Abstract

A geometric representation of nonlinear system dynamics in phase space is one of the most evident and significant techniques for investigation of system instability. A state of the nonlinear system is represented by point in the phase space at each moment of time. While the state changes the point generates a phase trajectory in the space. The phase trajectories describing transition of the system is named as its phase portrait. The phase portrait provides full and clear view of the nonlinear system dynamics. Basing on these considerations some geometric techniques are discussed to analyze self-oscillations in throttled liquid rocket engines.
