20100257867 | MONITORING OF A HIGH-PRESSURE PUMP IN A TURBINE ENGINE FUEL SUPPLY CIRCUIT - A device and method for monitoring a high-pressure pump in a turbomachine fuel supply circuit by detecting opening of a pressurizing and shut-off valve mounted on an outlet side of a fuel flow regulating valve, by measuring rotational speed of the turbomachine corresponding to the opening of the pressurizing and cut-off valve, and by monitoring change in a value of the rotational speed to propose replacement of the high-pressure pump when the measure value rotational speed reaches a predetermined threshold. | 10-14-2010 |
20110234236 | METHOD AND A DEVICE FOR DETECTING AN ELECTRICAL FAILURE AFFECTING AN ELECTRIC CONTROL SYSTEM OF A HYDRAULIC ACTUATOR OF VARIABLE GEOMETRIES OF AN AEROENGINE - After the control system has been started, which system has two control paths that are used as alternatives for delivering a control electric current to an electrohydraulic member for transforming said current into hydraulic power that is delivered to the actuator, and before powering a starter-generator of the engine, the detection method comprises implementing the following steps for each of the control paths in succession: | 09-29-2011 |
20120032809 | METHOD OF DETECTING AN ICING STATE OR A NEED FOR MAINTENANCE IN A TURBOMACHINE FUEL CIRCUIT - Detecting a state of icing in a turbomachine fuel circuit includes reading information representative of a first temperature T | 02-09-2012 |
20120085101 | METHOD OF TESTING A SYSTEM FOR PROTECTING A TURBOMACHINE AGAINST OVERSPEED WHILE STARTING - In a testing overspeed protection system: a) on receiving an order to start a turbomachine, an electronic regulation system (ERS) of the turbomachine sends an order to a control circuit of a fuel cutoff member to close the fuel cutoff member or to keep it in the closed position; b) the closed state of the FCM is verified on the basis of information transmitted to the ERS and representative of the position of the FCM; c) if the result of the verification in b) is positive, the ERS sends an order to the FCM control circuit to authorize opening of the FCM and enable the starting procedure to continue; and d) if the result of the verification in b) is negative, the ERS issues fault information concerning the overspeed protection system. | 04-12-2012 |
20120272710 | METHOD AND A DEVICE FOR REAL TIME MONITORING OF A SYSTEM FOR MEASURING A FUEL FLOW RATE - A device and method of monitoring the measurement of a fuel flow rate fed to an airplane engine includes delivering the measurement from a mass flowmeter. The monitoring also includes evaluating whether at least the following conditions are satisfied: a signal delivered by the flowmeter is less than a given value; and the engine is running on its own. The measurement is invalidated if these conditions are satisfied simultaneously. | 11-01-2012 |
20130088249 | METHOD OF DETECTING A FAULT WITH THE MEANS FOR DE-ICING A PROBE FOR MEASURING A PHYSICAL PARAMETER - A method of detecting a fault in a de-icer probe for measuring a physical parameter on an airplane engine, the method including: prior to starting an engine, measuring a first value of the physical parameter with help of the probe; activating the probe de-icer; at an end of a determined duration from a start of de-icing, measuring a second value of the parameter with help of the probe; and comparing the first and second values and generating a fault signal if the difference between the first and second values is less than a determined threshold. | 04-11-2013 |

20110186003 | METHOD FOR PRODUCING A PISTON FOR AN INTERNAL COMBUSTION ENGINE AND PISTON FOR AN INTERNAL COMBUSTION ENGINE - In a method for producing a piston for an internal combustion engine, at least the region of the upper annular groove is at least partially recessed, an adhesion promoter layer containing aluminium is then applied, a wear-resistant layer is thermally sprayed onto said adhesion promoter layer and at least the upper annular groove is at least partially formed in said layers. The invention also relates to a piston for an internal combustion engine that comprises a base material, an adhesion promoter layer that contains aluminium and is applied to at least some regions of said material and a wear-resistant layer that is thermally sprayed onto said adhesion promoter layer. At least the upper annular groove is at lest partially formed in said layers. | 08-04-2011 |
20120103298 | METHOD AND DEVICE FOR PRODUCING A PISTON FRO AN INTERNAL COMBUSTION ENGINE AND PISTON FOR INTERNAL COMBUSTION ENGINE - The invention relates to a method for producing a piston for an internal combustion engine, wherein a section which in the finished piston has a cooling duct (14) and a piston ring groove is recessed at first, the later cooling duct is then covered, and finally material for accommodating the piston ring is applied, and which is characterized in that the later cooling duct is covered by a wire material which is provided in a length, greater than necessary for one single piston. A device for producing a piston for an internal combustion engine with an at first recessed section that in the finished piston has a cooling duct (14) and a piston ring groove, has a device for attaching a cover on the cooling duct and a device for providing wire material having a length greater than necessary for one single piston. A piston for an internal combustion engine has a cooling duct (14) and a reinforcement material for accommodating a piston ring as well as a cover material between the cooling duct (14) and the reinforcement material, wherein the cover material is made of wire material continuously unwinding from a roll. | 05-03-2012 |

20150153740 | SAFE EMERGENCY LANDING OF A UAV - Method for autonomous safe emergency landing of a powered unmanned aerial vehicle (UAV) in the event of an engine failure. A landing approach trajectory is generated, including a downwind leg, initiating at an initiation point of the trajectory, an upwind leg, terminating at a selected touchdown point, and a U-turn leg, joining between the downwind leg and the upwind leg. The UAV is directed to the initiation point to follow the downwind leg. A glide ratio of the UAV is repeatedly determined based on current flight conditions. A current turning point is repeatedly determined along the downwind leg based on the determined glide ratio, the U-turn leg initiating at the current turning point. When the UAV arrives at the current turning point, the UAV is directed to follow the U-turn leg and the upwind leg, for landing the UAV at the selected touchdown point. | 06-04-2015 |
