Oscillations in engine thrust are due to nonstationary dynamic processes in the combustion chamber. The presence of vortexes in the combustion product flow in the combustion chamber can lead to liquid rocket engine (LRE) dynamic instability with a re

Sonic drilling is a soil penetration technique that strongly reduces friction on the drill string and drill bit due to liquefaction, inertia effects and a temporary reduction of porosity of the soil. Modern studies to assess the effect of the vibrati
