The ISSI team will develop and convert technologies with commercial potential to provide affordable access to space for advanced space transportation systems/aeronautics through a modular multi-discipline framework system which performs vehicle/propulsion design to operation, that reduces significantly life-cycle cost.The Phase I objective is to establish and demonstrate the feasibility of developing a modular framework system capable of interfacing and integrating the multiple computer based modeling, simulation and analysis systems presently being applied to RBCC ETO vehicle development. The objective of Phase II will be to provide a working system ready for commercialization in Phase III.The effort consists of further evolving GIT's "IMAGE" modular framework system to interface and integrate existing industry "standard" RBCC ETO vehicle/propulsion design and performance analysis models. The framework system will be extended to incorporate the modified GIT cost module to demonstrate cost based on an activity based economic methodology.The results will be a prototype of an expandable, modular framework system capable of supporting multi-disciplinary design/cost optimization and being extensible to the remaining phases of the full life-cycle of RBCC engine propelled ETO vehicles and the general problem of the development of complex technological systems in the industrial, utility and commercial marketplaces.7. Potential Commercial Application(s): The commercial potential is in the launch vehicle, propulsion systems and related areas: commercial, and space and defense corporations LV's used in supporting the burgeoning communications, TV, cellular phone satellites industries. NASA and DoD, especially the AF with its Military Space Plane or Trans-atmospheric Vehicle (TAV), will be potential users of the system and technology. This will include the growing small business entry to the launch vehicle and propulsion markets.This proposed system with the enhanced IMAGE and activity based cost model, will be applicable to not only airbreathing and rocket based vehicles and engines, but any aircraft or spacecraft system; in general the proposed methodology is applicable to any complex system. At the present time, the commercial need for the proposed system and activity based cost model is expanding for the government, military and commercial entities is at hand. The proposed products provide for commercial spin-offs in the following technology areas: graphic modeling in simulated real-time, Internet application for graphical inventory techniques applied to cost model, Internet collaborative research capabilities, post-flight data bases and analysis techniques, configuration management, multi-disciplinary design optimization and system modeling. Other commercial applications are identified in Part 6.
