Taguchi's approach for reliability and safety assessments in the stage separation process of a multistage launch vehicle

摘要: This paper presents in brief the formulation for lateral and longitudinal dynamics associated with separation pull out of an ongoing functional stage from spent a multistage launch vehicle using motors as jettisoning system. Taguchi method is employed to understand influencing parameters process. It possible minimize number Monte-Carlo simulations (MCS) by Taguchi's orthogonal array. Statistical analysis has been carried identify probability distribution function (PDF) reliability safety assessment The tolerances on time, relative velocity, gap clearances between separating bodies are taken into account while examining non-occurrence collision bodies. Lateral gap/dynamic clearance stages found be very vital aspects. study clearly demonstrates applicability capture essential simulation results approach followed this will useful dynamic behavior during process vehicles.
