Descent Vehicle Movement Control by the Angular Position Change Method Payload

An analysis of the rotational motion resulting from the control of the descent vehicle is presented in the paper. The descent vehicle is controlled by the method of shifting the center of mass, which occurs due to a change in the angular position of the payload. The analysis of rotational motion consists in revealing the peculiarities in the motion of the descent vehicle controlled by the above method. To carry out this analysis, a mathematical model of the rotational motion of the descent vehicle has been compiled in this work. Modeling of the angular motion was performed using the developed software that implements the 4th order Runge-Kutta method. The simulation results are presented in the form of graphic dependencies, which include the trajectory of a point on the surface of the descent vehicle, as well as the hodograph of the angular velocity vector in a moving coordinate system. Based on the results of the research, conclusions were drawn about the features of the rotational movement during control, as well as the possibility of using this control method.
