Embodiment Construction

[0028] FIG. 1 is a side view of a fuselage section 100 according to an embodiment of the present invention.

[0029] The fuselage section 100 is an integral part of an aircraft (not further shown).

[0030] The fuselage section 100 includes an outer shell 102 formed with a doorway 104 . In each case, together with the two frames 106 represented here only by lines, a door frame structure 108 is formed with the outer shell 102 . Said frames 106 are arranged continuously along the longitudinal X-axis of the aircraft.

[0031] The construction of the respective door frame structures 108 will be described in further detail below with reference to FIG. 2 , which is a cross-sectional view along line I-I of FIG. 1 .

[0032] In addition to the frame 106 and the outer shell 102, the door frame structure 101 includes a fiberglass metal laminate 110, which is arranged on the outer shell 102 and the frame 106 (especially its outer flange 200). )between. The fiberglass metal laminate 1...

Abstract

The present invention provides a door frame construction (108) in particular for an aircraft or spacecraft, comprising: a former (106); a fibre metal laminate (110) which is connected to the former (106); and an outer skin (102) which is connected to the fibre metal laminate (110).

Description

technical field [0001] The present invention relates to a fuselage section and door frame structure for an aircraft or spacecraft. Background technique [0002] Aircraft fuselage sections are usually produced using a so-called lightweight construction skin whose interior is reinforced by a two-dimensional structure of stringers extending longitudinally across the fuselage and frames extending transversely across the fuselage. [0003] Furthermore, it is known that fuselage sections of this type are provided with doorways to allow access to the interior of the fuselage during operation of the aircraft. A fuselage section of this type is disclosed, for example, in DE 10 2007 015 007 A1. [0004] Known fuselage sections have a doorway located between two frames, which may also be referred to as door frame frames. The fact that the doorway weakens the fuselage section of this range means that there are high demands especially on the fatigue limit of the doorjamb frame. In kno...
