Development of Mission-Design Integrated Framework for Space Launch Vehicles

Abstract

This study describes multidisciplinary design framework development based on system engineering concept for various space launch vehicles to assist aeronautical engineers to successfully design mission and system analysis process. Design framework is composed of five main stages: Requirements, Mission Analysis and Design, System Synthesis and Simulation, Integrated Mission Design, and Reliability and Cost Evaluation. Two databases are established: one is used in the process of data-mining for requirements and another is in the Graphical User Interface (GUI) development of framework. K-Nearest Neighbors (k-NN) and Regression methods are utilized to make the design optimization performed with fast and successful convergence by processing and estimating the data necessary for design optimization. Framework is mainly developed in VB.Net integrating with all discipline modules separately optimized in Matlab. It is demonstrated that much better design can be obtained by using this framework and considering the important design factors from various disciplines.
