Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Estimation of the Influence of an Intermittent Failure in the Control Loop on the Resource State of the Aircraft Hydraulic System S.A. SHILIN Тo аssess the impact of a moving failure on the resource state of vital aircraft componenets, it is proposed to use the dependence of the resource consumption of the most critical structural elements on the work of loading forces during bench tests of the power system according to the time between failures scheme, as well as load diagramm generated on board the aircraft during its operation. The problem of determining the resource consumption of a particular node in the conditions of a spontaneous malfunction of the control loop for anarbitrary period of the operating cycle is solved. Keywords: intermittent failure, resourse state, vital unit, loading diagramm, most critical structural element. DOI: 10.25791/pribor.7.2023.1421 Pp. 01-05.
