Aircraft comprising at least one engine attachment system which has coplanar anchoring points on the engine

An aircraft comprising:

• at least one propulsion unit comprising:
• an engine which has an engine axis, as well as a vertical median plane and a horizontal median plane that pass through the engine axis;
• at least one primary structure of a pylon;
• and
• at least one engine attachment system connecting the engine and the primary structure;
• wherein the engine comprises a fan casing and a jet engine hub;
• wherein the primary structure comprises;
• a central body;
• at least first and second right extensions and at least first and second left extensions, the at least first and second right extensions and the at least first and second left extensions being positioned on either side of the central body;
• and
• connected to the central body, at least one right reinforcement, which connects the at least first and second right extensions, and at least one left reinforcement, which connects the first and second left extensions;
• wherein the first right extension and the first left extension are offset towards a front, in a longitudinal direction parallel to the axis of the engine, relative to the second right extension and the second left extension;
• wherein the first right extension and the first left extension are positioned substantially in a first transverse plane;
• the engine attachment system comprising at least three connections, each connection of the at least three connections comprising:
• a first anchoring point rigidly secured to the primary structure;
• a second anchoring point rigidly secured to the engine;
• and
• an articulation connecting the first anchoring point and the second anchoring point of a same connection of the at least three connections;
• wherein at least two of the first anchoring points are rigidly secured to the first right extension and the first left extension;
• and
• wherein the second anchoring point of each of the at least three connections being located approximately in a second transverse plane.
