Asymptotic analysis of atmospheric descent of the Martian asymmetric probe before and after the heat shield undocking

The aim of this paper is to compare the regularities of the angular velocity variation of an asymmetric Martian probe before and after the separation of the heat shield. The asymptotic analysis of angular velocity values is based on the application of the non-resonant scheme of the averaging method. The condition for ensuring the non-resonant rotation of the probe is investigated. The condition for the non-resonant rotation of the probe in the vicinity of the resonance is also analyzed. The obtained regularities of the change in the angular velocity are confirmed by the results of numerical simulation.
