Aircraft`s structure e.g. central section, rigidifying ventral spanwise beam, has sealing units provided for ensuring sealing between beam and sealed wall which comprises cut adapted to section of beam, where beam traverses sealed wall

摘要

#CMT# #/CMT# The beam (12) has a sealed partition (32) provided in a same plane as of a sealed wall (18) which comprises a cut adapted to a section of the beam, where the beam is formed of composite material. Sealing units (30) provided for ensuring the sealing between the beam and the sealed wall, where the beam traverses the sealed wall. A U-shaped lower flange has branches surmounted by two lateral longerons, and a longitudinal rib extends on a part of the length of the beam. #CMT#USE : #/CMT# Used for being arranged in a lower part of a fuselage of an aircraft for rigidifying a structure e.g. central section, of the aircraft. Can also be applied to lateral longerons bordering front and rear landing gears. #CMT#ADVANTAGE : #/CMT# The beam eliminates the need for metallic parts for transferring loads from one side to another side of the sealed wall such that the beam is compatible with the sealed wall provided inside the fuselage. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a vertical longitudinal sectional view of a beam traversing a sealed wall. 12 : Ventral spanwise beam 14 : Fuselage 16 : Non pressurized zones 18 : Sealed wall 30 : Sealing units 32 : Sealed partition.
