Device for coupling a propulsion system to an engine pylon of an aircract, and corresponding aircraft

A device for coupling a propulsion system to an engine pylon of an aircraft, said device comprising:

• a baseplate in a shape of an inverted T, said baseplate comprising a base configured to be fastened to said propulsion system and a first wall extending substantially perpendicularly to said base, said first wall comprising a first bore and a second bore extending, respectively, along a first longitudinal axis and a second longitudinal axis that are parallel to each other;
• a first sleeve and a second sleeve that are tubular, each comprising a first portion fitted respectively through said first bore and said second bore, said first and second sleeves each comprising a second portion a first end of which extends in a continuation of said first portion towards said engine pylon and a second end of which is configured to interact said engine pylon, said first sleeve comprising a first central bore coaxial with said first longitudinal axis and said second sleeve comprising a second central bore coaxial with said second longitudinal axis;
• fastening means comprising a first nut and a second nut configured to be rigidly connected to said engine pylon, a first fastening screw comprising a first fastening head from which extends a first threaded shank, said first threaded shank being fitted through said first central bore and being screwed to said first nut, and a second fastening screw comprising a second fastening head from which extends a second threaded shank, said second threaded shank being fitted through said second central bore and being screwed to said second nut;
• a second front flange and a second rear flange, said second front and rear flanges being arranged respectively on either side of said first wall, said second front flange comprising an eleventh bore and a twelfth bore extending respectively coaxially with said first and second longitudinal axes, said second rear flange comprising a thirteenth bore and a fourteenth bore extending respectively coaxially with said first and second longitudinal axes;
• a first spacer and a second spacer suitable configured to be arranged between said second rear flange and said engine pylon, said first spacer comprising a third central bore coaxial with said first longitudinal axis so that said first spacer is fitted onto said second portion of said first sleeve, and said second spacer comprising a fourth central bore coaxial with said second longitudinal axis so that said second spacer is fitted onto said second portion of said second sleeve;
• wherein said first portion of said first sleeve is fitted through said eleventh and thirteenth bores of said second flanges;
• wherein said first portion of said second sleeve is fitted through said twelfth and fourteenth bores of said second flanges;
• wherein each fastening head bears against said second front flange.
