Framework for Aircraft Cost Optimization Using Multidisciplinary Analysis

This report summarizes the work that has been carried out as part of the Flapless Air Vehicle Integrated industrial Research project, a five-year research program looking at technologies for future aircraft. A novel classification of aircraft product definition is used, and a framework to estimate the life cycle cost of aircraft using the product definition is presented. The acquisition costs are estimated using a hierarchical structure and a discrete-event simulation model is used to estimate the maintenance and operation costs. The cost models developed are integrated into the conceptual aircraft design process to facilitate the comparison between different configurations. The usage of the life cycle cost framework as a decision support tool is outlined by using the cost models to perform multidisciplinary analysis and optimization studies.
