Abstract

The object of research is the process of elastic interaction of an ultrasonic beam with a cylindrical module enclosing the airplane in the form of two circular shells of the same length coaxially connected by their ends, the hermetical gap between them filled with liquid.

One of the problematic areas of the study is that the dislocation of deck aviation in the open waist plane allows the means of detecting the suborbital and atmospheric reconnaissance of the enemy to determine undefined not only the initial coordinates but also its coordinate functions for the entire period of subsequent trajectory travel. Finally, the on-board glider equipment, taking this information as the original one, makes it possible, with anticipation, accurately, to fire at the theoretical trajectory of motion, thereby increasing the probability of hitting the target. Therefore, it is necessary to ensure 100 % masking of deck aviation at open launch positions. This will significantly reduce or completely eliminate and improve the efficiency and life-span of the aircraft as a whole.

It is shown that, when the case is subjected to symmetrical oscillations, which greatly exceed the resistance to antisymmetric vibrations, the sound permeability of the case elements will increase solely by bending vibrations. It is revealed that the «acoustic transparency» of the device case serves as an intensive transfer of the sound energy of the bending waves of the case and completely depends on the frequency of the acoustic radiation, as well as the incidence angles. Thus, by creating a circular or ellipsoidal enclosing cylindrical module in the form of two circular shells filled with liquid, it will be possible to quickly disassemble and place it over another object in a matter of hours.
