摘要： 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.

摘要： 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.

摘要： A method and apparatus are provided for treating flammable materials, fuels for example, by irradiation of the materials with ultra-violet radiation. In one embodiment, the apparatus (120) suited for connection to a fuel line comprises a body (94) with centrally-formed duct (95) and UV light sources (100, 102) mounted outside of the duct at upper 96and lower (97) sides. It is to be appreciated that the invention has utility for many different fuel system applications, for example in aircraft, boats and in other motive vehicles. Further, the apparatus (120) can be conveniently mounted, if desired, on different fuel platforms including on bowsers.

摘要： 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.
