The method of aviation systems diagnostics according to the admissible level of non-failure operation probability

Abstract

The paper presents the methods of forecasting reliability of the created devices, design of devices with the given reliability and comparison of reliability of various aviation systems. Calculated relations at various types of redundancy in tests, prolongation of service life of blocks of aircraft, the basis of which is methodology of estimation of residual resource are resulted. The existing methods of reliability analysis are systematized and studied. The problems of uncertainty of information on input data at calculations by classical methods are stated. It is postulated that the principle of comparability of results of quantitative estimations of technical systems assumes the use of uniform composition of initial data for a certain reporting period of time, unity of generalized and private indicators used as well as unity of assumptions and limitations accepted. The application of general and elementary formulation of the state estimation of complex mechanisms with the use of diagnostic matrix and recognition theory to determine the state of technical objects is shown. Stages of the general process of object diagnostics are described, which consist in determination of parameter changes at influence on object elements and further processing of the obtained results using synthesis and analysis methods.
