The equations above only target the relative wind angle and the slip angle.
The terms in Equation (10) consist of the relative wind angle component, relative wind angular velocity component, slip angle component, and yaw angular velocity component.
For these nonlinear changes in the relative wind angle [[beta].
we] is assumed to be the average value in the vehicle range of the nonlinear relative wind angle [[beta].
From these results, even if the relative wind angle changes in a nonlinear fashion, it can be treated as a linear variable in accordance with Equations (18) and (20).
The aim of test (c) is to obtain aerodynamic force fluctuations in accordance with changes in the relative wind angle by changing the individual settings of the crosswind fans.
ij] is the conventional static aerodynamic forces component that is proportional to the relative wind angle, and [c.
In addition, although this aerodynamic forces model is nonlinear, it was linearized by assuming very small relative wind angle fluctuations from the average relative wind angle [B.
Y[beta]w]) proportional to the relative wind angle.
The relationship between the vehicle motion and the relative wind angle fluctuations and aerodynamic forces was modeled and numerical expressions applicable to all vehicles were defined.
