Abstract
Pressure bulkhead apparatus is disclosed. An example bulkhead apparatus includes a frame and a plurality of beams radially spaced relative to a longitudinal axis of the frame. A beam from the plurality of beams has a first end and a second end. A beam end assembly couples the second end of the beam and a stringer of a fuselage. The beam end assembly enables the second end of the beam to move relative to at least one of the frame or the stringer.
Claims21
A bulkhead apparatus comprising:
- a frame;
- a plurality of beams radially spaced relative to a longitudinal axis of the frame, a beam from the plurality of beams having a first end and a second end;
- and
- a beam end assembly to couple the second end of the beam and a stringer of a fuselage, the beam end assembly to enable the second end of the beam to move relative to at least one of the frame or the stringer.
1 more element
An aircraft comprising:
- a fuselage having stringers aligned along a length of the fuselage;
- a bulkhead coupled to the fuselage, the bulkhead having a web and beams, the beams radially spaced relative to a longitudinal axis of the web, each beam including a first end and an opposing second end, the first end being radially inward adjacent a center of the web, the second end being radially outward adjacent a circumference of the web;
- and
- a respective beam end assembly to pivotally couple the second end of each beam and a respective one of the stringers, the beam end assemblies are configured to eliminate moment loading at an interface between the beams and the stringers.
1 more element
A bulkhead comprising:
- a hub;
- a beam having a first end and a second end opposite the first end, the first end coupled to the hub, the second end being radially outward relative to a frame;
- a first fitting coupled to the second end of the beam;
- a second fitting having a first portion and a second portion, the first portion coupled to the frame and the second portion to couple to a stringer of a fuselage;
- and
- a linkage assembly pivotally coupled to at least one of the first fitting or second fitting.
