Abstract: A method and device for monitoring an avionics software application via its execution duration, related computer program and avionics system are disclosed. In one aspect, the method, executed on a platform hosting an operating system, is implemented by an electronic monitoring device. The avionics software application includes one or several software processing operations to be executed, the platform is configured to be on board an aircraft. The method includes: monitoring the execution duration of the avionics software application, through the verification, upon expiration of at least one predefined execution times, of the completion of the execution of at least one software processing operation of the avionics software application; and updating a status of the avionics software application based on the monitoring of the execution duration of the avionics software application.

Abstract: The centrifugal pump with an open-faced impeller comprises at least one open-faced impeller having blades placed inside a casing defining both a delivery pipe and a suction pipe facing the base of the blades situated in the vicinity of a central shaft for driving the impeller. An active axial balancing system for the rotary assembly is integrated in the impeller and comprises a balancing chamber interposed between the rear face of the body of the impeller and an outer rear portion of the casing, the impeller itself acting as the balancing turntable. A shroud-forming intermediate part is prevented from rotating relative to the casing and is interposed between an outer front portion of the casing and the impeller, a cavity is formed between the outer front portion of the casing and the intermediate part to receive a back pressure of predetermined value serving, in operation, to maintain small clearance without contact between the intermediate part that is prevented from rotating and the blades of the impeller.

Abstract: A centrifugal pump with an open-faced impeller for conveying a working liquid, the pump comprising at least one open-faced impeller provided with blades placed inside a casing defining a suction pipe facing the bottoms of the blades in the vicinity of a central shaft that drives the impeller and forming a part of a rotary assembly, and a delivery pipe fitted with a fixed diffuser disposed facing the peripheral ends of the blades. An active axial balancing system for the rotary assembly, which balancing system is integrated in the impeller and comprises a balancing chamber interposed between the rear face of the body of the impeller and an outer rear portion of the casing.
