Abstract:

The objective of the proposed effort was to evaluate the U.S. Air Force sponsored Vehicle Integrated Thermal Management Analysis Code VITMAC for 1 including an optimizationexpert systems architecture for analyzing thermalfluid network configurations at the component, subsystems, and system level, and 2 coupling VITMAC with engine performance and cycle codes to provide a more integrated mission analysis capability as well as more accurate definitions of thermal loads. This effort resulted in the inclusion in VITMAC of a flow condition optimization method which automatically determines component operation to match user-specified thermal circuit operating conditions. This was the first step in implementing a plan for a multi-level optimization method which was developed for a Phase II program. Various engine performance and cycle models where evaluated which resulted in the recommendation that VITMAC be linked with APLs RJPA ramscramjet engine performance code as well as NASAs CEA rocket performance model and NNEP turbine engine cycle code. Finally, a plan for commercializing VITMAC was developed which includes 1 enhancing the graphical user Interface GUI to make it more user friendly and robust, 2 organizing workshops to provide industrial experts with influence on and knowledge of VITMAC capabilities, 3 providing end-user support and training and, 4 developing a market plan for transferring the technology for aircraft and non-aircraft applications.
