SPECIAL CHARACTERISTICS OF AN ELASTIC INTERACTION BETWEEN ACOUSTIC SHOCK AND AIRCRAFT BOARD EQUIPMENT AT OVERCOMING THE SOUND BARRIER
National Technical University of Ukraine "Kyiv Polytechnic Institute"
The distribution mode of highly intensive acoustic radiation at overcoming sound barriers by aircrafts has been analyzed. The phenomenon is considered as an external disturbing factor that affects the construction of the aircraft, when its surface transforms from a completely solid state into the state of impedance (there is an elastic interaction). There has been established the cause of such internal phenomenon ("slam"), which occurs during the sound barrier; its structure in space and time and the impact of acoustical wave on aeronautical equipment to further advance in finding solution to the problem of reducing errors of inertial navigation equipment.
