Tendency of Conductivity of Acoustic Vibration of the Design of Aircraft to Lowering with the Growth of Their Acoustic Loading

The study presents the results of an analysis of experimental data that make it possible to reveal the behavior of the parameters of fluctuation in design during a change in acoustic pressure amplitude with the concept of conductivity of acoustic vibration. The nonlinear behavior of the vibration response of the design of different compartments of the rocket and segments of panels when loading by their field of acoustic pressure is confirmed. The general patterns of nonlinearity are found; in particular, it is shown that conductivity tends to lower with growth in acoustic loading that is generally close to a power function.
