Precise measuring-computational predictive monitoring-the conditional of self-organization of the life cycle

摘要

Formation of aviation which was laid down by the fundamental works of N.E.Zhkovsky and its further development at the forefront of scientific and technological progress occurs in the constant overcoming of the information deficit.The biosphere gives samples of successful provision of reliable functioning,but the perfection of living organisms is achieved through natural selection,which lasts for thousands of years.Improving the objects of the technosphere requires an increase in the level of information and metrological support for the production and operation of facilities.At present,the parameters of the basic structural materials are known with relative error at the level of percent or its fractions.The metrological level of the control and diagnostic equipment is the same.The lack of information is compensated by long and costly experimental and production work-up,as well as by the system of preventive maintenance and inspections,but is not a complete guarantee against accidents and catastrophes.The existing information barrier can be overcome by the transition from amplitude to phase measurement methods.The phase-chronometric version of this approach provides effective monitoring of the cyclic systems-from the clock mechanism to the powerful turbo-aggregate with a relative error of at least 5-10-4 % at the industrial frequency.The combination of a precise phase-chronometric system with a mathematical model of the object that is constantly refined from the received measurement data makes it possible to realize a measurement and computational monitoring of its technical state and emergency protection.Simultaneously,the problem of information and metrological support of the life cycle of objects included into the self-organizing system of the Research Institute-Design ofiice-Plant-operated facility is being solved.
