Abstract: A method of determining the position of a defect (32) within a fibre composite article (10) comprising a plurality of electrically conductive fibres (14) embedded within a non-conductive matrix (15). The method comprises providing an array of spaced electrical contacts (12a-k) in electrical contact with fibres (14) of the article (10); conducting an electrical current between two or more spaced electrical contacts (12a-k) of the array to determine a measured electrical profile of the article comprising measurements of at least one of electrical resistance, inductance, capacitance and self-resonant frequency of the article; and comparing the electrical profile with a nominal electrical profile representative of an undamaged article to determine the presence of a defect within the article.To be accompanied when published by FIG. 5

Abstract: A robot for cleaning submersed marine structures is provided. The robot has a drive system for traversing the robot over the submersed structure. The robot further has an attachment system for attaching the robot to the submersed structure. The robot further has a cleaning arrangement for removing biofouling from the submersed structure as the robot is traversed thereover. The robot further has one or more flexible detector strips which contact the submersed structure as the robot is traversed thereover. The strips have a plurality of electrodes and are formed from electroactive polymer material which produces electrical signals in the electrodes on deflection of the strips. The signals are indicative of the surface roughness of the submersed structure.

Abstract: An apparatus for metallurgical heat-treatment includes a solid-oxide electrolyser, a furnace and a heat-exchanger. The electrolyser is arranged to electrolyse water and provide resulting hydrogen to the furnace. A first portion of the hydrogen from the electrolyser is combusted in a combustor to heat the furnace. A second portion provides a treatment atmosphere including hydrogen for the heat-treatment of a metal or metal alloy object. Water vapour output by the combustor is provided to the heat-exchanger which transfers heat within the water vapour to the solid-oxide electrolyser to improve or maintain its efficiency. In contrast to apparatus of the prior art, the apparatus does not produce carbon dioxide at the point of use. By applying waste heat, carried by the water vapour output from the combustor, to the electrolyser, the power consumption of the electrolyser is reduced for a given rate of electrolysis.

Abstract: An aircraft comprises a hydrogen-fuelled propulsion system, a plurality of like generally cylindrical hydrogen storage tanks and a conveying system arranged to convey hydrogen from the hydrogen storage tanks to the hydrogen-fuelled propulsion system. The aircraft further comprises a fuselage having a cargo bay (502) including one or more (510A-G) of the plurality of hydrogen storage tanks, the longitudinal axes (511A-G) of the one or more hydrogen storage tanks within the cargo bay extending parallel to the longitudinal axis (501) of the fuselage and lying in one or more planes (595, 597) extending across the width dimension of the cargo bay. The hydrogen storage tanks within the cargo bay have a common aspect ratio R in the range 4.2≤R≤25.7, allowing the volume of space with the cargo bay occupied by stored hydrogen to be maximised or approximately maximised.

Abstract: A battery or fuel cell module comprising a plurality of battery cells or fuel cells and metal foam bus bars that electrically connect together at least some of the battery cells or fuel cells is described. The battery or fuel cell module may further include a cooling system arranged to provide a flow of cooling fluid through the metal foam bus bars to remove heat from the bus bars. In some examples, the cooling system comprises one or more forced air devices. In other examples, the metal foam bus bars are encased in a fluid-impermeable skin so that the bus bars form fluid-tight pipes with a metal foam interior, and the cooling system is arranged to provide the flow of cooling fluid through the metal foam interior of the fluid-tight pipes.

Abstract: A composite gas storage tank includes a composite wall defining a main storage volume and a hollow conduit portion communicating with and extending away from the main storage volume. A hollow coupling element has a length portion which is partially embedded within and extends substantially parallel to the hollow conduit portion of the composite wall. The hollow conduit portion and the coupling element provide communication between the main storage volume and the tank exterior. A leakage path around the hollow coupling element is significantly longer than those of tanks of the prior art and reduces the rate at which hydrogen leaks from the tank. A carbon fibre filament winding extends over the length of the hollow conduit portion and provides a radially inwardly-directed force biasing the carbon fibre material of the hollow conduit portion into contact with the coupling element, further reducing the leakage rate on the leakage path.
