Abstract
Abstract : The primary objective of this Phase 1 effort was to demonstrate the feasibility of integrating a set of simulation based design and performance evaluation tools linked through a generalized, common database system that supports rapid assessment of space vehicle concepts. An end-to-end, simulation based development approach, featuring rapid prototyping and integrated development tools, can enable a small team of engineers to evaluate space vehicle concepts, support development, and validate performance for space vehicles. This set of tools can range from simplified concept definition and assessment tools to non-real time and real time high fidelity simulations. This effort has focused on demonstrating how the integration of a subset of tools can support rapid design and performance assessments of reusable launch vehicles. Analytical tools considered in this Phase included a vehicle sizing tool, several trajectory design applications with various levels of guidance optimization and hi-fidelity 6 Degree of Freedom (6DOF) simulation environment. These tools have been integrated with an open architecture common database system, utilizing our Integrated Development & Operations (IDO) process. The IDO process directly supports all system life cycle phases, starting with conceptual design, and evolving through preliminary design, detailed design, and finally operations of space vehicle system. This effort focused on implementation of the Integrated Database System (IDS), and application interfaces to a selected subset of these Phase 1 design tools, utilizing a generic RLV system design to demonstrate the benefits of data capture, configuration control and consistency across all tools under study. These three elements (simulation based R&D tools the IDS, and the IDO process) comprise what USL calls the Integrated Development and Operations System (IDOS). The project culminated in an on-site feasibility demonstration and briefing.
