The algorithm will be capable of quantifying remaining thermal capacity providing an assessment of mission capability. The algorithm will be derived from detailed models of the thermal management system and will be designed to adapt to the changing environmental and mission conditions. Initial development and testing in the base effort will leverage previously developed thermal models for proof-of-concept, with migration to higher fidelity representations in the proposed option effort. The implementation of the algorithm will be consistent with current diagnostic and hardware capability on-board modern survivable aircraft. Benefits: As heat generation increases and ability to reject heat decreases, thermal limitation on-board modern survivable aircraft reduce mission capability. The direct benefit of the Phase I effort will be the development of a real-time thermal capacity algorithm capable of quantifying remaining thermal capacity. By providing real-time feedback, mission alterations can be made that allow for successful completion of primary or secondary objectives while maintaining thermal constraints. The preliminary development in the Phase I base effort with high-fidelity integration in the option effort should enable successful transition to a flight test validated approach in the Phase II.
