20130078585 | METHOD FOR DETERMINING A ZONE WHERE A COMBUSTION CHAMBER IGNITION PLUG IS TO BE POSITIONED, AND ASSOCIATED COMBUSTION CHAMBER - A method for determining an optimum positioning zone of an ignition plug fitted with a semiconductor element in a combustion chamber, where the method includes: | 03-28-2013 |
20130125558 | PREHEATING A SPARK PLUG - A method of igniting a turbine engine using a spark plug including a first electrode, a second electrode, and a semiconductor body between the first electrode and the second electrode, the semiconductor body having an exposed surface, the ignition method including: generating a spark adjacent to the exposed surface by applying a voltage difference greater than a first predetermined threshold between the first electrode and the second electrode; and prior to generating a spark, a preheating applying a voltage difference less than a second predetermined threshold between the first electrode and the second electrode, the second predetermined threshold being less than the first predetermined threshold. | 05-23-2013 |
20140178202 | TURBINE ENGINE IMPELLER - A turbine engine rotor wheel including a disk including at least one slot formed in its outer periphery for mounting roots of blades, a presser being mounted between each blade root and a bottom of the slot. The presser is bistable in position and is capable of occupying a first stable position for assembly and disassembly in which it does not exert a force on the blade root, and a second stable position in which it exerts a radial force on the blade root to hold the blade stationary and to stabilize the blade in a final position. | 06-26-2014 |

20140161617 | BLADED ROTOR WHEEL FOR A TURBINE ENGINE - A bladed rotor wheel for a turbine engine, the rotor wheel including a disk including, formed in its outer periphery, at least one slot for mounting the roots of blades, and a spacer mounted between each blade root and a bottom of the slot. The spacer includes at least one member of type that is bistable in position and that can occupy a first stable position for assembly or disassembly in which the member does not exert force on the blade root, and a second stable position in which the bistable member exerts a radial force on the blade root. The spacer also includes at least one resilient damper member mounted between the bottom of the slot and the blade root. | 06-12-2014 |
