  • Publication number: 20200411750
    Abstract: A method for producing an ultrasonic transducer or ultrasonic transducer array, the method comprising providing or depositing a layer of piezoelectric material on a substrate. The piezoelectric material is a doped, co-deposited or alloyed piezoelectric material. The piezoelectric material comprises: a doped, co-deposited or alloyed metal oxide or metal nitride, the metal oxide or metal nitride being doped, co-deposited or alloyed with vanadium or a compound thereof; or zinc oxide doped, co-deposited or alloyed with a transition metal or a compound thereof. Optionally, the deposition of the layer of piezoelectric material is by sputter coating, e.g. using a sputtering target that comprises a doped or alloyed piezoelectric material. In examples, the layer of piezoelectric material is deposited onto the substrate using high power impulse magnetron sputtering (HIPIMS). Further enhancement may be obtained using substrate biasing (e.g. DC and/or RF) during deposition of the layer of piezoelectric material.

  • Publication number: 20200380180
    Abstract: A turbine with multiple gas inlets is designed by a process of, for a given engine, obtaining time series data characterizing the power bias of the engine, obtaining an isentropic power associated with each data point of the time series, and using the isentropic powers to obtain a design point. The turbine is then designed based on the design point, such as by optimising one or more design parameters of the turbine based on the design point.

  • Publication number: 20200300158
    Abstract: A turbine comprises a housing defining a turbine chamber with a turbine wheel supported for rotation about an axis. The housing further defines first and second inlet volutes which each spiral radially inwards and extend from a respective inlet to adjoin the turbine chamber and a volute tongue for each inlet volute. The tongue of the first volute radially separating a downstream portion of the first volute adjacent the chamber from an upstream portion of the first volute adjacent said inlet of the first volute, and the tongue of the second volute radially separating a downstream portion of the second volute adjacent the chamber from an upstream portion of the second volute adjacent said inlet of the second volute. The tongues having a turbine scroll tongue overlap which is substantially zero or positive; and the first volute tongue is angularly spaced about the axis from the second volute tongue.

  • Publication number: 20200300160
    Abstract: A turbine comprises a turbine wheel for rotation within a turbine housing, the turbine housing including at least one volute arranged to deliver a fluid to the turbine wheel via the turbine nozzle. A method for determining a width of a turbine nozzle for the turbine, comprises selecting from a relationship between a turbine stage efficiency and an effective nozzle area, at least one target effective nozzle area. As used here, the effective nozzle area is dependent on both the width of the turbine nozzle and a whirl angle induced by the at least one volute. The method further comprises determining, in dependence on the whirl angle, the width of the turbine nozzle as a width that will achieve the at least one target effective nozzle area.

  • Publication number: 20190316434
    Abstract: A downhole tool having a mandrel, and a bottom slip disposed around the mandrel. The bottom slip includes a circular body having a one-piece configuration characterized by a plurality of slip segments by at least partial material connectivity therearound. The bottom slip is made of a filament wound composite material, which means the bottom slip has a plurality of layers joined by respective interface layers. An outer slip surface of at least one of the plurality of slip segments is defined in cross-section by a plane P that intersects a longitudinal axis of the downhole tool at an angle a1 in a range of 10 degrees to 20 degrees when the bottom slip is in an unset position.

  • Publication number: 20190302305
    Abstract: Non-visible objects which differ in their physical properties from their surroundings by association with a variable strength magnetic field may be detected by a suitable array of sensors which can be moved relative to the object in question. By analyzing the signals from the plurality of the sensors in the array, the position of the object can be deduced relative to the array and the array moved to enable a machining guide thereon to be aligned with the non-visible object. The system is of particular value in locating apertures in wing spars when attempting to fix the skin of the wing on to them where it is important to be able to locate the correct point at which to drill a hole through the skin to coincide with the hole in the spar. By defining a magnetic field in the vicinity of the hole to identify the hole magnetically and using an array of magnetic field sensors in a base with an aperture, it is possible to shift the array so that the aperture is precisely aligned with the non-visible hole.
