Представлено результати числового аналізу аеропружних характеристик лопаткового вінця ротора останнього ступеня парової турбіни 220 МВт з довжиною лопаток 1200 мм. При аналізі використовувався метод розв’язання зв’язаної задачі нестаціонарної аеродинаміки та пружних коливань лопаток, який дозволяє прогнозувати амплітудно-частотний спектр нестаціонарних навантажень і коливань лопаток в потоці в’язкого газу. Результати розрахунків показали відсутність флатеру та автоколивань на перших п’яти власних формах коливань лопатки у номінальному режимі роботи парової турбіни.
