Abstract

Instability of dynamic systems with essentially nonlinear characteristics is very complicated problem to solve it. This problem is solved in the design process of various aerospace vehicles and power systems. A choking liquid jet engine is an example of the systems. The analysis of such systems is carried out by means of harmonic balance technique or using qualitative theory of differential equations. Yet another approach is phase portrait formation for the system. Bifurcations must be analyzed in addition to the phase portrait for the system with complicated nonlinearities.
