Abstract: An air intake structure for an aircraft nacelle including an air intake lip with a U-shaped cross section which is open towards the rear, with a rear end, an acoustic panel including an inner wall, wherein the air intake lip has at a rear end a contact surface oriented towards the inside of the air intake lip, in that the contact surface takes the shape of a bevel which points towards the rear and against which the inner wall is placed, in that at the point of the bevel, the inner wall runs on from the air intake lip and in that level with the contact surface, the air intake lip is fixed to the inner wall by first fasteners. The bevelled shape restricts the possibility of dust and water being halted in their progress and blocking up the air intake structure as a result.

Abstract: A method is provided for destroying a blind fastener joining at least two parts. The blind fastener includes, but is not limited to a body situated in the holes provided in the joined parts, with a head at each end thereof, and portions of which protrude above the level of the holes. The method also includes, but is not limited to withdrawing the accessible head of the fastener, and creating a hole that passes through the fastener. An insertion device is configured to restrain the remainder of the fastener in the hole, which has an elongated body having a diameter smaller than or equal to that of the hole and an expandable head at one end thereof The insertion device for restraining the remainder of the fastener being immobilised or capable of only limited movement relative to the joined parts, and expelling the remainder of the fastener from the holes.

Abstract translation: 提供一种破坏连接至少两部分的盲紧固件的方法。 盲紧固件包括但不限于位于设置在接合部分中的孔中的主体，在其每个端部具有头部，并且其一部分突出于孔的高度之上。 该方法还包括但不限于撤回紧固件的可触及的头部，并且产生穿过紧固件的孔。 插入装置构造成将紧固件的其余部分限制在孔中，该孔具有直径小于或等于孔的直径的细长主体和在其一端的可扩张头。用于限制其余部分的插入装置 紧固件被固定或仅能够相对于连接的部件有限的移动，并且将其余的紧固件从孔中排出。
