  • Piloting assistance system and method for an aircraft
    Patent number: 11735056
    Abstract: A piloting assistance system for an aircraft comprises a flight management computer and a guidance computer. The flight management computer transmits speed setpoints to the guidance computer so as to pilot the aircraft in accordance with an initial speed profile or in accordance with an RTA speed profile following the reception of an RTA constraint. In response to the reception of a setpoint speed selected by a flight crew member in the presence of the RTA constraint, the guidance computer pilots the aircraft at the selected speed and the flight management computer determines a deselection point for returning to a predetermined speed profile while still complying with the RTA constraint. The guidance computer commands the display, on a navigation screen, of a symbol corresponding to the position of the deselection point.

  • Aircraft turbojet engine comprising two thrust reverser modules
    Patent number: 11692511
    Abstract: A turbojet engine with two thrust reverser modules. Each module includes an outer casing, an inner casing and a securing system for securing the inner casing to the outer casing which comprises first and second hoods. A housing between the hoods has a securing wall, a seal with a sausage secured to the securing wall, and a crusher rigidly secured to the second hood and arranged so as to crush the sausage towards the securing wall when the second hood goes from the spaced-apart position to the close-together position. Therefore, the sausage moves in the longitudinal direction, thus limiting shearing of the seal and transverse movements owing to the manufacturing and assembly tolerances and the movements in flight.
