Variable-Fidelity Toolset for Dynamic Thermal Modeling and Simulation of Aircraft Thermal Management System (TMSs)

ABSTRACT: The primary objectives of the proposed effort are to enhance, expand, and validate a variable-fidelity transient thermal management toolset. The toolset will be used to model hardware systems in order to validate the approach. In addition, the modeling capability of the tool will be enhanced and expanded to enable modeling of complex thermal management systems. The toolset is designed in a modular, drag and drop library in Matlab/Simulink. Components are developed with a focus on speed, flexibility, and fidelity. The toolset will be provided to a wide user base to ensure that it meets the needs of the modeling community. Documentation will be provided through html help files integrated directly with the Matlab/Simulink help file system. BENEFIT: As cooling concepts on-board present/future military aircraft continue to advance, the need for dynamic vapor cycle system analysis is apparent. The direct benefit of the Phase II effort will be the development of a validated variable-fidelity transient thermal management toolset capable of analyzing dynamic vapor compression cycles including two-phase flow. The toolset will provide the Air Force and aerospace community with the diverse, robust, and accurate analysis capability needed to investigate present/advanced cooling designs of military aircraft. The transition to industry in the Phase II will set the stage for expansive engineering services and support in the Phase III.
