Manufacturing window frame for installation in exterior shell of aircraft involves providing semifinished part composed of multiple, individual substructures

摘要

A window frame (1) is manufactured by providing a semifinished part composed of multiple, individual substructures. Method of manufacturing a window frame for installation in an exterior shell of an aircraft with an aircraft structure, where the window frame comprises outer and inner flanges (2, 3), and vertical flange (4) arranged perpendicular to the inner and outer flanges and between the inner and outer flanges, where the outer flange is adapted for a connection to the aircraft structure for connecting the window frame to the aircraft, and where a window element abuts against the inner flange for support involves providing a semifinished part composed of multiple, individual substructures; inserting the semifinished part into a molding tool; performing an injection of resin into the molding tool, wherein the injection is made under pressure and temperature; and hardening the semifinished part after the injection in the molding tool for forming the window frame.
