Abstract: Using a system of two mass points joined together by a weightless elastic dissipative thread as the simplest model of elastoviscous system, we investigated the evolution of rotational motion in the gravitational field. When such a system moves in a Keplerian orbit, energy dissipation in the thread material causes the system to tend to the position with the energy of relative motion. Under the effect of dissipative forces the energy loss decreases for both the orbital motion and the relative motion, the orbital eccentricity increases, and the system rotates in the direct sense. �сорів, вентиляторів, турбін), які застосовуються в космічних енергетичних установках, а також в народному господарстві. За допомогою оптичних методів вперше визначені типи нестійкостей, які виникають у потоці. Одержано експериментальні залежності для визначення початку ламінарно-турбулентного переходу та його закінчення.
