Abstract: 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.
Index terms: airplane glider, vibration, vibrations, vibration control, buffing.
