Abstract: The disclosure herein proposes identifying precursors to all the phenomena which can have an impact on the service use of an aircraft. It relates to a system for predicting failures in an aircraft, including a processor configured to analyze a current behavior of at least one flight parameter of the aircraft to detect any deviation of the current behavior relative to a predetermined behavior model of the parameter, the behavior model being determined from a plurality of series of learning data relating to the parameter collected during the flights of a set of aircraft.

Abstract: A fuel injector has a plurality of injection fuel delivery passages, which transport fuel from a proximate end to an injector cavity near the distal end of the fuel injector, wherein less than a total number of injection fuel delivery passages include an orifice. This configuration provides a reduction in fueling variation from pulse to pulse (multi-pulse) with respect to pulse separation due to pressure variation while allowing a sufficient amount of fuel flow to the injector cavity. Thus, the consistency of Start-Of-Injection (SOI) and opening rate both improve significantly and advantageously. For compactness, the orifices may be positioned in a cover plate used to retain the components of the injection control valve assembly and may further be arranged in an arc segment when viewed along a longitudinal axis.

Abstract: A system and method is provided for controlling the amount of fuel delivered during an injection event by measuring the drain fuel flow from a valve that controls the injection event.

Abstract: The invention concerns a recording and/or storage device comprising at least a camera (V1 to V4) mounted on the vehicle (20) and designed to deliver continuously a series of images and an electronic circuit (21) capable of transferring at every moment, into a buffer (23), the images delivered by the camera (V1 to V4) so that at every moment, said storage contains a sequence of images photographed by the camera for a predetermined time interval preceding said moment, and an impact sensor (25). The transfer of the data contained in the buffer (23), into a storage memory (24) for subsequent playback can be performed in response to a command carried out by the driver or optionally automatically following detection of an impact.
