摘要:
The invention relates to a system for transmitting stresses at the intersection between a reinforcing frame and a stiffener in a fuselage and to a method for producing one such system. An aircraft fuselage includes stiffeners (4) interrupted by reinforcing frames (5). At said interruptions, the stresses experienced by the stiffeners (4) must be transmitted despite the presence of the reinforcing frames (5). Known solutions are difficult to manufacture and install and do not provide a simple stress transmission path when produced solely from composite materials. In order to solve this problem, the invention includes the creation of battens (15) that cover the ends (16) of consecutive sections (6) of a stiffener (4) and the skin (7) of the fuselage (1), extending under the reinforcing frame (5) in order to join said two consecutive sections (6).
