Fall of shock wave from a supersonic aircraft into the geological media

摘要

The paper is devoted to the study of wave phenomena arising in a geological massif as a result of impact of shock wave generated from a flying supersonic aircraft. The types of scattering were investigated depending on the flight velocity of the supersonic aircraft. The critical values of flight velocities that affect the types of waves formed in the geological environment were identified. The results obtained in the two-dimensional case were extrapolated to the three-dimensional case. The effect on the topography of Earth’s surface was investigated. Seismograms were built, their features were identified and explained, and optimal types of seismic surveys were studied. The Wave Logica method was used to analyze wave phenomena. To calculate wave patterns, the numerical grid-characteristic method was used to solve the joint boundary-value problem of elastic and acoustic wave equations. A method for the numerical simulation of these wave phenomena by setting N-shaped plane wave in the air acoustic medium was proposed, justified and used. The results can be used to find the altitude and flight velocity of supersonic aircraft based on seismograms.
