    Abstract: A fuel injector provided for gas turbine engine has a nozzle including pilot fuel and mains fuel discharge orifice's for respectively spraying pilot and mains fuel flows into a combustor of the engine. The injector further has a feed arm extending to the nozzle for feeding fuel to the pilot and mains discharge orifices from pilot and mains supplies respectively. The nozzle and the feed arm contain one or more pilot passages for flow of the pilot fuel flow from the pilot supply to the pilot discharge orifice and one or more mains passages for flow of the mains fuel flow from the mains supply to the mains discharge orifice. The nozzle and the feed arm contain a plurality of the pilot passages and/or a plurality of the mains passages. The pilot and the mains passages intertwine repeatedly, and are both smoothly curved as they intertwine around each other.

    Abstract: A method for the manufacture of a component of defined geometry from two or more materials using a powder bed ALM process includes providing a bed of a first powdered material, selectively fusing portions of the first powdered material to build up a first three dimensional portion of the component geometry and fusing a powder containment bund from the first material to contain unfused first powdered material. A bed of a second powdered material is deposited onto the powder containment bund and selectively fused to build up a second three dimensional portion of the component geometry. Unfused first powdered material can subsequently be removed from a first side of the bund and unfused second powder from a second side of the bund. Remaining parts of the bund which do not form part of the defined geometry of the component can be removed to provide the net shape component.

    IPC: F01D25/24

    Abstract: The manufacture of a casing which has a boss includes providing two canister portions a first defining an outer wall geometry of a casing including a boss and a second defining an inner wall geometry of the casing. The casing is made using known PHIP methods. The second canister portion includes an array of holes or recesses which, when the canister portions are aligned, face a recess on the first canister portion which defines the boss such that in the nett shape COS an array of pedestals is provided aligned with the boss. The dimension from an exposed end of a pedestal to an exposed surface of the boss is sufficient to receive a bolt thread of the minimum length required to secure a component to the boss.

    Abstract translation: 具有凸台的壳体的制造包括提供两个罐部分，第一部分限定外壳的外壁几何形状，所述外壳包括凸台和限定外壳的内壁几何形状的外壳。 外壳采用已知的PHIP方法制成。 第二罐部分包括孔或凹槽的阵列，当罐部分对齐时，它们面向限定凸台的第一罐部分上的凹部，使得在网状形状COS中，提供与凸台对准的基座阵列。 从基座的露出端到凸台的暴露表面的尺寸足以接收将部件固定到凸台所需的最小长度的螺栓螺纹。

    Abstract: An energy source for an additive manufacturing arrangement comprises a workpiece and a powder delivery device. The energy source is characterised in that it comprises a plurality of discrete energy sources. The plurality of discrete energy sources may be coordinated in use to deliver energy simultaneously to a plurality of regions of the workpiece in a matrix form.
