Abstract

Une nacelle montée au-dessus d'une aile d'un avion. Une structure de support sur la nacelle au-dessus du pylône résiste aux forces dans différentes directions et comprend des supports de porte permettant à la porte d'être ouverte vers le haut. Une structure de retenue sur le pylône au-dessous de la nacelle résiste aux forces dans différentes positions, et comprend un rail de support fixe et plusieurs gâches. Chaque gâche comprend une première extrémité qui coulisse à l'intérieur du canal, et une seconde extrémité qui met en prise un verrou sur la porte fermée. Un pylône au-dessous de la nacelle supporte la nacelle et un moteur dans la nacelle au-dessus de l'aile, augmente l'efficacité aérodynamique, et peut comprendre un longeron latéral pour supporter le moteur depuis le côté. Un ensemble de joint ignifuge comprend une surface presse-joint et un joint ignifuge, et ce dernier n'est pas en contact avec le premier jusqu'à ce que la porte soit presque fermée, de sorte que la compression est sensiblement directe et que le frottement est réduit.
