Mounting system inserted between an aircraft engine and a rigid structure of an attachment strut fixed under a wing of this aircraft, the system including a forward mount, an aft mount, and a device for resisting thrusts generated by the engine, wherein:

• said device comprises two lateral actuators arranged one on each side of the engine, each actuator being provided with a rod in which an aft end is connected to one of said forward and aft mounts and for which one forward end is a piston located inside a chamber fixed to a forward part of a central casing of the engine, said chamber comprising a forward compartment and an aft compartment separated by said piston;
• and wherein said thrust resistance device also comprises a hydraulic piston device comprising a piston fixed to the forward mount and located inside a chamber fixed to said forward part of the central casing of the engine, said chamber comprising a forward compartment and an aft compartment separated by said piston, said forward compartment of said chamber of the hydraulic piston device being hydraulically connected to said aft compartments of the lateral actuators.
