With the increased complexity of modern tactical aircraft, more of an effort is being made to produce accurate and informative models of the various systems and subsystems. The subsequent models can then be coupled together, to produce a complete model of the tactical aircraft. Due to the variance in model time scales and the potential complexity of loading profiles, the models must be able to capture the transient nature of the subsystem performance with sufficient accuracy to allow interfacing between different types of subsystem models.
Development of an accurate, transient thermal model offers both unique challenges and benefits. A vapor compression system operates over a variety of time scales, from the relatively fast dynamics in the system pressure to the slow dynamics in the thermal distribution. Additionally, vapor compression systems may have a variety of optional components (e.g. regenerative heat exchangers) while also interfacing with different types of thermal sinks (e.g. liquid versus gaseous). However, it is worthwhile to address these challenges for the benefits that are offered by modeling the vapor compression system. Not only can the models be used to verify that an existing system can tolerate the required heating load, but controllers can be applied to the model to optimize model performance and increase the potential maximum heating load. Creation of predictive models is necessary to maximize the model’s ability to address various heating scenarios.
