Device-Oriented Modeling and Simulation in Aircraft Energy Systems Design

Airframers realize that global optimization of the entire aircraft is the only remaining way to achieve substantial improvements in the total aircraft package. Therefore, a methodology for the design of globally optimized aircraft energy systems is introduced and implemented for air conditioning and cooling systems. It allows establishing energy-optimal open-loop control concurrently with optimal aircraft energy system architecture. To support this development, the underlying equation-based modeling language is developed further in two regards, the mathematical and numerical formulation of convective transport, and the initialization of large differential-algebraic equation systems.
