| 20100080684 | SYSTEM FOR CONTROLLING VARIABLE-GEOMETRY EQUIPMENTS OF A TURBOMACHINE, PARTICULARLY BY ARTICULATED BELLCRANKS - A system for controlling at least two variable-geometry equipments ( | 04-01-2010 |
| 20100158662 | SYSTEM FOR CONTROLLING AT LEAST TWO VARIABLE-GEOMETRY EQUIPMENTS OF A GAS TURBINE ENGINE, PARTICULARLY BY RACK - The invention relates to a system for controlling at least two variable-geometry equipments of a gas turbine engine. The engine comprises at least a first core rotating at a first speed and a second core rotating at a second speed, the first equipment ( | 06-24-2010 |
| 20100158663 | SYSTEM FOR CONTROLLING AT LEAST TWO VARIABLE-GEOMETRY EQUIPMENTS OF A GAS TURBINE ENGINE, PARTICULARLY BY CAM MECHANISM - The invention relates to a system for controlling at least two variable-geometry equipments of a gas turbine engine. The engine comprises at least a first core rotating at a first speed and a second core rotating at a second speed, the first equipment ( | 06-24-2010 |
| 20110150567 | MECHANICAL DRIVE DEVICE FOR DRIVING THE HIGH PRESSURE SUB ASSEMBLYSUB ASSEMBLY OF AN AIRPLANE ENGINE - Providing manual mechanical drive to the high pressure sub assembly of a turbojet, in particular during endoscopic inspection of the high pressure turbine. According to the invention, a coupling element suitable for coupling with an external actuator such as a crank handle is fitted on the axis of a specific alternator that is normally driven mechanically via the high pressure sub assembly, thereby providing a coupling suitable for driving said high pressure sub assembly. | 06-23-2011 |
| 20110182716 | SYSTEM FOR CONTROLLING VARIABLE GEOMETRY APPARATUSES IN A TURBINE ENGINE - A control system for controlling at least two variable-geometry devices of a turbomachine, and a turbomachine including such a control system, the system including an actuator that actuates both devices; one of the devices including at least one stage of variable-pitch stator vanes, and the other device being an air-bleed valve for a turbomachine body. The system is configured to control progression opening of the vane stage and progressive closing of the air-bleed valve as an actuation parameter of the actuator increases. As a result, the control system serves advantageously to control two devices using a single control system. | 07-28-2011 |
| 20110184573 | SYSTEM FOR CONTROLLING VARIABLE GEOMETRY EQUIPMENT FOR A TURBINE ENGINE, ESPECIALLY BY BELLCRANKS - A system for controlling at least two sets of variable geometry equipment of a turbine engine. The turbine engine includes at least one first body and a second body, the first set of equipment being a stage of variable stator vanes of a compressor of the first body moving between a closed position during idling and an open position at high speed, and the second set of equipment being at least one bleed valve of a compressor of the second body moving between an open position during idling and a closed position at high speed. The actuator drives the second set of equipment by an actuating part that is actuated over part of the course of the actuator and idle on an abutment over the rest of the course, and by a sliding joining element providing a backlash in the actuation of the second set of equipment. | 07-28-2011 |
| 20110190950 | SYSTEM FOR CONTROLLING VARIABLE GEOMETRY EQUIPMENT OF A GAS TURBINE ENGINE ESPECIALLY COMPRISING A GUIDING TRACK CONNECTION - A system for controlling at least two sets of variable geometry equipment of a gas turbine engine including at least one first body and a second body, the first set of equipment being a stage of variable stator vanes of a compressor of the first body moving between a closed position during idling and an open position at high speed, and the second set of equipment being at least one bleed valve of a compressor of the second body moving between an open position during idling and a closed position at high speed. An actuator actuates the two sets of equipment. | 08-04-2011 |
