Abstract
A method for manufacturing an aircraft door with an integral structure. The method includes the following steps: producing a forged blank (7); die-cutting the forging blank (7) between a substantially smooth lower die (8) and an upper die (9) defining a plurality of cells and producing a die-cut part having a honeycomb structure having an open face and a closed face closed by a wall; an inner wall of the honeycomb structure is machined to define at least one recess defined by a web connecting the closed face and the open face and a base protruding substantially perpendicular to the web on the open face of the die cut component.”
