| 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 |
| 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 |

| 20090217498 | METHOD FOR CONTROLLING THE LOCAL CHARACTERISTICS OF A NON-WOVEN TEXTILE AND RELATED INSTALLATION - A crosslapper receives a card web and folds it into a lap intended to be needle-punched or consolidated by other means. The web comprises zones which are more condensed, having a spectrum of orientation of fibres with a component parallel to the width of the web, alternating with less condensed zones having a longitudinal unidirectional spectrum of orientations. The zones which are less condensed are used to form the edge zones of the lap. The result is that the lap has different respective spectra of orientation which pre-compensate for the unwanted changes produced by the needle-punching or other consolidation which follows. A needle-punched lap is obtained having a uniform MD/CD ratio (relationship between longitudinal and respectively transverse tensile strengths) or having a sought profile of the MD/CD ratio across the width of the lap. | 09-03-2009 |
