Huntsville Sciences Corporation (HSC) proposes to develop artificial intelligence (Al ) analogs for rocket exhaust nozzle/plume characterization and plume induced environment predictions for launch vehicle, missile and spacecraft design. Plume characterization and plume induced environment predictions (convective and radiation heating, flow separation, impingement forces, heating and contamination, acoustics, aerodynamics etc.) is as much an art as a pure engineering process. There are a multitude of models that are available to make predictions but each of the tools available to make predictions requires levels of expertise that are only attainable after years of experience in using them. The development of Al analogs for use with and in evaluation of the results of these methods will insure that the expertise that has been so heavily invested in will not be lost. The application of artificial intelligence to plume induced environment effects on vehicle design is innovative in that it has not been previously applied to reduce the time and cost to design and develop new transportation systems. The Phase I effort will develop and demonstrate the application of artificial intelligence in plume characterization and develop the architecture for the Phase II overall environment Al induced tool. The Phase II effort will develop the Al analogs for environment prediction and develop the complete plume environment prediction system. The initial use for this technology is the specification of design environments for aircraft, luanch vehicles, missle and spacecraft at significantly less time and expense than are currently possible. Huntsville Sciences Corporation envisions the Phase II product to be widely accepted by industry and as such an easily marketable tool to government and industry for flight vehicle design. By packaging the plume and plume induced environment methodologies with an Al system, it will be easy to demonstrate and market these codes based on their capabilities and the cost savings that can be achieved.
