ABSTRACT:
The invention discloses a fuselage which is subdivided into a fuselage lower part (1) and a shell-shaped upper fuselage portion (3) where the upper fuselage portion (3) is provided with windows arranged in rows (12, 13), the windows being formed by inserted pieces (8) with the fuselage moulded around them, the windows being formed on an integral insert part (7). It is desirable that, on the one hand, the upper fuselage portion including the injection-moulded window pieces be of simpler construction and, on the other hand, should have a continuous external fuselage surface extending continuously without any conspicuous joint line down to the joint with the fuselage lower part. This is accomplished in that the upper fuselage portion (7) is of single-piece construction down to the joint (2) to the fuselage lower part (1) with the windows being surrounded by said upper fuselage portion, and in that the elongated insert part (7) of shell-shaped construction continuously lines the upper fuselage portion piece (3) on the inside. The simplified single piece construction of the upper fuselage portion provided with windows is achieved by the use of the insert part which is conveniently made by injection moulding.
