Abstract

Лопатка турбины турбомашины содержит по меньшей мере одну нижнюю полку (24), соединенную с основой (16) лопатки нижней соединительной зоной (26), и контур охлаждения, который состоит из по меньшей мере одной полости и нескольких окон (30, 30а) выпуска воздуха, расположенных вдоль задней кромки (22) лопатки. Нижнее из этих окон, окно (30а) выпуска воздуха, расположено вблизи основы (16) лопатки. Это окно имеет боковую стенку (36), оборудованную отверстием (38), которое соединяется с полостью, углубленную стенку (32), нижнюю стенку (34), расположенную со стороны основы лопатки, нижний стык (40), образованный между углубленной стенкой (32) и нижней стенкой (34), и нижнее ребро (42), образованное между нижней стойкой и нижней соединительной зоной (26). Нижний стык (40) и нижнее ребро (42) нижнего окна (30а) выпуска воздуха имеют поперечные сечения, в сущности, закругленной формы, что исключает наличие между отверстием (38) окна и нижней соединительной зоной (26) каких-нибудь выступающих углов.
