Kurzfassung
To characterize changed aircraft dynamics due to icing a Delta-model extension is analytically derived and its parameters are estimated. This model extension is formulated as a separate module in the aerodynamic part of the aircraft simulation and can be used in existing simulation models. Within a cooperation of DLR and EMBRAER flight data of a light business jet with different ice accumulation cases are used to identify the parameters of a clean and a Delta-model describing icing effects. The Delta-model parameters are interpreted with respect to the aerodynamic degradation caused by icing. An analysis of different asymmetric icing cases is performed using the identified Delta-model. Trimmed flight conditions deliver an information about the maximum expectable additional icing induced moments and the necessary control surface deflections compensating the disturbance. The ability to cover various icing effects is shown by dynamic simulations reducing local icing effects similar to ice shedding situations in flight.
