WATER REMOVAL SYSTEM Russian patent published in 2012 - IPC B64D37/34 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly, to fuel feed and water removal pumps, to method and system for water removal from fuels tanks. Proposed system comprises first and second fuel pumps, each being made to bleed fuel from one fuel tank to pump it over to engine. Besides, said system comprises water exhaust line communicating fuel tank water inlet with first fuel pump. Note here that first fuel pump serves to pump fuel to engine with higher fuel consumption than delivery of first pump unless the latter fails. Water removal method consists in feeding water to first fuel pump via water pumping line and pumping fuel to engine by first fuel pump with higher delivery compared with that of second pump. In compliance with another version, water removal from fuel tank bottom settler is carried out in taking off or in climb, and further water feed in aircraft engine. Water removal system arranged in aircraft fuel tank may discharge from one or more openings for water inlet and feed into aircraft engine. Fuel tank bottom section has point for water accumulation in take-off or climb.

EFFECT: higher efficiency.
