| 20090194485 | DETECTING THE CLOGGING OF A FLUID FILTER - The invention relates to the field of fluid filters. It provides a method of detecting clogging of a fluid filter, which method comprises measuring, at successive sampling instants, the pressure difference ΔP from upstream to downstream across the filter, and then calculating the first time derivative {ΔP}′ of the pressure difference ΔP at different instants, and then sending a clogging signal S | 08-06-2009 |
| 20100000223 | METHOD OF TAKING OFF AUXILIARY POWER FROM AN AIRPLANE TURBOJET, AND A TURBOJET FITTED TO IMPLEMENT SUCH A METHOD - Producing the electrical power need for equipment on board an airplane. Auxiliary power is taken off by means of a shaft driven by the high pressure turbine and, when idling, the efficiency of the low pressure turbine is degraded so as to enable the high pressure turbine to operate at a speed that is sufficient for delivering the required auxiliary power. | 01-07-2010 |

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 |
| 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 |
| 20110229310 | SYSTEM FOR CONTROLLING VARIABLE GEOMETRY EQUIPMENT OF A GAS TURBINE ENGINE PARTICULARLY COMPRISING A BARREL LINK - A system for controlling at least two variable geometry apparatuses of a gas turbine engine that includes at least a first body and a second body, the first apparatus including a stator blade stage with a variable setting angle of a compressor of the first body capable of switching between a closed position in an idle mode and an open position in a high-speed mode, and the second apparatus including at least one discharge valve of a compressor of the second body capable of switching between an open position in an idle mode and a closed position in a high-speed mode. The system further includes an actuator for actuating the two apparatuses. | 09-22-2011 |
