Device for attaching an aircraft engine, comprising blocks for clamping an engine attachment with a wedge effect

A device for mounting an aircraft engine, comprising:

• a rigid structure including a first connecting plate;
• an engine attachment which attaches the engine on said rigid structure, said engine attachment including a second connecting plate which abuts said first connecting plate of said rigid structure along a contact surface between said connecting plates;
• and
• four wedge-effect tightening blocks each including first and second tightening jaws extending towards the connecting plates and presenting tilted bearing surfaces,
• wherein said first and second connecting plates globally have a shape of a quadrilateral such that said first and second connecting plates together define four corners,
• wherein each of the first and second connecting plates presents a bearing surface connected to an edge of the respective connecting plate, and the bearing surfaces of the connecting plates are opposite the contact surface of the connecting plates,
• wherein said tightening blocks respectively have a conjugate shape of said four corners and said tightening blocks are respectively applied at said four corners against said bearing surfaces of said connecting plates along a direction parallel to a plane of said contact surface between said connecting plates such that said tilted bearing surfaces of said tightening jaws contact said bearing surfaces of said connecting plates, such that said tightening blocks exert by a wedge-effect forces for tightening said connecting plates against each other along a direction perpendicular to said plane.
