Abstract

The article is devoted to an important topic - the assessment of survivability of complex technical systems, discusses the need to develop a methodology of forecasting reliability of complex systems on the example of liquid rocket thrusters with running a part of composite materials under actual operating conditions for their successful practical use in the propulsion systems. It is proposed to use graph-analytical method of risk analysis "tree structures" (a method of prof. Romanovsky) to predict the behavior of such systems.
