Flight Dynamics Modeling and Aerodynamic Parameter Identification of Four-Degree-of-Freedom Virtual Flight Test

What is it about?

Compared with the forced motion in a conventional wind tunnel test, the virtual flight test can achieve dynamic semi-free flight of the model in the wind tunnel by manipulating the rudder deflection. In this paper, a new 4-DOF virtual flight test device is established, compared with the 3-DOF wind tunnel virtual flight test with rotation around the center of mass, the model adds vertical motion, enabling it to simulate free flight more realistically.
