SIMULATION OF THE DYNAMICS OF NON- RESONANT MOTION IN A CONTROLLED DESCENT OF AN ASYMMETRIC SPACECRAFT IN THE LOW-DENSITY ATMOSPHERE

Abstract

Abstract. We consider the problem of implementation of non-resonant motion at descent of a spacecraft with small mass and aerodynamic asymmetries in the low-density atmosphere of Mars. A controllable decrease in the mass asymmetry contributes to implementation of non-resonant motion of the spacecraft. We introduce an analytical control law for the magnitude of asymmetry. The results of numerical simulation of spherical motion of a spacecraft with controllable asymmetry are included.
