The paper analyzes rotational motion of an aerial vehicle, which inertia resultant moments are not equal to each other. An ash seed served as the prototype of such an aerial vehicle, as the seed flies in the autorotation mode. Mathematical model of the aerial vehicle angular motion was compiled to study its movement. Mathematical model equations were solved by the 4th order Runge—Kutta Method using the developed software. Analysis of the results obtained made it possible to make a conclusion about the influence of the inertia moments magnitude on the transient process nature. The resulting mathematical model could be applied in studying the descent vehicle motion controlled by the payload rotation method. As a result of altering the payload angular position, as well as of deformation of the descent vehicle flexible elements, similar mass distribution could be obtained. Thus, research is being carried out to analyze conditions, under which the aerial vehicle enters the autorotation mode, and whether this effect could be applied or eliminated in technology.
