Section of aircraft fuselage and aircraft including one such section

Abstract

The invention relates to a section of fuselage for an aircraft, comprising frames and bays for receiving cabin windows (11). According to the invention, at least some of the frames include at least one frame segment that surrounds at least one bay, said frame segment comprising two branches (15, 16) that are disposed to the side of the bay. The ends of the branches are attached to each of the ends (17, 18) of the frame segment such as to form a Y.

Description

technical field [0001] The invention relates to an aircraft fuselage segment and an aircraft comprising such a segment. Background technique [0002] Commercial aircraft are known to include a generally quasi-cylindrical fuselage reinforced by stiffening elements such as spars and frames, to resist mechanical constraints imposed, for example, in flight. [0003] In commercial aircraft, for example, openings are provided in the side walls of the fuselage to accommodate windows and enable passengers to directly view the environment outside the fuselage. [0004] However, these windows create a number of disadvantages. First of all, windows on an airplane must provide some comfort for passengers by providing thermal and acoustic insulation of the interior space of the fuselage from the outside world. It must also be airtight and watertight. [0005] The window frames, usually riveted to the outer skin of the fuselage, must also resist mechanical constraints such as loads due...

AI Technical Summary

Problems solved by technology

[0013] However, this assembly represents a difficult and time-consuming task for the operator

Therefore, this assembly is expensive in terms of the delay of the aircraft in maintenance situations

[0014] Moreover, these specialized reinforcements of the side walls of the fuselage also mean additional weight that has a negative impact on the fuel consumption of the aircraft
