Parameter Estimation

Flight simulators can be used for a variety of applications. One of the most widely known application of aircraft simulators is in pilot training. Pilots can train a variety of tasks in flight simulators, from basic procedures and aircraft handling to managing system failures such as an engine malfunction. Besides the training of pilots, another application of flight simulation for example is in the development and tuning of flight control systems (autopilots, stability augmentation system, etc.) or in the prediction of performance and handling qualities during the development of a new aircraft.

The basis of aircraft simulation is a mathematical description, i.e. the model of the system to be simulated. Depending on the application, this model usually includes multiple sub-models, for example an aerodynamic model, a model of the propulsion system, a model of mass and inertia, a model of the landing gear and the ground interaction, and many more. Key to a good model is the correct evaluation of the specific parameters that define the dynamic behaviour of the aircraft.

Project Description

The Centre for Aviation has experience in developing aerodynamic models from flight test data. This includes:

  • definition of the manoeuvres and test points of the flight test campaign,
  • specification of the instrumentation,
  • support during the flight testing,
  • flight test data processing, filtering and calibration,
  • flight path reconstruction (data compatibility check),
  • aerodynamic parameter estimation, and
  • validation of aerodynamic models.

The Centre for Aviation has experience with state-of-the-art parameter estimation methods and can support the specific needs of the industry or research partner. Support for EASA and FAA FSTD qualification can be provided.
