Innovative Methods to Determine Thermal Capacity of Remaining Fuel Quantity Heat Sink in Real Time

The primary objective of the proposed effort is to develop a real-time thermal capacity algorithm. 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.
