Abstract

Работа посвящена повышению эффективности Ð¼Ð°Ð»Ð¾Ñ€Ð°ÑÑ Ð¾Ð´Ð½Ñ‹Ñ Ñ‚ÑƒÑ€Ð±Ð¸Ð½ с осесимметричными соплами за счет совершенствования ÐºÐ¾Ð½ÑÑ‚Ñ€ÑƒÐºÑ‚Ð¸Ð²Ð½Ñ‹Ñ Ð¸ Ñ€ÐµÐ¶Ð¸Ð¼Ð½Ñ‹Ñ Ð¿Ð°Ñ€Ð°Ð¼ÐµÑ‚Ñ€Ð¾Ð² Ð¿Ñ€Ð¾Ñ‚Ð¾Ñ‡Ð½Ñ‹Ñ Ñ‡Ð°ÑÑ‚ÐµÐ¹ соплового аппарата и рабочего колеса. Рассматриваются вопросы реализации обратной «стреловидности» лопаток рабочего колеса, положительного кинематического «навала» и профилированного корневого обвода рабочего колеса, влияния ÑÑ‚Ð¸Ñ ÐºÐ¾Ð½ÑÑ‚Ñ€ÑƒÐºÑ‚Ð¸Ð²Ð½Ñ‹Ñ Ð¼ÐµÑ€Ð¾Ð¿Ñ€Ð¸ÑÑ‚Ð¸Ð¹ на эффективность Ð¼Ð°Ð»Ð¾Ñ€Ð°ÑÑ Ð¾Ð´Ð½Ñ‹Ñ Ñ‚ÑƒÑ€Ð±Ð¸Ð½ исследуемого класса.
