| Abstract: | When the derivative of the coordinate unit vector doesn't equal zero, the kinematical and dynamical equations of aircraft can be expressed much more explicit and concise according to establishing the conversion matrices and defining differential equations of the coordinate. The conclusion contributes to understanding the relationship of the moving coordinate and the stationary one in the time domain. The mathematic expression is convenient to be realized with MATLAB language, which is helpful to model and simulate the aircraft. |
