In view of the big complexity of a problem, research of their work demands application of the modern methods based on use of the com­puter. Thus discrete models, as in the best way adapted for such discrete device, as represent the computer, are very interesting. In the article the discrete model of a gas-turbine engine disk with blades is offered, allowing to take into account winding oscillations of blades together with movement of a disk. Use of symmetry of system allows to reduce a task about oscillations of system with the big number of degrees of freedom to a task with two and three degrees of freedom . All mode shapes of oscillations of the system are describedruроторные системыколебание системывектор смещенийвектор амплитудвенец лопатокузел газотурбинного двигателяArticle
