Aircraft propulsion assembly including a supporting structure between an engine assembly and a primary structure of a pylon

An aircraft propulsion assembly comprising:

• an engine assembly that extends from front to rear along a longitudinal axis and includes at a front a front part and at a rear of the front part a rear part corresponding to a part of an engine core, the front and rear parts each having a circumferential shape, the front part having a section larger than that of the rear part,
• a primary structure of a pylon,
• an engine-attachment system connecting the primary structure and the front part of the engine assembly, the engine-attachment system including at least one front attachment directly connecting the engine assembly and the primary structure;
• at least one supporting structure extending along an axis parallel to the longitudinal axis and at least a part of a circumference of the rear part of the engine assembly, said supporting structure being separate from the rear part of the engine assembly, distant from the engine core and connected to the front part of the engine assembly, and
• the engine-attachment system comprising at least one rear attachment offset rearwardly relative to the front attachment and connecting the primary structure and the least one supporting structure.
