TOICA

Thermal Overall Integrated Concept Aircraft

Toica logo

The European TOICA project intended to radically improve the way thermal studies are performed within aircraft design processes. Its goal was 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 is developed and exploited in a Behavioral Digital Aircraft environment that is 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.

Partner

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

Research Funding

The research leading to these results has received funding from the European Union Seventh Framework Program (FP7) under grant agreement No. 604981. The project started in Sep. 2013 and ended in August 2016.

DynStart - Start-up and Transient Behaviour of Power Plants

The joined research project "DYNSTART: Start-Up and Transient Behaviour of Power Plants" investigated the capabilities of power plants with and without CCS technologies to provide residual loads in future energy markets. The study points out potentials and limits of operation at extra-low-load and during start-up and shut-down. Besides the process-technical aspects of the issue modern MIMO control strategies are focused in the study as can improve the power plants' abilities to fulfil future grid requirements.

The Modelica library ClaRa

The Modelica library ClaRa was improved during the research project. ClaRa stands for Clausius-Rankine cycle. The source code of the library was completed by new components and improved with respect to its numerical robustness and validity in special operation modes (start-up, shut down, downtime).

Nakulek

Nakulek - Model-based design and analysis of a natural circulation for cooling of aircraft systems

Nakulek logo

In this aviation research project an innovative cooling system for high-temperature heat loads in aircrafts was developed. Power electronic components shall be cooled by means of a natural circulation and phase change material (PCM). XRG innovated straightforward simulation techniques to allow a model-driven system development. Thus, the models can be used to optimize the design of the system with regard to essential parameters like weight, power consumption, aerodynamic drag and integration space. New model libraries provide models for robust simulation of natural circulation using sustainable refrigerants. Both, 1D and 3D (CFD) models allow either a system or component simulation for two-phase flows.

Partners

In this joint research project XRG Simulation cooperated with ZAL GmbH (Hamburg’s Center of Applied Aeronautical Research) and the institute of Technical Thermodynamics of Hamburg University of Technology.

Research Funding

The research project Nakulek was supported by the Federal Ministry of Economics Affairs and Energy (number 20Q1519B) and started in July 2016 and terminated end of June 2020.
