The Institute of Flight System and Automatic Control operates a fixed-based research flight simulator. The Institute's research groups use this simulator to validate their concepts together with the end-user, active civil airline and test pilots. The simulator follows a modular concept in which hard- and software components can easily be exchanged and extended. The flight simulation software and the simulation environment have been developed at the Institute, allowing the continuous extension and adaptation to evaluation specific requirements.
DA 40-180 Simulator
Besides operating a flight simulator of a transport category airliner the Institute of Flight Systems and Automatic Control owns and operates a general aviation category flight simulator. This smaller simulator is based on a FNTP produced by the Trebur, Germany, based company Diamond Simulation. It represents the single-eninged Diamond DA 40-180 Diamond Star sport and touring airplane. This aircraft is in widespread use in the general aviation community and often is equpped with modern IFR-capable avionics. Consequently the simulator is also provided with the same systems, such as a Garmin G1000 integrated avionics suite.
The Test Vehicle for Navigation
The institute owns a test vehicle for use as a mobile testing platform, which could hold very different sensors. At present, the testing vehicle is equipped with:
– a highly accurate geodetical GPS receivers as well as numerous commercially available GPS receivers
– a data link to our own mobile GPS reference station
– a very precise avionic initial navigation system (INS)
– a data link surveying the air traffic situation on airports
Asynchronous Motor Test Rig
For the validation of our diagnosis and prognosis methods, a test rig for the generation of bearing fault data is applied. The main part of the test rig is an asynchronous motor. By means of different loads, like radial force or electric current, which influence the test bearing, different fault cases are simulated and diagnosed. The progressive damage state of the bearing is furthermore the starting point to determine the remaining useful lifetime by means of data-based prognosis approaches.
Unmanned ground and aerial vehicles (UGV/UAV) are already used for many different purposes. Not only for military forces, but also for public authorities and organisations dealing with civil protection and for monitoring tasks they became an important working aid.
The research about unmanned vehicles unifies many topics that belong to the core competencies of the institute: robust control of such a high dynamic system, the problem of localization and navigation, integrating unmanned vehicles in the public airspace and human-machine-interaction with respect to aviation.
As demonstrators two ground and several flying vehicles have been built and successfully tested. The quad-rotors have the capability to take off and land, to hover and to follow a predefined trajectory autonomously. They are used for research on cooperative control of swarms and collision-free navigation in unknown environment.
