CONNECTION ELEMENT Russian patent published in 2012 - IPC B64C1/26 

FIELD: transport.

SUBSTANCE: invention relates to connection element, particularly, to aircraft wing central and lateral torsion boxes. Connection element 1 to connect first structural component with second structural component comprises section and reinforcing element 12. Said section is made from composite material and comprises base 2, face wall 3 and lateral wall 4. Face wall 3 makes first angle with base 2. Lateral wall 4 makes second angle with face wall 3 and this angle with base 2. Reinforcing element 12 is shaped so that to allow its fitting in composite section and connection with face wall 3. Reinforcing element is conjugated with first and second angles. Composite section angles are rounded and conjugated with reinforcing element rounded edge. Rounding radius of composite section angle inner layer equals that of reinforcing element edge 45'. Another version of connection edge includes introducing filler in clearance between composite section and reinforcing element 12. In the process of connecting structural components the fase 2 of each connection element 1 is connected with the first structural component (aircraft wing central torsion box) and the face wall 3 is connected with the second structural component (aircraft wing lateral torsion box).

EFFECT: solidity of connection element from composite material without increasing of it is thinkness.
