Patent number: 10189576Abstract: A liquid storage tank, for example an aircraft fuel tank, having a tank wall enclosing a liquid storage space, and a tie assembly located at least partially within the liquid storage space. The tie assembly includes an elongate member, for example a wire or cable, and a plurality of attachment devices fixed to an inner surface of the tank wall. The elongate member includes a plurality of spaced part points along its length, each of the spaced apart points being fixed to a respective attachment device such that the tie assembly resists outward deformation of the tank wall.Type: GrantFiled: May 6, 2015Date of Patent: January 29, 2019Assignee: BAE SYSTEMS PLCInventors: Nicholas John Martindale, Nicholas Park, Simon Anthony Jenkins, Andrew James Irwin, Christopher Steven Bingham, Chrisostomos Angelis Constantinou

Patent number: 9944403Abstract: A liquid storage system comprising: a tank for containing a liquid, the tank enclosing a liquid storage space; multiple layers of a fabric material; and attachment means attaching the multiple layers of the fabric material to an internal surface of the tank. The attachment means may comprise a non-permeable envelope attached to the internal surface of the tank. The multiple layers of the fabric material may be enclosed in the envelope such that the multiple layers of a fabric are isolated from a fluid in the tank. The envelope may contain a fluid (e.g. air) in addition to the multiple layers of the fabric material.Type: GrantFiled: May 6, 2015Date of Patent: April 17, 2018Assignee: BAE Systems plcInventors: Nicholas Park, Simon Anthony Jenkins, Andrew James Irwin

Patent number: 9745076Abstract: A baffle system includes a baffle (40) located in a tank (16) for containing liquid (e.g. an aircraft fuel tank). The baffle (40) is a tubular member through which a liquid may flow. The baffle (40) comprises: a first tubular portion (42) providing a tubular outer wall, and a second tubular portion (44) located within the first tubular portion (42) and providing a tubular inner wall. The first and second tubular portions (42, 44) are substantially parallel. The first and second tubular portions (42, 44) are spaced apart to define a chamber (46) therebetween. The baffle (42, 44) further comprises radial side walls between the first and second tubular portions (42, 44) such that the chamber (46) is a sealed chamber. The chamber (46) may be filled with a compressible gas or gaseous mixture.Type: GrantFiled: May 6, 2015Date of Patent: August 29, 2017Assignee: BAE Systems plcInventors: Christopher Steven Bingham, Andrew James Irwin

Publication number: 20170050741Abstract: Disclosed is a baffle (40) for locating in a tank (16) for containing liquid. The baffle (40) comprises: a baffle wall enclosing an internal cavity (48); and one or more openings (50) in the baffle wall configured to permit the flow of a fluid between the internal cavity (48) of the baffle (40) and a volume external to the baffle wall. The baffle wall comprises an outer wall (42), and an inner wall (44) located within the outer wall (42). The outer and inner walls (42, 44) each comprise one or more openings. Each of the openings in the outer wall (42) is attached to a respective opening in the inner wall (44) via a respective opening side wall. The outer and inner walls (42, 44) are spaced apart to define therebetween a chamber (46).Type: ApplicationFiled: May 6, 2015Publication date: February 23, 2017Inventors: Christopher Steven Bingham, Andrew James Irwin, David Peter Pearson
