PROBLEM TO BE SOLVED: To provide a separating system which is high in reliability, and in which static and dynamic stresses applied on a turbojet are taken into consideration. SOLUTION: A separating system is a system for separating a fan 10. A turbojet includes a movable fan shaft 4 provided at bearings 6, 8 connected to a stationary structure 28 of the turbojet by bearing supports 26, 30, respectively. The bearing supports are fixed to the stationary structure of the turbojet via mechanical links 32, 34 that work so as to transmit a force produced by the rotation of the fan during a normal operation of the turbojet. The mechanical links include explosives capable of dividing the links, and the explosives are controlled by a full automatic digital engine control (FADEC) computer 40 based on a means 44 for measuring mechanical stresses of the turbojet, and a computer model 46 for simulating static, dynamic and thermodynamic behaviors of the turbojet.
