Abstract
Purpose The focus of this paper is on reliability and availability design goals. It aims to provide toplevel estimates of the safety and maintainability of future spacecraft systems. Designmethodologyapproach The developed design tool uses basic reliability principles to estimate the probability of a safe mission and the need for repairsreplacement during ground processing, before launch and start of mission, based on the characteristics of the vehicle's main systems the number of subsystems, the mean time to repair, and the per subsystem average reliability. Findings A simple reliability, maintainability and safety model is developed to support the toplevel design process of future space transportation vehicles. It also describes how the developed design tool uses various sensitivity analysis functions to improve design decisions. Originalityvalue The goal of the developed tool is to provide engineersvehicle developers during the early stages of design with a tool that demonstrates the effect on maintainability of improving component reliability and reducing the number of components.
