In the early stages of aircraft design, a scaled model of the aircraft is installed in a wind tunnel for dynamic semi-free flight to approximate real flight, and the test data are then used to identify the aerodynamic parameters. However, the absence of ...

In this paper, unsteady motion tests of a lateral jet adjusting an air vehicle?s attitude are carried out. Curves of pitch moment amplification factors (KM) for a lateral jet versus angle of attack (a) are obtained using a wind tunnel free-flight test te...

The wind tunnel virtual flight test realizes the dynamic semi-free flight of the model in the wind tunnel through the deflections of the control surface and uses the test data to identify the aerodynamic derivatives. The difference in dynamics between th...

With the increasing bandwidths of servo control systems and decreasing mode frequencies, aeroservoelastic (ASE) stability evaluation has become an essential part of flight vehicle design. However, the theoretical method is limited by the modeling errors ...
