  • Patent number: 11591960
    Abstract: The invention relates to an air intake of an aircraft turbojet engine nacelle, extending along an axis X, in which an air flow circulates from upstream to downstream, the air intake extending circumferentially around the axis X and comprising an inner wall, which faces the axis X in order to guide an inner air flow, and an outer wall, which is opposite the inner wall, for guiding an external air flow, the walls being connected by a leading edge and an inner partition so as to delimit an annular cavity. The air intake comprises means for injecting at least one hot air flow into the inner cavity and at least one ventilation orifice formed in the outer wall in order to allow the hot air flow to escape after heating the internal cavity, the air intake comprising at least one disruption member of the external air flow, positioned upstream of the ventilation orifice, which extends outwardly from the outer wall.

  • Publication number: 20230046876
    Abstract: A thrust reverser including a stationary structure, a lower door and an upper door. This reverser includes at least one deflector configured to be able to redirect forward from the stationary structure a portion of fluid exiting the reverser according to a trajectory oriented towards a lateral opening extending between the stationary structure and the upper door. Such a deflector makes it possible to improve the control of the air current lines acting on a tail unit and in particular on a control surface of an aircraft equipped with such a reverser when the latter is in thrust reversal configuration, thereby making it possible to improve the controllability of this aircraft.

  • Publication number: 20230032837
    Abstract: The invention relates to a method for determining the value of one or more parameters relating to the state of health of at least one accumulator of a battery that is intended to provide electrical energy to an external application. A first state-of-health parameter related to the resistance of at least one electrochemical element of the battery is determined according to the method comprising:—a step (1) of determining the value of the state of charge of the electrochemica 1 element, expressed as a percentage of a maximum state of charge; —a step (2) of verifying whether the determined value of the state of charge belongs to a sought range; —a step of repeating, as long as the result of the verification step (2) is not positive, the determination step (1) and then the verification step (2); —calculating the value of the first parameter as a function of at least the value of the state of charge determined during the last determination step (1).

  • Publication number: 20220316427
    Abstract: A thrust reverser for a turbojet aircraft nacelle includes a fixed structure, a movable structure and an actuator. The actuator extends along a main axis and is connected by a first connection to the fixed structure and by a second connection to the movable structure for the deployment of the movable structure between a direct jet position and a reverse jet position. The actuator is also connected to the fixed structure by a third connection arranged longitudinally between the first connection and the second connection. An axis of the third connection is radially eccentric from the main axis and the third connection allows a predetermined displacement of the actuator with respect to the fixed structure.

  • Publication number: 20220250757
    Abstract: An assembly including a nacelle element, such as a cover, a device for locking the nacelle element, a key for locking/unlocking the locking device and an indicator for indicating the position of the locking device. This assembly includes a control device which is configured to be actuated by the key when the key is withdrawn from the locking device so as to make the indicator move from a first state to a second state, the state of the indicator being representative of the locked or unlocked position of the locking device.

  • Publication number: 20220187385
    Abstract: The invention concerns a method for estimating the state of health (SOH) of an electrochemical element, comprising: initiating a charging or discharging operation of the electrochemical element; measuring values representing deformations of the electrochemical element while the charging or discharging operation is being performed, the deformation values measured forming a deformations image signal according to the quantity of electricity passing through the electrochemical element over time; comparing the deformations image signal and a reference image signal, one or more differences obtained by the comparison characterising an estimation of the ageing of the electrochemical element.
