Abstract

In an aircraft having a cylindrical or tapered pressurized fuselage, an internal bulkhead includes a central calotte shaped part of particular thickness and made of a fiber-mesh, a woven or a fleece-like reinforcement of a particular radius of curvature and preferably made of Kevlar: a possibly thicker edged portion of, preferably, carbon fiber-reinforced material, which possibly matches any taper of the fuselage, and a transition from the calotte shaped part to the edge having a radius of curvature smaller than the particular radius of the calotte shaped partition.
