TOICA – Thermal Overall Integrated Concept Aircraft


The European TOICA project intends to radically improve the way thermal studies are performed within aircraft design processes. Its goal is to create a platform for collaborative modeling and simulation of the thermal behavior of aircraft airframe systems, equipment and components. The resulting overall thermal aircraft architecture will be developed and exploited in a Behavioral Digital Aircraft environment that will be designed to the needs of thermal architects and experts.


The efficient treatment of thermal energy on board plays a significant role in the design of future aircrafts due to higher heat loads caused by in-flight entertainment systems, new electrical driven power and actuating systems, use of composite materials and last but not least environmental targets to reduce the fuel consumption and emissions. This challenging task can only be achieved by an integrated approach for modeling and simulation of the interaction between all systems. An according tool chain will be developed in this project.

XRG is part of the project consortium consisting of 32 organizations and will work on advanced methods for zonal modeling of aircraft compartments. The XRG goal is to derive efficient models displaying the thermal behavior of air spaces inside the compartment. For this purpose XRG will use suitable model reduction techniques for both 3D (CFD) and 2D/1D (Modelica) approaches. The outcome will result in parametric models for fast simulations.
