摘要： A rotor (20) for a compressor, in particular in a gas turbine, has a number of rotor blades (25) which are arranged around the rotation axis of the rotor (20) in the form of a rim and are each held in a circumferential recess (21) on the rotor (20) by a blade root (26), with the blade root (26) having a widening lower part (27) which engages behind two shoulders (24) that are formed on the side walls of the recess (21). In such a rotor, the life is lengthened in that the recess depth (T) of the recess (21) is substantially greater than a minimum recess depth (Tmin) which results in the rotor (20) having sufficient strength in the area of the blade attachment for starting, based on the predetermined material characteristics of the rotor (20) and the operating conditions of the compressor.

摘要： A method of manufacturing a regeneratively cooled rocket combustion chamber which includes a thrust nozzle portion connected to a combustion chamber portion and which is constructed with cooling channels which extend in the longitudinal direction between an inner shell or wall having a smooth interior surface and an outer shell or wall and which are laterally bounded by radially extending webs, comprises forming the inner shell along with the cooling channel webs by electrodepositing metal on an electroplating core which is made up of chemically dissolvable material and has its outside contour conformable to the inside contour of the inner wall of the combustion chamber which is provided with radially extending projections forming mold blades for the webs defining the lateral boundaries of the cooling channels. Thereafter, the cooling channels are filled with a multiple electrically well-conducting filling material up to the level of the outer ends of the webs after these outer ends have been finish turned. A metal layer is then electrodeposited around the complete periphery of the web end faces and over the periphery of the cooling channels to form the outer shell or wall. The filling material is then melted out of the cooling channels and the electroplating core is hollowed out except for some millimeters of residual wall thickness and the remnant of the core is dissolved along with the radial projections to form the slots between the cooling channel webs which open into the center of the combustion chamber. The entire electrodeposited rocket combustion chamber is then engaged over the finishing mandrel and while it is on the mandrel, the cooling channels are deformed by applying pressure from inside the channels to close the slot which extends between the webs. When the thrust nozzle portion is formed integrally with the combustion chamber, the mandrel is transversely parted in the nozzle throat plane to permit insertion during the deforming of the cooling channels.

摘要： A method for the manufacture of a component having an internal cavity and an array of pedestals extending into the cavity includes; defining external and core geometries of the component; using a powder-bed additive layer manufacturing method, building the component from a plurality of layers laid on a first-plane; and removing excess powder from the core in a first powder extraction direction along the first-plane. The core geometry is adapted for improved powder removal; including a main core passage, an array of pedestals extending into the passage and passage wall extending from the first-plane, one or more pedestals coinciding with the passage wall, having a cross-section in a plane parallel to the first-plane which is altered with respect to the cross-section of non-coinciding pedestals to extend a face of the pedestal which faces away from the powder extraction direction to intersect the passage wall at an obtuse angle.
