Simulation of loads on a flexible aircraft during a gust passage.
One of the research areas of the Institute of Flight Systems is the development of control systems to reduce loads that occur during gusts or in turbulence. The picture shows the simulation of a gust encounter with a flexible, high-winged aircraft. The simulation illustrates the wing bending moment occurring during the gust encounter and the moulding of the aircraft.

The expert group on Modelling and Simulation deals with the development of simulation models for aircraft. This can be achieved by the so called system identification, utilising data from flight experiments or wind tunnel tests. In purpose of efficient analysis of measurement data, the group develops software tools that offer flexible opportunities to customise the tools to the specific needs of individual application.
The extracted simulation models can be used in a variety of purposes, e.g. in flight simulators, for flight performance or flight characteristic evaluations, for the development of system control techniques or to validate external models within the flight tests. Thus, the modelling and simulation of dynamic systems is the basis for many of the departments’ research projects and allows various opportunities to cooperate with the industry.
Effects, like aircraft icing, stall and elastic degrees of freedom are additional research topics. In order to optimise future flight testing programs, the group is working on online-techniques for system identification that allow data analysis meanwhile the flight experiment is running.
