| 20120099962 | Rotor For Turbomachines - A rotor for turbomachines having a plurality of blades, and wherein a damping member, housed inside a respective chamber arranged between the two blades of each pair of adjacent blades of said rotor, is pushed, in use, by the centrifugal force against two surfaces, each of which is carried by a respective blade, which limit the respective chamber in a radially outward direction; the damping member being cup-shaped and being provided with a base wall facing the two surfaces of the relative chamber and having three support bosses on both of said surfaces. | 04-26-2012 |
| 20120087794 | Rotor For Turbomachines With Shrouded Blades - A rotor for turbomachines with shrouded blades comprising a row of a plurality of blades covered by an external ring, coaxial to said row of blades; the external ring being composed of a plurality of sectors, commonly referred to as shrouds, which are adjacent to one another and transversely and circumferentially attached to the end of respective blades; a damping member being arranged so as to straddle a respective pair of adjacent sectors and being pushed, in use, against radially internal surfaces of the sectors of the pair of adjacent sectors. | 04-12-2012 |
| 20120042629 | Method And Plant For The Production Of A Casing For A Solid-Propellant Engine, And Casing Made According To Said Method - A casing of a solid-propellant engine comprising a core and a layer of elastomeric material, set as coating for at least part of the core to provide a thermal protection of the core itself is obtained by: inserting the core in a forming mould so as to make within the mould two annular chambers separated from one another by the core; forming a strand of elastomeric material; obtaining a defined portion of elastomeric material by cutting the strand transversely to size in an external environment; and injecting the cut portion of elastomeric material simultaneously within both of the annular chambers. | 02-23-2012 |
| 20110296840 | GAS TURBINE COMBUSTOR INJECTION ASSEMBLY, AND COMBUSTOR FUEL MIXTURE FEED METHOD - A fuel mixture is fed to a gas turbine combustor by an injection assembly, which has an outer body with combustion-supporting air inlets; a conical tubular portion housed inside the outer body and partly defining an inner conduit and an outer annular conduit; and a first and second feed circuit for feeding liquid fuel to the inner conduit and outer annular conduit respectively; the first circuit having a ring of conduits with respective axes parallel to a generating line of an outer surface of the conical tubular portion. | 12-08-2011 |
| 20110127213 | Process for producing a filter, in particular for a rotary separator - A filter, in particular for a rotary separator, is produced using an energy beam melting process, for example an electron beam, starting from powder made from the same material as a porous filtering portion to be formed, for example from a titanium alloy; on the basis of a three-dimensional model comprising a cell structure defining the porous filtering portion, subsequent layers of powder are applied and locally melted, so as to form successive sections of the porous filtering portion; at the end of the forming process, the residual powder is evacuated from the pores. | 06-02-2011 |
| 20110025067 | MODULAR ELECTROMAGNETIC DEVICE WITH REVERSIBLE GENERATOR-MOTOR OPERATION - A modular electromagnetic device has a stator and a rotor rotating between facing surfaces of the stator and bearing a plurality of magnets distributed with alternate orientations in a substantially ring-shaped pattern, and the stator comprises at least one pair of magnetic yokes symmetrically located at both sides of the rotor. Each yoke has a pair of projecting arms extending towards the magnets and bearing a respective coil for collection of electric power from or supply of electric power to the device. Each yoke is individually mounted on an own support equipped with adjusting units arranged to adjust the yoke position relative to the confronting magnets, and forms, together with its coils, its support, the adjusting units thereof, and sensing and control means controlling the yoke adjustment, an elementary stator cell that can be replicated to form single-phase or multiphase modules. | 02-03-2011 |
| 20110025066 | ELECTROMAGNETIC DEVICE WITH REVERSIBLE GENERATOR-MOTOR OPERATION - An electromagnetic device has a stator and a rotor rotating between facing surfaces of the stator and bearing a plurality of magnets distributed at regular intervals along its periphery. The magnets are so arranged that they form a sequence of alternately opposite poles on the surfaces of the rotor directed towards the stator, and the stator comprises two sets of independently supported magnetic yokes located at both sides of the rotor in front of the magnets. The magnetic yokes have two axially oriented arms, the end surfaces of which, in static conditions of the rotor, at least partly face a pair of successive magnets on a same surface of the rotor. | 02-03-2011 |
| 20100109209 | METHOD FOR THE PRODUCTION OF COMPONENTS MADE OF CERAMIC-MATRIX COMPOSITE MATERIAL - A method for the production of components made of ceramic-matrix composite material, in the fields of aerospace engines and turbines and turbine systems and plants; according to the method, a preform of ceramic fibres is shaped and set in a draining mould, for example made of plaster; the fibres of the preform are impregnated with a suspension of ceramic powders, the liquid of which is drained by capillarity from the draining mould; simultaneously to draining, a suspension of ceramic powders is infiltrated between the fibres of the preform so as to fill the empty space left by the drained liquid; at the end of the steps of draining/infiltration a body is obtained with a solidified or compacted porous matrix, which is removed from the draining mould and is sintered. | 05-06-2010 |
| 20090304965 | METHOD AND PLANT FOR THE PRODUCTION OF A CASING FOR A SOLID-PROPELLANT ENGINE, AND CASING MADE ACCORDING TO SAID METHOD - A casing of a solid-propellant engine comprising a core and a layer of elastomeric material, set as coating for at least part of the core to provide a thermal protection of the core itself is obtained by: inserting the core in a forming mould so as to make within the mould two annular chambers separated from one another by the core; forming a strand of elastomeric material; obtaining a defined portion of elastomeric material by cutting the strand transversely to size in an external environment; and injecting the cut portion of elastomeric material simultaneously within both of the annular chambers. | 12-10-2009 |
| 20090123646 | METHOD AND PLANT FOR SIMULTANEOUSLY COATING INTERNAL AND EXTERNAL SURFACES OF METAL ELEMENTS, IN PARTICULAR BLADES FOR TURBINES - Method and plant for simultaneously coating internal and external surfaces of a metal item, whereby a gaseous mixture comprising a coating agent is fed towards the external surfaces of the metal item to be coated and towards each of the inlets of the internal passages or pipes of said metal item; simultaneously, in a continuous or pulsating way, a gaseous flow different from the entraining gaseous mixture being introduced into the internal passages to generate a current for entraining the gaseous mixture within the internal passages themselves. | 05-14-2009 |
