Influence of shape of blades upon descent of a finned body in media
Descent of a finned body in resisting medium is studied. Two different kinds of blades are discussed: disk and rectangle. Trajectories of a center of mass of a body are analyzed. Two kinds of steady regimes are revealed depending on pitch angles of blades: descent with autorotation and descent with zero angular speed of the body. Dependence of speed of the center of mass on values of pitch angles is described.
