摘要： A method for casting a diafram having inner and outer rings with preformed vanes circumferentially spaced therebetween is disclosed. A digital representation of a sand core is created. Based on this digital representation, a sand core is produced by bonding together successive layers of sand with droplets of a binder material using a binder printhead having nozzles for supplying jets of binder material droplets. A plurality of vanes is inserted into the cavities of the sand core. The sand core is then placed into a casting mold and filled with liquid metal. After the liquid metal has solidified and cooled, the sand core and any remaining sand is removed from the cast diafram.

摘要： A direct acting hydraulic voting trip block defines three separate paths between an inlet and an outlet port. Each path is intersected by a valve cylinder. Valve pistons in each valve cylinder are configured, in the activated position, to block two of thee different paths. As long as at least two of the pistons are in the activated position, communication between the inlet and outlet ports is prevented, thus providing a hydraulic majority voting logic valve system.

摘要： A passive dynamic inertial rotor balance system including a plurality of balancing members fitted onto a rotor shaft at locations of predicted maximum shaft modal deflection. Each of the balancing members has at least one chamber and located within the at least one chamber is a plurality of movable weights and a viscous fluid. As the shaft accelerates toward an unbalance point, the weights move within the at least one chamber to a location which is opposite from the unbalance point. The viscous fluid provides damping for the movable weights to prevent excess movement within the chamber and to provide lubrication thereof. A system for self-correcting an unbalance of a turbomachinery rotor during rotation of the rotor and a method for balancing a rotor in a turbomachinery is also provided.

摘要： A magnet cradle for supporting a permanent magnet in an overhung recessed slot on the surface of a permanent magnet rotor having an axis of rotation. The cradle is non-magnetic and comprises a top and bottom wall abutting the permanent magnet. The cradle is sized to hold the permanent magnet within the overhung slots. Axial end walls generally perpendicular to the axis of rotation have circumferential edges configured to directly abut overhung portions of the slots. The total axial length of the top and bottom walls of the cradles in the axial direction are greater that the total axial length of the magnet, thereby permitting a magnet to fit between the axial end walls of the cradle without the cradle in the magnetic flux path of the magnet.
