Work objective is to study the dynamics and stability of the complex hydromechanical systems and their elements with allowance for hydrodynamical cavitation effects. Research methods are mathematical modelling and experiments. The new following theoretical results are obtained: methods for calculation of parameters of three-dimensional turbulent gas flows and two-dimensional unsteady viscous flows in blade machines are developed; parameters of LPRE pumps cavitation flows are defined; the linear and non-linear theories of launch vehicle structural longitudinal oscillation for POGO-problem are developed; the Liquid-Propellant Rocket Engines Database is created; for the first time investigations are made to use hydrodynamical cavitation effects for intensifying drilling hard rock and other processes. Mathematical models, procedures and software, practical recommendations can be used for the NSAU enterprises, aircraft industry a nd the Ukraine's Ministry of ecological safety and natural resource.
