FIELD: aviation.
SUBSTANCE: for determining the stresses, flight performance is measured by standard means during the entire flight time, from which the significant parameters are selected and systematized, their approximating functions are determined to obtain the final function of the stress dependence in the rotor shaft on the selected performance parameters, loads on the rotor shaft is calculated using a mathematical model, a message is generated if they are exceeded.
EFFECT: determination of the residual life and control of the admissible load level.
