Abstract
A fuel tank that stores fuel to be fed to a fuel supply destination through a pipe, wherein a whole or a portion of a storage fuel contact portion in contact with the fuel within the fuel tank is subjected to surface finishing for imparting hydrophilicity.
Claims5
A fuel supply apparatus comprising:
- a fuel tank that stores liquid fuel therein, wherein at least a portion of an inner wall of the fuel tank in contact with the liquid fuel is a hydrophilic surface configured to solidify water thereon;
- a drain port that is fluidly coupled to the fuel tank and configured to discharge the water from the fuel tank;
- and
- a fuel pipe attached to the fuel tank, the fuel pipe directing the liquid fuel in the fuel tank to a fuel supply destination, wherein at least a portion of an inner wall of the fuel pipe is made of a material having water repellency, or is subjected to surface finishing for imparting water repellency.

An aircraft comprising:
- a fuel pipe through which fuel flows from a tank that stores the fuel to a fuel supply destination, wherein the fuel tank comprises:
- a hydrophilic surface configured to solidify water thereon;
- and
- a drain port that is fluidly coupled to the fuel tank and configured to discharge the water from the fuel tank;
- an engine as the fuel supply destination;
- a cooling oil pipe wherein cooling oil, used in the engine, flows therethrough;
- and
- a heat transfer member configured to contact a portion of the fuel pipe and a portion of the cooling oil pipe, thereby thermally coupling the fuel pipe and the cooling oil pipe.
