Позорная война рф против Украины

Начата 20 февраля 2014 и полномасштабно продолжена 24 февраля 2022 года. С первых же минут рф ведет ее с нарушением законов и правил войны, захватывает атомные станции, уничтожает бомбардировками мирное население и объекты критической инфраструктуры. Правители и армия рф - военные преступники. Все, кто платит им налоги или оказывают какую-либо поддержку - пособники терроризма. Народ Украины вас никогда не простит и ничего не забудет.

Peculiarities of application of linear AR and ARMA processes as mathematical models of vibration signals from own needs engines of TPP and CHPP and engines of wind-power units were studied. Features of construction of the prototype of a wireless information-measuring system (IMS) for diagnosing the condition of such engines were determined. The paper gives the results of experimental studies of application of IMS prototype in the case of investigation of own needs engine vibrations, namely of DKRAI – 4519-4V engine at Darnitsa CHPP, using international standards. New mathematical models were derived of static and dynamic processes in aeromechanical regulation means of rotors of wind-power units (WU) with centrifugal regulator, their experimental verification was conducted and they were used as a basis for development of a procedure for selection of the parameters and characteristics of aeromechanical regulation means of rotors of wind-power units with centrifugal regulator, and of a procedure of determination of loads and strength analysis of wind-power unit blades, which will be used by developers when designing new wind-power units. 8 Ref., 3 Fig.
