AIRCRAFT FUEL SYSTEM WITH CYCLONIC SEPARATOR

摘要

An aircraft fuel system comprising: a fuel tank (20); and a cyclonic separator (1). The cyclonic separator comprises: a separation chamber; an inlet (2) in fluid communication with the fuel tank (20) and the separation chamber; a fuel outlet (4) in fluid communication with the separation chamber; and a water outlet (3). The cyclonic separator is adapted to discharge water from the water outlet (3) and relatively less dense liquid fuel from the fuel outlet (4), and wherein the cyclonic separator (1) further comprises a permeation member (22) formed from a water-permeable material which enables water in the separation chamber to flow through the water-permeable material and out of the water outlet (3), but substantially prevents liquid fuel in the separation chamber from doing so.
