FITTING FOR TRIMMING THE HORIZONTAL STABILISER OF AN AIRCRAFT

Fitting (30) for trimming the horizontal stabilizer (1a) of an aircraft, made of composite material, said fitting (30) comprising side walls (2a and 2b) of a torsion box as well as joining elements (3a, 3b) which join the fitting (30) to the frames of the tail fuselage (1) of the aircraft, said side walls (2a, 2b) being joined together by means of a central element (4) which comprises a first end part (4a) joined to the first side wall (2a) of the fitting (30), a second end part (4b) joined to the second side wall (2b) of the fitting (30) and a central part (4c) which joins together said end parts (4a, 4b), the fitting (30) moreover comprising end elements (5a, 5b) which are joined to said side walls (2a, 2b) on their outer face, said fitting (30) having, owing to its greater rigidity in response to side load and vertical load stresses which tend to close the side walls (2a, 2b), its greater integration and the simplicity of the load path, an optimum structural behaviour in response to the aircraft stresses.
