Mathematical modeling of stress-strain state of sliding nozzle in the process of shock — pulse loading

Defined shock pulse load construction sites promising rocket engine solid fuel (SPRM) with a telescopic extendable nozzle with a discrete-mass approach. We developed an automated algorithm for computing the parameters of the study of stress-strain state (SSS) of the sliding nozzle with the forward and reverse shock-pulse action. The dynamics of elastic- wave processes for different values of the kinetic energy nozzle nominated. As part of the numerical experiment we obtain estimates for the distribution of safety factor nozzle strength.
