Increasing thermal loads are found to be an operationally limiting constraint for military air, land, and sea vehicles. Electrical power levels have continued to grow exponentially with nearly 70% of the power eventually dissipated in the form of waste heat. Often, thermal problems surface only after a new system has been fielded and will tend to force restrictions on the platform’s operational capabilities.
AVT-226 is assessing thermal model validation methodologies in order to strengthen design practices for future military platforms. The objective of this task group is to understand and quantify the uncertainty in thermal models through experimental validation of a representative thermal management system.
Validation of component models for steady state and transient environments will be assessed through the development of a common test bed. Available thermal modeling and testing capabilities within NATO countries will be indentified. The team will compare experimental, analytic, and numeric approaches to model verification and validation. Methods for quantifying component interactions in subsystem assemblies and robustness requirements for component models to off-design conditions and installation variability will also be investigated.
