Generic simulation models are essential for the evaluation of new concepts, processes and methods in the field of aviation and transport and are therefore an essential part of our research.
Three institutes and three simulators - that was the challenge in the iUSIM project, which the DLR institutes of flight guidance, of transportation systems and of software technology faced. In this video, the institutes show with a use case from rescue mobility the synergies of the joint cooperation and the potential in the coupling of simulators. The project focussed on the creation of shared databases and tool chains for cross-institute joint simulation.

Development of a multimodular simulation infrastructure in the iUSIM project
Three institutes and three simulators - that was the challenge in the iUSIM project, which the DLR institutes of flight guidance, of transportation systems and of software technology faced. In this video, the institutes show with a use case from rescue mobility the synergies of the joint cooperation and the potential in the coupling of simulators. The project focussed on the creation of shared databases and tool chains for cross-institute joint simulation.
The DLR Institutes of Flight Guidance, Transportation Systems and Software Technology each have in-depth knowledge and expertise in various simulation technologies and possibilities. In order to reduce the workload in future projects, we are using our synergies to develop joint visualisation concepts. Our long-term goal is to develop a cross-institute, multimodular simulation infrastructure and to integrate existing simulators into it. The technical and methodological requirements for this were realised in joint cooperation. The focus here was on creating shared databases for simulation elements such as models, sounds and traffic routes.
Tasks
The concept for the development of a multimodular simulation infrastructure includes the following tasks:
Harmonise development tools and simulation environments to enable the exchange of 3D environments
Development of joint infrastructures and libraries that can be used across institutes
Develop and implement data exchange formats and infrastructures for cross-institutional network simulations
Develop concepts for the realistic design of simulations and build technological building blocks (3D models, sounds, design of the 3D world)
The results of the collaboration are tool chains for developing simulation objects and libraries for shared simulation environments that can be used as a whole or in parts by each institute. Such environments can, for example, be bundled into a large virtual map containing different components such as houses, railway stations, airports, bodies of water and green spaces. In addition, the concept of a common communication infrastructure for carrying out network simulations is being developed. Suitable tools will be developed for converting existing models (e.g. 3D objects, terrain data) into the software solutions of the individual institutes. An application case will be used to demonstrate that two different plants can use a joint simulation environment. In addition, a qualitative study was conducted on the social acceptance of unmanned aerial vehicles in a pedestrian simulator, in which the developed environment was used for the first time. The results of the demonstration and the study serve as a basis for publications. They also form a basis for future project acquisition activities.
Perspective
The development of a joint tool chain will also improve co-operation between the institutes in the future and reduce development costs. Existing modules can be exchanged more easily and duplicate developments in the individual institutes can be avoided. This can reduce costs on the one hand and increase quality and acquisition opportunities on the other. In addition, the joint work makes it possible to analyse the interaction of several road users (airborne and ground-based) in comprehensive network simulations. In this way, we can continue to do justice to research into increasingly complex traffic scenarios in the future.
The expected work results are seen as an essential basis for future simulation studies and for further projects in the field of urban mobility and therefore represent an essential contribution to aviation research at DLR.
The work is a continuation of the collaboration initiated within the framework of the NGC-KoFiF and City-ATM projects.
