The actuality of solving the problem of fundamental researches of a new precision inertial navigation system (NS) in extreme conditions, which is the important constituent of the aviation gravimetrical system, is grounded. The classification of NS is resulted. The system of NS controlling has been improved.
The two-level vibration control system of complex rotation systems (aviation engines) is developed at the steady-state and non-steady-state modes of operation. At the first level the vibration control system supports the current control of actual levels of vibration at the harmonics of the rotor rotation. The second level is assigned for analysis of “normal vibration” in order to predict or detect small damages of engine rotary details on the bases of integrated usage of signal processing methods for damages diagnosis. The vibration control method is based.
