Requirements for computer generated aerodynamic models for aircraft stability and control analysis
For aircraft stability and control analysis tabular aerodynamic models are considered in this work, with computational fluid dynamics being the source of data. These tables are evaluated for an aerofoil case for a number of conditions including the presence of shocks and/or stalled flow. It is seen that for a large range of conditions the tables are sufficient to predict the forces and moments but the quality of the prediction is degraded when complex flow regimes are encountered due to history effects. The use of dynamic derivatives to introduce the rate effects is shown to be insufficient in these regimes.

Abstract
For aircraft stability and control analysis tabular aerodynamic models are considered in this work, with computational fluid dynamics being the source of data. These tables are evaluated for an aerofoil case for a number of conditions including the presence of shocks and/or stalled flow. It is seen that for a large range of conditions the tables are sufficient to predict the forces and moments but the quality of the prediction is degraded when complex flow regimes are encountered due to history effects. The use of dynamic derivatives to introduce the rate effects is shown to be insufficient in these regimes.
