La présente invention concerne une entrée d'air (10) d'un turbomoteur (2) d'aéronef (1) comportant un conduit d'acheminement (20) d'air délimité par une paroi latérale (21) et prolongé par un conduit d'entrée dynamique (30), ledit conduit d'entrée dynamique (30) s'étendant selon un axe dynamique (AX1) vers une section de passage frontale (31), ledit conduit d'entrée dynamique (30) étant pourvu d'une grille (40) de protection contre l'ingestion de corps extérieurs. La grille (40) étant apte à effectuer une translation selon ledit axe dynamique (AX1) par rapport à ladite section de passage frontale (31), ladite entrée d'air (10) comporte au moins une entrée latérale (50) ménagée dans ladite paroi latérale (21) et un moyen d'obturation (41) de ladite entrée latérale (50) mobile par rapport à cette entrée latérale (50), ladite entrée d'air (10) comportant un moyen de déplacement (60) commandé par ladite translation de la grille (40) pour requérir un déplacement dudit moyen d'obturation (41) par rapport à ladite entrée latérale (50).
摘要:
The invention relates to a device for opening a passenger door (1) of an aircraft in case of emergency, which is fastened so it is manually pivotable on the fuselage (3) of the aircraft via a hinge and/or support arm configuration (2), an auxiliary-energy-operated emergency opening drive (4) being provided between the fuselage (3) and the passenger door (1), which automatically opens the passenger door (1) in accordance with an emergency control unit (5), the auxiliary energy for the emergency opening drive (4) being pyrotechnic energy, whose gas expanding inside an expansion chamber (6) after triggering by the emergency control unit (5) impinges the emergency opening drive (4) with pressure medium to open the passenger door (1). The emergency opening drive (4") comprises a turbine (13) for generating a rotational movement from the pyrotechnic energy, which works together with a downstream reduction gear (14) to open the passenger door (1).
