The NATO STO AVT-201 Task Group on Extended Assessment of Stability and Control Prediction Methods for NATO Air Vehicles: Summary, Conclusions and Lessons Learned

Abstract

This article presents cross-comparisons of the results obtained within the NATO STO AVT-201 Extended Assessment of Reliable Stability & Control Prediction Method for NATO Air and Sea Vehicles Task Group. The results of five participating organizations and six different CFD solvers are compared to the available wind tunnel data from the DNW-NWB wind tunnel obtained at low Mach number, for both static and dynamic cases. The comparisons help to find commonalities and disparities in the CFD predictions of the aerodynamics of a generic UCAV, SACCON, and point to areas where CFD is challenged by non-linear aerodynamics ow prediction. These comparisons help to show where the modeling and simulation of novel aircraft platforms in the earliest stages of design development can contribute to a more successful design process by determining diffcult non-linear aerodynamics and helping to change the design prior to the later stages of the design process.
