Изобретение относится к энергетическим газотурбинным установкам. Турбинная лопатка с тепловой защитой включает основание и перо, на металлический стержень которого нанесено керамическое покрытие. Новым является то, что поверхность стержня секционирована поперечными металлическими ребрами, в зазоры между которыми вложены ориентированные вдоль ребер жгуты из керамических волокон. Поперечные металлические ребра образуют с жгутами замковое соединение. Наряду с жгутами в зазоры между ребрами введен керамобетон с волокнистым наполнителем с образованием секционированной металлокерамической поверхности, на которую нанесен слой ориентированных керамических волокон. Ребра выполнены волнообразными с вогнутостями и выпуклостями, ориентированными вдоль стержня пера. На стержне пера ребра расположены в виде спирали и образованы непрерывной проволокой, профиль которой имеет лыску для установки на стержень пера и углубления для фиксации жгута. Под ребрами в стержне выполнены продольные пазы для пористого охлаждения волокнистого керамического покрытия и защиты металла лопатки от коррозии воздухом, вытесняющим из покрытия продукты сгорания.The invention relates to gas turbine power plants. The turbine blade with thermal protection includes a base and a feather, on the metal core of which a ceramic coating is applied. New is the fact that the surface of the rod is partitioned by transverse metal ribs, in the gaps between which are attached fibers of ceramic fibers oriented along the ribs. Transverse metal ribs form a locking connection with the harnesses. Along with the harnesses, porcelain concrete with a fibrous filler is introduced into the gaps between the ribs with the formation of a partitioned cermet surface on which a layer of oriented ceramic fibers is applied. The ribs are wavy with concavities and protuberances oriented along the stem of the feather. On the feather rod, the ribs are arranged in the form of a spiral and are formed by a continuous wire, the profile of which has a bow for mounting on the feather rod and recesses for fixing the tow. Under the ribs in the rod, longitudinal grooves are made for porous cooling of a fibrous ceramic coating and for protecting the metal of the blade from corrosion by air, which displaces the products of combustion from the coating.
