Abstract. This paper considers an integrated tolerance control system with failure monitoring and prediction subsystems for aircraft safety management system (ASMS), which is relevant nowadays. The paper deals with the operational component of hydraulic system (HS) tolerance zones. The internal measured parameter is pressure, so it was necessary to find an algorithm that reflects its dependence on operating conditions, its coefficient of kinematic viscosity of the fluid, its temperature, operating time, ambient temperature and flight stage. The operational component of the tolerance zone can be derived from the obtained expression for the pressure by substituting the boundary values of the parameters included in this dependence.
While polling the sensors of the automatic control system it is necessary each time to calculate the range of variation of the parameter for the given stage of flight and other conditions with the help of algorithms for calculating the tolerance zone obtained in the paper. Moreover, the control system has to process a large amount of information using artificial intelligence (AI) methods which allows the safety of aircraft flight (SAF) to be managed.
Keywords: aircraft health management system, aircraft flight safety management system, automatic control system of aircraft hydraulic systems, operational pressure-tolerant zone.
