FUEL TANK OF AIRCRAFT

摘要

A fuel tank of aircraft capable of suppressing the occurrence of spark on a pipe by the flow of a lightning current therethrough at a lightning strike and of suppressing the charging of a pipe with static electricity due to flow charge with a fuel.  The fuel tank (1) of aircraft in which a storage section is formed utilizing a conductive upper outer plate (5), a conductive lower outer plate (7), and conductive beams (9).  The fuel tank comprises the pipes in the fuel tank such as a fuel replenishing pipe (17), a fuel supply pipe (19), and an inert gas pipe (21) disposed in the storage section and earthed (27) at a plurality of positions; and pipe outer surface layers (31) with semiconductor characteristics which are formed integrally with the outer surfaces of the pipes in the fuel tank such as the fuel replenishing pipe (17), the fuel supply pipe (19), and the insert gas pipe (21), respectively.
