Abstract: A fixed-wing aircraft (1) at least comprises at least one vortex generator (6, 7, 8, 11) movable through an outer surface of the aircraft (1) between a retracted state and a fully extended state by at least one electric motor (12), this at least one electric motor (12) being exclusively adapted to actuate this at least one vortex generator (6, 7, 8, 11), and comprises an electronic control unit (13) adapted to control operation of the at least one electric motor (12) for actuation of the at least one vortex generator (6, 7, 8, 11).

Abstract: The system according to the invention comprises: an electrical network, and a regulating assembly. The regulating assembly includes a secondary electric power source, a conversion assembly for an additional electric power injected on the electrical network, the conversion assembly being able, in a first configuration, to consume the additional electric power present on the network to create a supply fluid of the secondary source. The assembly includes a reservoir for each supply fluid, to collect the supply fluid produced by the conversion assembly.

Abstract: This assembly (24) includes an emergency electricity generator (60). The electricity generator assembly (24) is controllable between an inactive rest configuration and an active configuration for producing energy in which the emergency electricity generator (60) delivers emergency electric energy to the electric network (20), without being electrically powered by the electric network (20). The emergency electric power generation assembly (24) is able to be placed in an intermediate standby configuration, in which the emergency electric power generation assembly (24) is electrically powered by the electric network (20) so that the emergency electricity generator (60) produces standby electric energy of lower power than the power delivered by the emergency electricity generator (60) in the active configuration.

Abstract: The system according to the invention comprises: an electrical network (20), and a regulating assembly (24). The regulating assembly (24) includes a secondary electric power source (58), a conversion assembly (60) for an additional electric power injected on the electrical network (20), the conversion assembly (60) being able, in a first configuration, to consume the additional electric power present on the network (20) to create a supply fluid of the secondary source (58). The assembly (60) includes a reservoir (62A, 62B) for each supply fluid, to collect the supply fluid produced by the conversion assembly (60).

Abstract: The invention relates to a heat exchanger.
