The problem of preliminary estimation of the launch vehicle reliability at the stage of selecting its configuration in accordance with specified requirements is considered. The method for solving the problem includes an assessment of the possibility of compensating for rocket engine failures at various ascent stages to deliver a specified payload to the target orbit. The calculation can be performed for a wide range of launch vehicles with tandem and parallel staging, taking into account the possibility of engine shutdown within several stages. The practical significance of the work lies in the possibility of rapid estimation of launch vehicle reliability based on data on the design or operational reliability of rocket engines and the coverage factor of the emergency protection system. The software package operates in the Excel environment and can be modified for a specific task without programming.
