Aerodynamic Modeling, System Identification and Analysis of Iced Aircraft Configurations

Performance-Based Ice Detection Methodology

“…2, whereas there is only a minor influence on the aircraft's lift behavior in the left plot. Similar results [28] are given in Fig. 3 for a leading edge icing case, but in contrast to Fig.…”

“…2 for the run-back ice case of Ref. [28]. The significant drag increase due to ice accretion is visible on the right plot in Fig.…”

“…Based on the knowledge published on these modeling approaches [24][25][26][27] a novel way to model aircraft icing effects including a validation of the developed model formulation with flight test data was given in Ref. [28] and demonstrated using real flight data of a light business jet for two different artificial ice shapes [28]. The model formulation used was able to represent well the effects of icing on the test aircraft.…”

“…Based on the information about the aerodynamic degradation in Ref. [28] and the results in Refs. [12,[24][25][26][27] and Ref.…”

Inside the Virtual Test Aircraft (VIRTTAC) Benchmark Model: Simulation Architecture

“…accumulation as well as a de-icing can be triggered by the user whereas the details about the degradation itself are part of the closed model to allow a fair and realistic test of new developments like detection algorithms or robust flight controllers. The corresponding knowledge about the expectable effects and a realistic amount of degradation is derived from previous icing research at DLR [46,47] where high-quality simulation models were identified from flight data.…”
