METROLOGICAL SUPPORT OF ON-BOARD VIBRATION CONTROL SYSTEMS
- A.I. Serebryansky, A.Yu. Shuvaev, M.Yu. Ermakov
The high load-speed modes of operation of modern aircraft are indicated. Therefore, there arises the need to register
and control the free and forced oscillations of the tail of the airframe. A brief analysis of vibration modes is given. The most
destructive types such as buffing and flutter were identified. All types of complex vibrations are presented as a set of simple
harmonic vibrations. A scheme of on-board vibration control consisting of a vibration transducer, an electronic unit, an alarm and a
vibration value indicator is proposed. The efficiency of using such schemes of on-board vibration measuring systems, their technical
and hardware components are determined.
