The study of a passage through resonance of a spacecraft with variable mass asymmetry when descending with small angles of attack in the atmosphere of Mars

The motion of the spacecraft with small aerodynamic and mass asymmetry in the rarefied atmosphere of Mars is considered. The control of the angular velocity of the spacecraft is performed by changing the values of the mass asymmetry. We estimate the passage of a mechanical system to the resonant oscillating region when applying a predetermined control law mass asymmetry value in the case of small values of the angle of attack. We compare simulation results obtained in the management of value of the mass asymmetry implemented using sinusoidal and exponential laws. It is shown that the exponential law allows for large initial values of the mass asymmetry, providing non-resonant motion of the spacecraft.
