Unbalanced mass effects can occur at the low pressure compressor () of an aircraft engine. Stiffeners () are proposed to increase the stiffness of the assembly and therefore reduce possible cracks due to accidental unbalanced masses, one end () of the stiffener can be fixed to the engine casing () at the structural arm (), and the other end () can be fixed to the compressor (), preferably at the upstream face of the third guide vane (RD). Advantageously, the stiffeners () are made of two parts fixed to each other; their manufacturing is optimized to limit the additional weight due to their presence.
