Open Innovation/Sagitta – Implementation and Validation of a Real-Time Flight Dynamics model for Simulation, Integration Testing and Pilot Training

Kurzfassung

The OpenInnovation/Sagitta project has its focus on the contribution of innovative technologies for the application within the UAV sector. Therein a number of research facilities and academic institutions – under the lead management of Airbus Defence and Space – are working together in order to resolve relevant questions: The Technical University of Munich (TUM), the University of the Armed Forces Munich (UniBW), the Technische Hochschule Ingolstadt (THI) and the TU Chemnitz (TUC), as well as the German Aerospace Center (DLR, being involved with a total of three institutes). Within project scope, a scaled demonstrator UAV aircraft has been designed for in-flight verification capabilities of the derived scientific project results. Aside the overall integration tasks in advance of its maiden flight, the aircraft is currently undergoing intensive simulation and integration testing activities on various levels. Within this paper, an overview of the general setup for these activities is given - specifically focusing on the required flight dynamics model (FDM) which depict the actual physical properties of the aircraft. Furthermore the respective implementation challenges due to project requirements are discussed in detail. Finally the performed validation tasks are described - as required to achieve clearance of the FDM for formal testing.
