Abstract

Parameters of stress-strain state of the output (nozzle) unit of the progressive solid-propellant rocket engine (SPRE) are determined for impact loads during nozzle separation by means of discrete mass approach. Dynamics of elastic wave processes is investigated for direct and inverse impact vibrodynamic loading of the nozzle. Numerical experiment allowed obtaining assessment of distribution of minimal strength safety factors of the SPRE output unit structure.
