Patent number: 10444089Abstract: A carbon fiber element comprising a carbon fiber to which a coating is applied that reduces its thermal coefficient of resistivity (TCR) can be included in a fiber reinforced structural component to improve sensing of strain therein by reducing errors arising from temperature variations. A method thereof includes providing, embedded within the structural component, at least one carbon fiber extending across a principle plane of the structural component, the carbon fiber being uniformly coated along its entire length with an electrically conductive material, the coating having a resistance that is equal to the carbon fiber and a TCR that is equal but opposite to the carbon fiber. The strain in the structural component is then determined by measuring changes in the electrical resistance of the carbon fiber element.Type: GrantFiled: January 30, 2015Date of Patent: October 15, 2019Assignee: BAE Systems plcInventors: Martyn John Hucker, David William Gough

Patent number: 8796553Abstract: Composite structural components are disclosed that include electrically conducting fibers providing multiple signal or paths to electrical components disposed on or adjacent the material. The signal paths may therefore be embedded in the structural component as an intrinsic reinforcing element. Also disclosed are materials for making up the structure and fabrics and methods for the production thereof.Type: GrantFiled: July 7, 2009Date of Patent: August 5, 2014Assignee: BAE Systems PLCInventors: Martyn John Hucker, Sajad Haq, Michael Dunleavy, David William Gough, Jason Karl Rew, Philip Lawrence Webberley

Patent number: 8534133Abstract: A structural health monitoring arrangement includes a component formed of fiber reinforced composite material with a plurality of electrical conducting fibers intrinsic to the composite defining electrical paths that run through the composite. The paths act as sensing paths running through the material and a detector watches for changes in electrical property indicative of a structural event. The paths may be configured as an open or a closed node grid whose electrical continuity is monitored directly or indirectly. Alternatively they may be fibers having a piezoresistive property and the changes in resistance may be monitored.Type: GrantFiled: July 7, 2009Date of Patent: September 17, 2013Assignee: BAE Systems PLCInventors: Martyn John Hucker, Sajad Haq, Michael Dunleavy, David William Gough, Jason Karl Rew, Philip Lawrence Webberley

Patent number: 8322206Abstract: In order to discriminate between laminar flow and turbulent flow states, and to provide an indication, e.g. to a pilot of an aircraft of air flow over an aircraft wing, a sensor mounted on the wing provides an analogue signal of airflow, and an intermittency value of the analogue signal is derived in analogue circuitry including an AC coupling of the signal to an integrator for integrating the signal for a preset time. The integrated value is compared with a threshold value to indicate whether the intermittency represents quiet laminar flow or noisy turbulent flow.Type: GrantFiled: September 8, 2008Date of Patent: December 4, 2012Assignee: Bae Systems PLCInventors: Martyn John Hucker, Clyde Warsop, Graham Andrew Johnson, David William Gough

Patent number: 8061194Abstract: To provide an indication of whether airflow is separated, as opposed to other states of flow, over a surface, two or more adjacent sensors at a location on the surface each produce an analogue signal representative of airflow. The analogue signals are correlated with each other, and the degree of correlation indicates whether the airflow is in a separated state. The correlation may be carried out by comparing processed values of the analogue signals, and thresholding the comparison result.Type: GrantFiled: September 10, 2008Date of Patent: November 22, 2011Assignee: Bae Systems PLCInventors: David William Gough, Graham Andrew Johnson, Clyde Warsop, Martyn John Hucker
