| Popis: | A traditional representation of aerodynamic characteristics based on the concept of aerodynamic derivatives becomes inadequate at high angles of attack due to significant dynamic eects generated by separated and vortical flow. The main diculty in an application of aerodynamic derivatives at these conditions is linked with their strong dependence on frequency and amplitude of oscillations. To describe these dependencies the mathematical model for aerodynamic characteristics in the time domain should be dynamic and nonlinear. To capture frequency eects the lateral/directional aerodynamic characteristics are represented in the form of dierential equations and applied for the open- and closed-loop dynamic analysis. |
