Numerical modelling of the stress-strain state of elements of the rocket engine of emergency departure

Abstract

The parameters of the stress-strain state of elements of the rocket engine of emergency departure (REED) under the action of maximum thrust and the internal chamber pressure are determined in the paper. Basing on the design works the most rational design-layout scheme of REED is determined according to criteria of maximum reliability at the lowest cost and providing the required weight of the engine. Within the numerical experiments, distribution of the safety factor for load-bearing structural parts is estimated. Verification of numerical simulation results with the independent data of REED shell tests is carried out.
