Analysis of emerging disturbing factors on the descent vehicle with inflatable mechanical devices during the descent stage

Abstract The movement of asymmetric descent vehicles, in contrast to the movement of symmetrical landing vehicles, has a number of features. The main of them consist in the emergence of such dynamic phenomena as progressive self-rotation, vibrational-rotational resonances, nutation-precession instability, auto-oscillations, and others. In this paper, the entire landing trajectory is divided into main stages of movement, and then an analysis of some of the most unfavourable variants of movement at each stage is given. The conclusion is about the worst options. This must be taken into account when designing such descent vehicles with inflatable structures.
