Development of response surface models for estimating operational requirements of reusable launch vehicles

摘要

This paper describes the development of response surface models for estimating reliability and maintain-ability (R&M) characteristics for a range of reusable launch vehicle concepts. Design-of-experiments methods are utilized to sample the design space efficiently and build polynomial approx-imation models. These models enable the rapid estimation of operational resources early at the design phase for lifecycle cost analysis and systems level design integration of operational requirements.
