueling rate into tank bays including use of
multiple refueling inlet nozzles.
b. Reducing refuel plumbing flow velocities.
c. Introducing fuel into the tank at a low velocity near the
bottom and directing it to impinge upon a grounded conducting
surface.
d. Avoiding electrically isolated conductors in the fuel
tank.
e. Using conductivity additives in the fuel.
