Title: Composite propeller blade for an aircraft
Inventor: LAURENCEAU ADRIEN
IPC: B29D99/00
Filed: 2014-06-25
Granted: 2021-07-27
Abstract: The invention relates to an aircraft propeller blade including a structure having an airfoil, consisting of at least one fibrous reinforcement (200) obtained by three-dimensional weaving of threads and made denser by a matrix and a spar (60) including a bulged portion (62) extending outside of the fibrous reinforcement and forming the shank of the blade, and a shaped portion (61) in a recess (206) provided within the fibrous reinforcement (200). The fibrous reinforcement (200) comprises a disconnection area (204) forming the recess (206) inside the fibrous reinforcement (200). The disconnection area (204) leads to the lower portion (220) and the rear edge (230) of the fibrous reinforcement (200) such as to form an opening (231) for inserting the shaped portion (61) of the spar (60) into the recess (206) of the fibrous reinforcement. The opening (231) on the rear edge (230) of the fibrous reinforcement (200) extends over a height (H231) that is shorter than the height (H204) of the recess such as to provide, on said rear edge (230), a retaining portion (232) that is at least partially in contact with the shaped portion (61) of the spar (60).

Abstract: A hydrostatic variator having a common yoke design and two or more bent axis piston drive units is disclosed in which the rotating group of a drive unit is arranged to be movable relative to the yoke to alter the angle between its drive shaft axis and rotating group axis independent of the other drive unit. This can be accomplished using movable sector plates coupled to the rotating groups that are arcuately movable within the yoke about the axis perpendicular to the respective drive shaft axes of the drive units. Such variators enjoy the response and packaging advantages of a common yoke design while still allowing dynamic adjustment of system size. In turn, varying system size allows for efficiency to be improved at conditions other than at the maximum design torque.

Abstract: Logging apparatus, methods and systems are presented for logging data from electronic detonators one at a time, in which a logger is placed into an automatic logging mode and begins transmitting read request messages in repetitive fashion until a response is received from a single connected electronic detonator, whereupon the logger obtains serial ID number and potentially other data such as a delay from the electronic detonator, after which the logger automatically proceeds without further user button presses to again initiate read request messages, by which a user can sequentially connect and disconnect a number of electronic detonators one at a time for quick expeditious logging. Also presented are automatic electronic detonator programming apparatus and processes in which a logger is placed into an automatic programming mode and the user connects electronic detonators one at a time for automatic or semi-automatic programming of delay times from internal memory.

Abstract: La présente invention concerne une libération électromagnétique réglable. Une culasse magnétique (102) est fixée sur un support (109); un conducteur (104) traverse le support et la culasse et est monté sur le support; un arbre (107) est monté sur la partie supérieure du support et est positionné au-dessus du conducteur; une tige de poussée (103) est montée sur l'arbre et tourne conjointement avec l'arbre en réponse au support; une armature (101) est fixée sur la tige de poussée; l'armature et la culasse sont espacées l'une de l'autre; deux mécanismes de réglage sont montés sur l'arbre et sur les deux côtés de la tige de poussée entre la tige de poussée et le support; un ressort de torsion (120) entoure l'arbre et est positionné dans le mécanisme de réglage; le mécanisme de réglage est en contact avec la tige de poussée; une tige de réglage (110) est pourvue d'une pluralité de surfaces (115) de réglage qui sont en contact avec le mécanisme de réglage et qui peuvent se déplacer dans la direction longitudinale. La force de ressort du ressort de torsion permet à la tige de poussée de tourner en direction de l'armature et de la culasse espacées. Lorsqu'un courant de forte intensité traverse le conducteur, l'armature et la culasse s'attirent l'une l'autre sous l'action de la force électromagnétique; lorsque la force électromagnétique est supérieure à la force de ressort, la tige de poussée tourne en direction de l'armature et de la culasse attirées; la tige de poussée heurte le mécanisme de libération de sorte à couper le circuit; la force électromagnétique disparaît; et la tige de poussée revient dans sa position initiale sous l'action de la force de ressort du ressort de torsion.

Abstract: A device for measuring voltage across a remote load comprises a power supply configured to output a first output voltage to the remote load. A switch is selectively movable from a closed position to an open position. A measuring circuit measures a load voltage across the load when the switch is in the open position and determines a voltage difference between the first output voltage and the load voltage. The measuring circuit may adjust the first output voltage to a second output voltage to compensate for the voltage difference. A second A/D converter may be coupled to the power supply the load capacitor. The second A/D converter may measure a voltage across a resistor wherein a change in the voltage indicates a change in the load voltage. The power supply may be adjusted to output a second output voltage to compensate for any change in load voltage.

Abstract: Hydraulic pulses are produced each time that a pulse valve interrupts the flow of a pressurized fluid through a conduit. The pulse valve includes an elongate housing having an inlet configured to couple to the conduit to receive the pressurized fluid, and an outlet configured to couple to one or more tools. In the housing, a valve assembly includes a poppet reciprocating between open and closed positions, and a poppet seat, in which the poppet closes to partially block the flow of pressurized fluid through the valve. A bypass passage is configured to connect with a valve actuation vent port such that when the poppet closes the valve actuation pressure is less than the difference between the pressure up stream of the pulse valve and a pilot within the poppet moves between disparate positions to modify fluid paths within the valve. When the valve is open, a relatively lower pressure is produced by a Venturi effect as the fluid flows through a throat in the poppet seat, to provide a differential pressure used to move the pilot and poppet.
