Abstract :
With respect to hypersonic re-entry vehicle, by applying the Newton-Euler´s method, the six-degrees of freedom(6-DOF) dynamical equations of moving mass for a re-entry vehicle are derived and the control mechanism is analyzed according to the dynamical equations. Under the environment of Matlab, the 6-DOF trajectory simulation is presented based on the dynamical equations considering the earth´s rotation and non-spherosomes factors, the cross-range and down-range of the impact point cause by lateral movement of the moving masses are computed by simulation and the results validate the feasibility of moving mass control.
