PROBLEM TO BE SOLVED: To solve a problem with an unbalanced mass which may occur in a low pressure compressor without correcting an existing engine. SOLUTION: An unbalanced mass effect may occur in the low pressure compressor 5 of the aircraft engine. To increase the rigidity of an assembly and reduce cracking which may occur by an accidental unbalanced mass, a reinforcement material 20 is proposed. One end 22 of the reinforcement material may be fixed to an engine casing 7 through a structural arm 10, and the other 32 may be fixed to the compressor 5 desirably on the upstream side of a third guide vane RD3. The reinforcement material 20 is advantageously formed of two portions fixed to each other, and its manufacture is optimized so as to suppress the addition of a weight required for the presence thereof.
