Investigation of Electrostatic Charge in Hose Lines
Abstract
Current military specifications for collapsible hose used in Army fuel hose line systems, such as the Assault Hose line System (AHS) and the developmental Rapidly Installed Fuel Transfer System (RIFTS) require a means to maintain conductivity/electric bond throughout the length of the hose line. A wire embedded in the hose typically provides this conductive path for static charge to safely dissipate to ground. The need and value for this conductive wire in hose lines have been questioned particularly given the type of fuels used by the military today. This work provides an engineering assessment, based on experiments and analysis that shows that the RIFTS hose line can be safely operated without a continuous grounding system (bond wire) when operated under conditions for which it was designed. It is also shown that the breakdown potential of the hose is well above voltages generated by the triboelectric effect and thus electrical breakdown is not expected.
