The fatigue characteristics of wing structural elements of a heavy transport aircraft are evaluated using a mathematical model of the aircraft aeroelasticity, taking into account the fuel fluidity in the wing fuel tanks. The basic possibility is demonstrated of using the dynamic and dissipative properties of nonstationary fuel to reduce the level of fatigue damage of wing structural elements during operation. The results of calculations for the An-124 aircraft are presented.
