Integration of Thermal Management Systems and Quasi 3-D Modeling with Plume Signature Analysis

The impact of liquid fueled missile, thermal management systems on plume signatures, is of critical importance to accurate plume signature modeling. This proposal describes the innovative coupling of an engineering level thermal design tool, VITMAC (Vehicle Integrated Thermal Management Analysis Code) with a Quasi 3-D enhanced Standardized Plume Flowfield Model, SPF-IIIQ3D. In addition, we will explore the use of neural network modeling concepts to provide a fast running plume signature characterization of transient events such as engine start-up and shut-down sequencing. VITMAC is a fast-running PC-based design tool, which models thermal management systems, integrated with propulsion and airframe components subject to various transient heat loads. VITMAC allows for a drop-and-drag construction of complex multi-loop and interacting cooling circuits. When coupled to enhanced plume signature models, the resultant GUI driven, user friendly toolkit, when developed, will be capable of addressing both thermal management system integration and design and its impact on plume signatures.
